text: Consecutive winners

text: Seven franchises have won consecutive Super Bowls, one of which (Pittsburgh) has accomplished it twice:

text:
Green Bay Packers (Super Bowls I and II)
Miami Dolphins (VII and VIII)
Pittsburgh Steelers (twice: IX and X as well as XIII and XIV)
San Francisco 49ers (XXIII and XXIV)
Dallas Cowboys (XXVII and XXVIII)
Denver Broncos (XXXII and XXXIII)
New England Patriots (XXXVIII and XXXIX)

text: No franchise has yet won three Super Bowls in a row, although several have come close:

text:
The Green Bay Packers won the first two Super Bowls, and also won the NFL championship the preceding year.
The Miami Dolphins appeared in three consecutive Super Bowls (VI, VII, and VIII), winning the last two.
The Pittsburgh Steelers won two consecutive Super Bowls (IX and X); the following season they were eliminated in the AFC championship game by the eventual Super Bowl champion Oakland Raiders. They also won two more consecutive Super Bowls (XIII and XIV) for four wins in six seasons.
The San Francisco 49ers won two consecutive Super Bowls (XXIII and XXIV); the following season they were eliminated in the NFC championship by the eventual Super Bowl champion New York Giants.
The Dallas Cowboys won two consecutive Super Bowls (XXVII and XXVIII); the following season they were eliminated in the NFC championship game by the eventual champion San Francisco 49ers. The Cowboys won Super Bowl XXX the following year for three wins in four seasons.
The New England Patriots won Super Bowl XXXVI, which was two years before their consecutive wins in XXXVIII and XXXIX, for three wins in four seasons. They did not make the playoffs in the intervening season (XXXVII). The Patriots also won Super Bowls XLIX and LI and in the intervening season (50) were eliminated in the AFC championship game by the eventual champion Denver Broncos.

text: Consecutive losers

text: Three franchises have lost consecutive Super Bowls:

text:
Buffalo Bills (4) (Super Bowls XXV, XXVI, XXVII, and XXVIII) – The only team to appear in four straight Super Bowls, let alone lose in all four appearances.
Minnesota Vikings (2) (Super Bowls VIII and IX) – They also lost Super Bowl XI, and were knocked out of the playoffs for Super Bowl X by the eventual losers the Dallas Cowboys for three losses in four seasons.
Denver Broncos (2) (Super Bowls XXI and XXII) – They also lost Super Bowl XXIV, but did not even make the playoffs for Super Bowl XXIII for three losses in four seasons.

text: Teams with no Super Bowl appearances

text: Four current teams have never reached the Super Bowl. Two of them held NFL league championships prior to Super Bowl I in the 1966 NFL season:

text:
Cleveland Browns, NFL champions four times in 1950, 1954, 1955, and 1964; appeared in seven other NFL championship games in 1951, 1952, 1953, 1957, 1965, 1968, and 1969; and appeared in three AFC Championship Games in 1986, 1987, and 1989.[68] The Browns are officially viewed as one continuous franchise that began in 1946 as a member of the All-America Football Conference, joined the NFL in 1950, suspended operations from 1996 to 1998, and resumed play in 1999.[69] The Baltimore Ravens were created as an expansion team with former Browns players in 1996, and have since won two Super Bowls.[70]
Detroit Lions, NFL champions four times in 1935, 1952, 1953, and 1957; appeared in one other NFL Championship Game in 1954; and appeared in one NFC Championship Game in 1991[71]
Jacksonville Jaguars, 1995 expansion team; appeared in three AFC Championship Games in 1996, 1999, and 2017.[72]
Houston Texans, 2002 expansion team; Divisional Round appearances in 2011, 2012, and 2016 seasons.

text: In addition, Detroit, Houston, and Jacksonville have hosted Super Bowls, making Cleveland the only current NFL city that has neither hosted nor had its team play in a Super Bowl.

text: Teams with long Super Bowl droughts

text: Although Jacksonville and Houston have never appeared in a Super Bowl, there are teams whose most recent Super Bowl appearance is older than when Jacksonville and Houston joined the NFL (1995 and 2002, respectively), resulting in longer Super Bowl droughts than these teams for the following eight teams.

text: Two of these teams have not appeared in the Super Bowl since before the AFL–NFL merger in 1970:[73]

text:
New York Jets (most recently appeared in Super Bowl III, 1968 season)
Kansas City Chiefs (Super Bowl IV in 1969 season)

text: However, the Jets and the Chiefs are the only non-NFL teams to win the Super Bowl, both being members of the now-defunct AFL at the time.

text: The most recent Super Bowl appearance for the following teams was after the AFL–NFL merger, but prior to the 1995 regular season:

text:
Minnesota Vikings (Super Bowl XI, 1976 season)
Miami Dolphins (Super Bowl XIX, 1984 season)
Cincinnati Bengals (Super Bowl XXIII, 1988 season)
Washington Redskins (Super Bowl XXVI, 1991 season)
Buffalo Bills (Super Bowl XXVIII, 1993 season)
Los Angeles Chargers (played as San Diego Chargers in Super Bowl XXIX, 1994 season)

text: Teams with Super Bowl appearances but no victories

text: Eight teams have appeared in the Super Bowl without ever winning. In descending order of number of appearances, they are:

text:
Minnesota Vikings (4), appeared in Super Bowls IV, VIII, IX, and XI. They won the NFL Championship Game in 1969, the last year before the AFL–NFL merger, but failed to win the subsequent Super Bowl. An NFL expansion team in 1961, they have no pre-Super Bowl league championships.
Buffalo Bills (4), appeared in Super Bowls XXV, XXVI, XXVII, and XXVIII. Their second and last AFL championship was in 1965, the season before the first Super Bowl.
Cincinnati Bengals (2), appeared in Super Bowls XVI and XXIII. An AFL expansion team in 1968, they have no pre-Super Bowl league championships.
Atlanta Falcons (2), appeared in Super Bowls XXXIII and LI. An expansion team in 1966, they have no pre-Super Bowl league championships.
Carolina Panthers (2), appeared in Super Bowls XXXVIII and 50. A post-merger expansion team, their first season was in 1995.
Arizona Cardinals (1), appeared in Super Bowl XLIII. Their last championship was in 1947 as the Chicago Cardinals.
Los Angeles Chargers (1), appeared in Super Bowl XXIX as the San Diego Chargers. Their only AFL championship was in 1963.
Tennessee Titans (1), appeared in Super Bowl XXXIV. They won the first two AFL Championships in 1960 and 1961 as the Houston Oilers.

text: Super Bowl rematches

text: The following teams have faced each other more than once in the Super Bowl:

text:
Dallas Cowboys and Pittsburgh Steelers (3) – Super Bowls X and XIII were won by Pittsburgh, and Super Bowl XXX was won by Dallas. See also Cowboys–Steelers rivalry.
Miami Dolphins and Washington Redskins (2) – Super Bowl VII was won by Miami, and Super Bowl XVII was won by Washington.
Cincinnati Bengals and San Francisco 49ers (2) – Super Bowls XVI and XXIII were both won by San Francisco.
Buffalo Bills and Dallas Cowboys (2) – Super Bowls XXVII and XXVIII, the only rematch in consecutive seasons, were both won by Dallas.
New England Patriots and New York Giants (2) – Super Bowls XLII and XLVI were both won by New York.
New England Patriots and Philadelphia Eagles (2) – Super Bowl XXXIX was won by New England, Super Bowl LII was won by Philadelphia.

question_text: what percentage of the yankees do the steinbrenners own

root

text: Principal owners[edit]

text: During the 1901 and 1902 seasons, the franchise played in Baltimore as the "Baltimore Orioles". They became defunct, but were purchased by William Stephen Devery and Frank J. Farrell for $18,000 and moved to New York in 1903.[3] Jacob Ruppert and Tillinghast L'Hommedieu Huston purchased the Yankees in 1915,[4] and Ruppert bought out Huston in 1922.[5]

tag: p

text: Dan Topping, Larry MacPhail, and Del Webb purchased the Yankees from Ruppert's estate in 1945.[6] Topping and Webb forced MacPhail out of the Yankees ownership group due to his confrontational behavior after the 1947 World Series.[7] In 1964, Topping and Webb sold the team to CBS,[8] during which time the franchise struggled. Selling the team at a loss,[9] CBS sold the team to a group headed by George Steinbrenner in 1973.[10] While Steinbrenner initially owned less than half of the team, he bought out many of his partners, eventually owning 70% of the team.[11][12] John McMullen, one of Steinbrenner's limited partners, said, "There is nothing in life quite so limited as being a limited partner of George Steinbrenner."[13]

text: Under Steinbrenner's ownership, YankeeNets was formed after a merger of the business operations of the Yankees and New Jersey Nets.[14] After the Nets were sold to Bruce Ratner, YankeeNets became a limited liability company (LLC) known as Yankee Global Enterprises.[15] The LLC owns the Yankees and the YES Network. Hal Steinbrenner succeeded his father as control person of the Yankees in 2008.[16]

document_title: Cerebral cortex

question_text: where are the association areas of the brain located

text: Cerebral cortex

text: Structure[edit]

text: Layers[edit]

text: The different cortical layers each contain a characteristic distribution of neuronal cell types and connections with other cortical and subcortical regions. There are direct connections between different cortical areas and indirect connections via the thalamus, for example. One of the clearest examples of cortical layering is the stria of Gennari in the primary visual cortex. This is a band of whiter tissue that can be observed with the naked eye in the fundus of the calcarine sulcus of the occipital lobe. The Stria of Gennari is composed of axons bringing visual information from the thalamus into layer four of the visual cortex.

text: Staining cross-sections of the cortex to reveal the position of neuronal cell bodies and the intracortical axon tracts allowed neuroanatomists in the early 20th century to produce a detailed description of the laminar structure of the cortex in different species. After the work of Korbinian Brodmann (1909) the neurons of the cerebral cortex are grouped into six main layers, from outside (pial surface) to inside (white matter):

text:
Layer I, the molecular layer, contains few scattered neurons and consists mainly of extensions of apical dendritic tufts of pyramidal neurons and horizontally oriented axons, as well as glial cells.[3] During development Cajal-Retzius[4] and subpial granular layer cells[5] are present in this layer. Also, some spiny stellate cells can be found here. Inputs to the apical tufts are thought to be crucial for the ‘‘feedback interactions in the cerebral cortex involved in associative learning and attention.[6] While it was once thought that the input to layer I came from the cortex itself,[7] it is now realized that layer I across the cerebral cortex mantle receives substantial input from ‘‘matrix or M-type thalamus cells[8] (in contrast to ‘‘core or C-type that go to layer IV).[9]
Layer II, the external granular layer, contains small pyramidal neurons and numerous stellate neurons.
Layer III, the external pyramidal layer, contains predominantly small and medium-size pyramidal neurons, as well as non-pyramidal neurons with vertically oriented intracortical axons; layers I through III are the main target of interhemispheric corticocortical afferents, and layer III is the principal source of corticocortical efferents.
Layer IV, the internal granular layer, contains different types of stellate and pyramidal neurons, and is the main target of thalamocortical afferents from thalamus type C neurons[9] as well as intra-hemispheric corticocortical afferents.
Layer V, the internal pyramidal layer, contains large pyramidal neurons which give rise to axons leaving the cortex and running down to subcortical structures (such as the basal ganglia). In the primary motor cortex of the frontal lobe, layer V contains Betz cells, whose axons travel through the internal capsule, the brain stem and the spinal cord forming the corticospinal tract, which is the main pathway for voluntary motor control.
Layer VI, the polymorphic or multiform layer, contains few large pyramidal neurons and many small spindle-like pyramidal and multiform neurons; layer VI sends efferent fibers to the thalamus, establishing a very precise reciprocal interconnection between the cortex and the thalamus.[10] That is, layer VI neurons from one cortical column connect with thalamus neurons that provide input to the same cortical column. These connections are both excitatory and inhibitory. Neurons send excitatory fibers to neurons in the thalamus and also send collaterals to the thalamic reticular nucleus that inhibit these same thalamus neurons or ones adjacent to them.[11] One theory is that because the inhibitory output is reduced by cholinergic input to the cerebral cortex, this provides the brainstem with adjustable "gain control for the relay of lemniscal inputs".[11]

text: The cortical layers are not simply stacked one over the other; there exist characteristic connections between different layers and neuronal types, which span all the thickness of the cortex. These cortical microcircuits are grouped into cortical columns and minicolumns. It has been proposed that the minicolumns are the basic functional units of the cortex.[12] In 1957, Vernon Mountcastle showed that the functional properties of the cortex change abruptly between laterally adjacent points; however, they are continuous in the direction perpendicular to the surface. Later works have provided evidence of the presence of functionally distinct cortical columns in the visual cortex (Hubel and Wiesel, 1959),[13] auditory cortex, and associative cortex.

text: Cortical areas that lack a layer IV are called agranular. Cortical areas that have only a rudimentary layer IV are called dysgranular.[14] Information processing within each layer is determined by different temporal dynamics with that in the layers II/III having a slow 2 Hz oscillation while that in layer V having a fast 10–15 Hz one.[15]

text: Areas[edit]

text: Based on the differences in lamination the cerebral cortex can be classified into two parts, the large area of neocortex and the much smaller area of allocortex:

text:
The neocortex (also known as the isocortex or neopallium) is the part of the mature cerebral cortex with six distinct layers. Examples of neocortical areas include the granular primary motor cortex, also known as Brodmann area 4, and the striate primary visual cortex, or Brodmann area 17. The neocortex has two types of cortices, the true isocortex and the proisocortex. The proisocortex contains Brodmann areas 24, 25, and 32
The allocortex is the part of the cerebral cortex with less than six layers and has three regions, the paleocortex with three cortical laminae and the archicortex which has four or five, and a transitional area adjacent to the allocortex, the periallocortex. Examples of allocortex are the olfactory cortex and the hippocampus.

text: There is a transitional area between the neocortex and the allocortex called the paralimbic cortex, where layers 2, 3 and 4 are merged. This area incorporates the proisocortex of the neocortex and the periallocortex of the allocortex. In addition, the cerebral cortex may be classified on the basis of gross topographical conventions into four lobes (named after the four skull bones protecting them): the temporal lobe, the occipital lobe, the parietal lobe, and the frontal lobe.

text: Brodmann areas[edit]

text: Different parts of the cerebral cortex are involved in different cognitive and behavioral functions. The differences show up in a number of ways: the effects of localized brain damage, regional activity patterns exposed when the brain is examined using functional imaging techniques, connectivity with subcortical areas, and regional differences in the cellular architecture of the cortex. Neuroscientists describe most of the cortex—the part they call the neocortex—as having six layers, but not all layers are apparent in all areas, and even when a layer is present, its thickness and cellular organization may vary. Scientists have constructed maps of cortical areas on the basis of variations in the appearance of the layers as seen with a microscope. One of the most widely used schemes came from Korbinian Brodmann, who split the cortex into 51 different areas and assigned each a number (many of these Brodmann areas have since been subdivided). For example, Brodmann area 1 is the primary somatosensory cortex, Brodmann area 17 is the primary visual cortex, and Brodmann area 25 is the anterior cingulate cortex.[16]

text: Thickness[edit]

text: For mammals, species with larger brains (in absolute terms, not just in relation to body size) tend to have thicker cortices.[17] The range, however, is not very great; only a factor of 7 differentiates between the thickest and thinnest cortices. The smallest mammals, such as shrews, have a neocortical thickness of about 0.5 mm; the ones with the largest brains, such as humans and fin whales, have thicknesses of 2.3–2.8 mm. There is an approximately logarithmic relationship between brain weight and cortical thickness.[17]

text: Magnetic resonance imaging (MRI) of the brain makes it possible to get a measure for the thickness of the human cerebral cortex and relate it to other measures. The thickness of different cortical areas varies but in general, sensory cortex is thinner than motor cortex.[18] One study has found some positive association between the cortical thickness and intelligence.[19] Another study has found that the somatosensory cortex is thicker in migraine sufferers, though it is not known if this is the result of migraine attacks or the cause of them.[20][21] A later study using a larger patient population reports no change in the cortical thickness in migraine sufferers.[22] A genetic disorder of the cerebral cortex, whereby decreased folding in certain areas results in a microgyrus, where there are four layers instead of six, is in some instances seen to be related to dyslexia.[23]

text: Folds[edit]

text: The cerebral cortex is folded in a way that allows a large surface area to fit within the confines of the skull. When unfolded, each cerebral hemisphere cortex has a total surface area of about 1.3 square feet (0.12 m2).[24] The folding is inward away from the surface of the brain, and is also present on the medial surface of the brain within the longitudinal fissure. The folding creates a looping, meandering, 'worm-pile' appearance of the surface of the brain. The peaks of folds are called gyri (singular gyrus), and the valleys are called sulci (singular sulcus).

text: Blood supply and drainage[edit]

text: This section needs expansion. You can help by adding to it. (February 2017)

text: Blood is supplied to the cerebral cortex via the cerebral circulation.

text: Development[edit]

text: The ontogenic development of the cerebral cortex is a complex and finely tuned process influenced by the interplay between genes and environment.[25] The cerebral cortex develops from the most anterior part of the neural plate, a specialized part of the embryonic ectoderm.[26] The neural plate folds and closes to form the neural tube. From the cavity inside the neural tube develops the ventricular system, and, from the epithelial cells of its walls, the neurons and glia of the nervous system. The most anterior (front, or cranial) part of the neural plate, the prosencephalon, which is evident before neurulation begins, gives rise to the cerebral hemispheres and its later cortex.[27]

text: Cortical neurons are generated within the ventricular zone, next to the ventricles. At first, this zone contains progenitor cells, which divide to produce glial cells and neurons.[28] The glial fibers produced in the first divisions of the progenitor cells are radially oriented, spanning the thickness of the cortex from the ventricular zone to the outer, pial surface, and provide scaffolding for the migration of neurons outwards from the ventricular zone.[29][30] The first divisions of the progenitor cells are symmetric, which duplicates the total number of progenitor cells at each mitotic cycle. Then, some progenitor cells begin to divide asymmetrically, producing one postmitotic cell that migrates along the radial glial fibers, leaving the ventricular zone, and one progenitor cell, which continues to divide until the end of development, when it differentiates into a glial cell or an ependymal cell. As the G1 phase of mitosis is elongated, in what is seen as selective cell-cycle lengthening, the newly-born neurons migrate to more superficial layers of the cortex.[31] The migrating daughter cells become the pyramidal cells of the cerebral cortex.[32] The development process is time ordered and regulated by hundreds of genes and epigenetic regulatory mechanisms.[33]

text: The layered structure of the mature cerebral cortex is formed during development. The first pyramidal neurons generated migrate out of the ventricular zone and subventricular zone, together with reelin producing Cajal–Retzius neurons, from the preplate. Next, a cohort of neurons migrating into the middle of the preplate divides this transient layer into the superficial marginal zone, which will become layer one of the mature neocortex, and the subplate,[34] forming a middle layer called the cortical plate. These cells will form the deep layers of the mature cortex, layers five and six. Later born neurons migrate radially into the cortical plate past the deep layer neurons, and become the upper layers (two to four). Thus, the layers of the cortex are created in an inside-out order.[35] The only exception to this inside-out sequence of neurogenesis occurs in the layer I of primates, in which, in contrast to rodents, neurogenesis continues throughout the entire period of corticogenesis.[36]

text: The map of functional cortical areas, which include primary motor and visual cortex, originates from a 'protomap',[37] which is regulated by molecular signals such as fibroblast growth factor FGF8 early in embryonic development.[38][39] These signals regulate the size, shape, and position of cortical areas on the surface of the cortical primordium, in part by regulating gradients of transcription factor expression, through a process called cortical patterning. Examples of such transcription factors include the genes EMX2 and PAX6.[40] Together, both transcription factors form an opposing gradient of expression. Pax6 is highly expressed at the rostral lateral pole, while Emx2 is highly expressed in the caudomedial pole. The establishment of this gradient is important for proper development. For example, mutations in Pax6 can cause expression levels of Emx2 to expand out of its normal expression domain, which would ultimately lead to an expansion of the areas normally derived from the caudal medial cortex, such as the visual cortex. On the contrary, if mutations in Emx2 occur, it can cause the Pax6-expressing domain to expand and result in the frontal and motor cortical regions enlarging. Therefore, researchers believe that similar gradients and signaling centers next to the cortex could contribute to the regional expression of these transcription factors.[41]

text: Two very well studied patterning signals for the cortex include FGF and retinoic acid. Interestingly, if FGFs are misexpressed in different areas of the developing cortex, cortical patterning is disrupted. Specifically, when Fgf8 is increased in the anterior pole, Emx2 is downregulated and a caudal shift in the cortical region occurs. This ultimately causes an expansion of the rostral regions. Therefore, Fgf8 and other FGFs play a role in the regulation of expression of Emx2 and Pax6 and represent how the cerebral cortex can become specialized for different functions.[41]

text: Rapid expansion of the cortical surface area is regulated by the amount of self-renewal of radial glial cells and is partly regulated by FGF and Notch genes.[42] During the period of cortical neurogenesis and layer formation, many higher mammals begin the process of gyrification, which generates the characteristic folds of the cerebral cortex.[43][44] Gyrification is regulated by a DNA-associated protein Trnp1[45] and by FGF and SHH signaling[46][47]

text: The cerebral cortex is composed of a heterogenous population of cells that give rise to different cell types. The majority of these cells are derived from radial glia migration that form the different cell types of the neocortex and it is a period associated with an increase in neurogenesis. Similarly, the process of neurogenesis regulates lamination to form the different layers of the cortex. During this process there is an increase in the restriction of cell fate that begins with earlier progenitors giving rise to any cell type in the cortex and later progenitors giving rise only to neurons of superficial layers. This differential cell fate creates an inside-out topography in the cortex with younger neurons in superficial layers and older neurons in deeper layers. In addition, laminar neurons are stopped in S or G2 phase in order to give a fine distinction between the different cortical layers. Laminar differentiation is not fully complete until after birth since during development laminar neurons are still sensitive to extrinsic signals and environmental cues.[48]

text: Although the majority of the cells that compose the cortex are derived locally from radial glia there is a subset population of neurons that migrate from other regions. Radial glia give rise to neurons that are pyramidal in shape and use glutamate as a neurotransmitter, however these migrating cells contribute neurons that are stellate-shaped and use GABA as their main neurotransmitter. These GABAergic neurons are generated by progenitor cells in the medial ganglionic eminence (MGE) that migrate tangentially to the cortex via the subventricular zone. This migration of GABAergic neurons is particularly important since GABA receptors are excitatory during development. This excitation is primarily driven by the flux of chloride ions through the GABA receptor, however in adults chloride concentrations shift causing an inward flux of chloride that hyperpolarizes postsynaptic neurons.[41]

text: Evolution[edit]

text: Of all the different brain regions, the cerebral cortex shows the largest evolutionary variation and has evolved most recently.[2] In contrast to the highly conserved circuitry of the medulla oblongata, for example, which serves critical functions such as regulation of heart and respiration rates, many areas of the cerebral cortex are not strictly necessary for survival. Thus, the evolution of the cerebral cortex has seen the advent and modification of new functional areas—particularly association areas that do not directly receive input from outside the cortex.[2]

text: A key theory of cortical evolution is embodied in the radial unit hypothesis and related protomap hypothesis, first proposed by Rakic.[49] This theory states that new cortical areas are formed by the addition of new radial units, which is accomplished at the stem cell level. The protomap hypothesis states that the cellular and molecular identity and characteristics of neurons in each cortical area are specified by cortical stem cells, known as radial glial cells, in a primordial map. This map is controlled by secreted signaling proteins and downstream transcription factors.[50][51][52]

text: Function[edit]

text: Connections[edit]

text: The cerebral cortex is connected to various subcortical structures such as the thalamus and the basal ganglia, sending information to them along efferent connections and receiving information from them via afferent connections. Most sensory information is routed to the cerebral cortex via the thalamus. Olfactory information, however, passes through the olfactory bulb to the olfactory cortex (piriform cortex). The majority of connections are from one area of the cortex to another, rather than from subcortical areas; Braitenberg and Schüz (1998) claim that in primary sensory areas, at the cortical level where the input fibres terminate, up to 20% of the synapses are supplied by extracortical afferents but that in other areas and other layers the percentage is likely to be much lower.[53]

text: Cortical areas[edit]

text: The cortex is commonly described as comprising three parts: sensory, motor, and association areas.

text: Sensory areas[edit]

text: The sensory areas are the cortical areas that receive and process information from the senses. Parts of the cortex that receive sensory inputs from the thalamus are called primary sensory areas. The senses of vision, audition, and touch are served by the primary visual cortex, primary auditory cortex and primary somatosensory cortex respectively. In general, the two hemispheres receive information from the opposite (contralateral) side of the body. For example, the right primary somatosensory cortex receives information from the left limbs, and the right visual cortex receives information from the left visual field. The organization of sensory maps in the cortex reflects that of the corresponding sensing organ, in what is known as a topographic map. Neighboring points in the primary visual cortex, for example, correspond to neighboring points in the retina. This topographic map is called a retinotopic map. In the same way, there exists a tonotopic map in the primary auditory cortex and a somatotopic map in the primary sensory cortex. This last topographic map of the body onto the posterior central gyrus has been illustrated as a deformed human representation, the somatosensory homunculus, where the size of different body parts reflects the relative density of their innervation. Areas with lots of sensory innervation, such as the fingertips and the lips, require more cortical area to process finer sensation.

text: Motor areas[edit]

text: The motor areas are located in both hemispheres of the cortex. They are shaped like a pair of headphones stretching from ear to ear. The motor areas are very closely related to the control of voluntary movements, especially fine fragmented movements performed by the hand. The right half of the motor area controls the left side of the body, and vice versa.

text: Two areas of the cortex are commonly referred to as motor:

text:
Primary motor cortex, which executes voluntary movements[citation needed]
Supplementary motor areas and premotor cortex, which select voluntary movements.[citation needed]

text: In addition, motor functions have been described for:

text:
Posterior parietal cortex, which guides voluntary movements in space
Dorsolateral prefrontal cortex, which decides which voluntary movements to make according to higher-order instructions, rules, and self-generated thoughts.

text: Just underneath the cerebral cortex are interconnected subcortical masses of grey matter called basal ganglia (or nuclei). The basal ganglia receive input from the substantia nigra of the midbrain and motor areas of the cerebral cortex, and send signals back to both of these locations. They are involved in motor control. They are found lateral to the thalamus. The main components of the basal ganglia are the caudate nucleus, the putamen, the globus pallidus, the substantia nigra, the nucleus accumbens, and the subthalamic nucleus. The putamen and globus pallidus are also collectively known as the lentiform nucleus, because together they form a lens-shaped body. The putamen and caudate nucleus are also collectively called the corpus striatum after their striped appearance.[54][55]

text: Association areas[edit]

text: The association areas are the parts of the cerebral cortex that do not belong to the primary regions. They function to produce a meaningful perceptual experience of the world, enable us to interact effectively, and support abstract thinking and language. The parietal, temporal, and occipital lobes - all located in the posterior part of the cortex - integrate sensory information and information stored in memory. The frontal lobe or prefrontal association complex is involved in planning actions and movement, as well as abstract thought. Globally, the association areas are organized as distributed networks.[56] Each network connects areas distributed across widely spaced regions of the cortex. Distinct networks are positioned adjacent to one another yielding a complex series of interwoven networks. The specific organization of the association networks is debated with evidence for interactions, hierarchical relationships, and competition between networks.[57] In humans, association networks are particularly important to language function. In the past it was theorized that language abilities are localized in the left hemisphere in areas 44/45, the Broca's area, for language expression and area 22, the Wernicke's area, for language reception. However, language is no longer limited to easily identifiable areas. More recent research suggests that the processes of language expression and reception occur in areas other than just those structures around the lateral sulcus, including the frontal lobe, basal ganglia, cerebellum, and pons.[58]

text: Neurodegenerative diseases such as Alzheimer's disease and Lafora disease, show as a marker, an atrophy of the grey matter of the cerebral cortex.[59]

text: There are many neurodevelopmental abnormalities that can lead to a wide variety of behavioral and cognitive deficits. There are several situations in development in which both intrinsic and extrinsic factors can highly influence the course of nervous system formation. One very prominent intrinsic factor (random gene mutation) has given rise to many different classes of neurodevelopmental disorders. For example, Fragile X-Syndrome is a neurodevelopmental disease characterized by poor eye contact with others, an extreme aversion to physical/social contact, and obsessive repetition in behavioral patterns.[60] This is an X-linked chromosomal disorder in which the FMR1 gene is found to have nearly 200 copies, instead of its intended 30. This causes the gene to become heavily methylated, which subsequently turns off expression of FMR1. Efficient functioning of this gene is known to play a role in localized protein synthesis at dendritic spines, which is essential for proper synaptogenesis and learning and memory function.[60]

text: Another primary example of intrinsic neurodevelopmental deficits is Rett Syndrome, which is an X-linked single gene mutation characterized by a loss of speech and hand coordination, intellectual regression and progressive loss of motor control.[60] This disorder is thought to arise from a mutation in the MeCP2 gene, which encodes for a transcription factor associated with chromatin remodeling. Mutations in this gene have been linked to a decreased expression of the gene that codes for BDNF (brain-derived neurotrophic factor), which is a common gene used in neurodevelopment.[60]

text: Apart from intrinsic gene mutation, there are many extrinsic (environmental) factors that can greatly influence the neurodevelopmental process. One of the most commonly studied factors is the effect of maternal alcohol consumption during gestation. Infants born with defects from this factor are said to have Fetal Alcohol Spectrum Disorder (FASD). FASD is used to describe a collection of developmental disorders associated with the consumption of alcohol whilst pregnant.[61] The spectrum includes individuals with both extreme and mild FASD which present with a variety of neurocognitive and neurobehavioral deficits. This includes deficits is sustained and focused attention, learning and memory problems, verbal processing problems, receptive language difficulties, hyperactivity, as well as a slew of psychiatric impairments.[61] Apoptotic cell death caused by an excess of glutamate activity and GABA withdrawal is thought to play a role in the loss of neuronal fibers critical for normal brain development. In addition to neuronal death, there is evidence suggesting that an improper formation of interneuronal connections and cell adhesion molecule malformation are also associated with FASD. Improper neuronal migration and synaptogenesis have been shown to occur is several cases of FASD, which could explain the extreme deficits in learning and memory.[61]

text: Other animals[edit]

text: The cerebral cortex is derived from the pallium, a layered structure found in the forebrain of all vertebrates. The basic form of the pallium is a cylindrical layer enclosing fluid-filled ventricles. Around the circumference of the cylinder are four zones, the dorsal pallium, medial pallium, ventral pallium, and lateral pallium, which are thought respectively to give rise to the neocortex, hippocampus, amygdala, and olfactory cortex.

text: Until recently no counterpart to the cerebral cortex had been recognized in invertebrates. However, a study published in the journal Cell in 2010, based on gene expression profiles, reported strong affinities between the cerebral cortex and the mushroom bodies of ragworms.[62] Mushroom bodies are structures in the brains of many types of worms and arthropods that are known to play important roles in learning and memory; the genetic evidence indicates a common evolutionary origin, and therefore indicates that the origins of the earliest precursors of the cerebral cortex date back to the early Precambrian era.

document_title: History of the United States public debt

question_text: when was the last time the us had no deficit

text: Early history[edit]

text: Except for about a year during 1835–1836, the United States has continuously had a fluctuating public debt since its Constitution went into effect on March 4, 1789. During the American Revolution, the Continental Congress, under the Articles of Confederation, amassed huge war debts, but lacked the power to repay these obligations through taxation or duties on imports.[1][2]

text: On the founding of the United States, the financial affairs of the new federation were in disarray, exacerbated by an economic crisis in urban commercial centers.[3] In 1790, Secretary of the Treasury Alexander Hamilton pushed for Congress to pass a financial plan, called the First Report on the Public Credit,[4] a controversial part of which involved the federal government assuming state debts incurred during the Revolutionary War.[5] Northern states had accumulated a huge amount of debt during the war, amounting to $21.5 million, and wanted the federal government to assume their burden. The Southern states, which had lower or no debts, whose citizens would effectively pay a portion of this debt if the federal government assumed it, were disinclined to accept the proposal. Some states, including Virginia, had already paid off almost half of their debts, and felt that their taxpayers should not be assessed again to bail out the less provident, and further argued that the plan was beyond the constitutional power of the new government. James Madison, then a representative from Virginia, led a group of legislators from the South in blocking the provision and prevent the plan from gaining approval. Jefferson supported Madison[6] The plan was finally adopted as part of the Compromise of 1790, as the Funding Act of 1790. The compromise meant that the state debts were all picked up by the federal Treasury, and the permanent national capital would be located in the South, along the Virginia-Maryland border in what became the District of Colombia.

text: The assumption issue[edit]

text: Historian Max M. Edling has explained how assumption worked. It was the critical issue; the location of the capital was a bargaining ploy. Hamilton proposed that the federal Treasury take over and pay off all the debt that states had incurred to pay for the American Revolution. The Treasury would issue bonds that rich people would buy, thereby giving the rich a tangible stake in the success of the national government. Hamilton proposed to pay off the new bonds with revenue from a new tariff on imports. Jefferson originally approved the scheme, but Madison had turned him around by arguing that federal control of debt would consolidate too much power in the national government. Edling points out that after its passage in 1790, the assumption was accepted. Madison did try to pay speculators below 100%, but they were paid the face value of the state debts they held regardless of how little they paid for them. When Jefferson became president he continued the system. The credit of the U.S. was solidly established at home and abroad, and Hamilton was successful in signing up many of the bondholders in his new Federalist Party. Good credit allowed Jefferson's Treasury Secretary Albert Gallatin to borrow in Europe to finance the Louisiana Purchase in 1803, as well as to borrow to finance the War of 1812.[7]

text: The Southern states extracted a major concession from Hamilton in the recalculation of their debt under the fiscal plan.[8] For example, in the case of Virginia, a zero-sum arrangement was contrived, in which Virginia paid $3.4 million to the federal government, and received exactly that amount in federal compensation.[9] The revision of Virginia’s debt, coupled with Potomac residence issue, ultimately netted it over $13 million.[10] Another result of federal assumption of state debts was to give the federal government much more power by placing the country's most serious financial obligation in the hands of the federal government rather than the state governments. The federal government was able to avoid competing in interest with the States.

text: The debts of the federal government on January 1, 1791 amounted to $75,463,476.52, of which about $40 million was domestic debt, $12 million was foreign debt, and $18.3 million were state debts assumed by the federal government, of the $21.5 million that had been authorized.[11]

text: 1790s to 1910[edit]

text: To reduce the debt, from 1796 to 1811 there were 14 budget surpluses and 2 deficits. There was a sharp increase in the debt as a result of the War of 1812. In the 20 years following that war, there were 18 surpluses. The United States actually paid off its debt entirely in January 1835, only to begin accruing debt anew by 1836 (the debt on January 1, 1836 was $37,000).[12][13]

text: Another sharp increase in the debt occurred as a result of the Civil War. The debt was just $65 million in 1860, but passed $1 billion in 1863 and reached $2.7 billion by the end of the war. During the following 47 years, there were 36 surpluses and 11 deficits. During this period 55% of the national debt was paid off.

text: World War I and Great Depression[edit]

text: Debt increased again during World War I (1914–1918), reaching $25.5 billion at its conclusion. Approximately $17 billion in debt was raised through the selling of Liberty Bonds to the general public to finance the U.S.'s military effort. The war was followed by 11 consecutive surpluses that saw the debt reduced by 36% by the end of the 1920s.[14]

text: Warren G. Harding was elected president in 1920 and believed the federal government should be fiscally managed in a way similar to private sector businesses. He had campaigned in 1920 on the slogan, "Less government in business and more business in government."[15] Under Harding, federal spending declined from $6.3 billion in 1920 to $5 billion in 1921 and $3.3 billion in 1922. Over the course of the 1920s, under the leadership of Calvin Coolidge, the national debt was reduced by one third.[16] The decrease was even greater when the growth in GDP and inflation is taken into account.

text: Debt held by the public was $15.05 billion or 16.5% of GDP in 1930. When Franklin D. Roosevelt took office in 1933, the public debt was almost $20 billion, 20% of GDP. Decreased tax revenues and spending on social programs during the Great Depression increased the debt and by 1936, the public debt had increased to $33.7 billion, approximately 40% of GDP.[17] During its first term, the Roosevelt administration ran large annual deficits of between 2 and 5% of GDP. By 1939, the debt held by the public had increased to $39.65 billion or 43% of GDP. The buildup and involvement in World War II during the presidencies of F.D. Roosevelt and Harry S. Truman led to the largest increase in public debt. Public debt rose over 100% of GDP to pay for the mobilization before and during the war. Public debt was $251.43 billion or 112% of GDP at the conclusion of the war in 1945 and was $260 billion in 1950.

text: After World War II[edit]

text: The public debt fell rapidly after the end of World War II under the presidency of Harry S. Truman, as the U.S. and the rest of the world experienced a post-war economic expansion. Unlike previous wars, the Korean War (1950–53) was largely financed by taxation and did not lead to an increase in the public debt.[18]

text: Growth rates in Western countries began to slow in the mid-1960s. Beginning in the mid-1970s and afterwards, U.S. national debt began to increase faster than GDP.[19][20]

text: The public debt reached a post-World War II low of 24.6% in 1974.[14][21] In that year, the Congressional Budget and Impoundment Control Act of 1974 reformed the budget process to allow Congress to challenge the president's budget more easily, and, as a consequence, deficits became increasingly difficult to control.[22] National debt held by the public increased from its postwar low of 24.6% of GDP in 1974 to 26.2% in 1980.[23]

text: Debt held by the public relative to GDP rose rapidly again in the 1980s. President Ronald Reagan's economic policies lowered tax rates (Reagan slashed the top income tax rate from 70% to 28%, although bills passed in 1982 and 1984 later partially reversed those tax cuts.)[22][24] and increased military spending, while congressional Democrats blocked cuts to social programs.[20][22][24][25] As a result, debt as a share of GDP increased from 26.2% in 1980 to 40.9% in 1988,[23] and it continued to rise during the presidency of George H. W. Bush, reaching 48.3% of GDP in 1992.[14][26]

text: Debt held by the public reached a high of 49.5% of GDP at the beginning of President Clinton's first term. However, it fell to 34.5% of GDP by the end of Clinton's presidency due in part to decreased military spending, increased taxes (in 1990, 1993 and 1997), and increased tax revenue resulting from the 1990s boom.[14][21][27][28][29] The budget controls instituted in the 1990s successfully restrained fiscal action by the Congress and the President and together with economic growth contributed to the budget surpluses at the end of the decade.[30] The surpluses led to a decline in the public debt from about 43% of GDP in 1998 to about 33% by 2001.[30]

text: In the early 21st century, debt held by the public relative to GDP rose again due in part to the Bush tax cuts and increased military spending caused by the wars in the Middle East and a new entitlement Medicare D program. During the presidency of George W. Bush, debt held by the public increased from $3.339 trillion in September 2001 to $6.369 trillion by the end of 2008.[31][32] In the aftermath of the global financial crisis of 2007–08 and related significant revenue declines and spending increases, debt held by the public increased to $11.917 trillion by the end of July 2013, under the presidency of Barack Obama.[31][33]

text: 2011 credit rating downgrade[edit]

text: On August 5, 2011, the United States debt-ceiling crisis of 2011, the credit rating agency Standard & Poor's downgraded the rating of the federal government from AAA to AA+. It was the first time the U.S. had been downgraded since it was originally given a AAA rating on its debt by Moody's in 1917.[34] BBC News reported that Standard & Poor's had "lost confidence" in the ability of the U.S. government to make decisions.[35]

text: Changes in debt by political affiliation[edit]

text: The President proposes a national budget to Congress, which has final say over the document but rarely appropriates more than what the President requests.[36]

text: Economist Mike Kimel has noted that the former Democratic Presidents (Bill Clinton, Jimmy Carter, Lyndon B. Johnson, John F. Kennedy, and Harry S. Truman) all reduced public debt as a share of GDP, while the last four Republican Presidents (George W. Bush, George H. W. Bush, Ronald Reagan and Gerald Ford) all oversaw an increase in the country's indebtedness.[37] Economic historian J. Bradford DeLong, observed a contrast not so much between Republicans and Democrats but between Democrats and "old-style Republicans (Eisenhower and Nixon)" on one hand (decreasing debt) and "new-style Republicans" on the other (increasing debt).[38][39] David Stockman, former director of the Office of Management and Budget, blamed the "ideological tax-cutters" of the Reagan administration for the increase of national debt during the 1980s.[40] Former Treasury official Bruce Bartlett attributed the increase in the national debt since the 1980s to the policy of "starve the beast".[41][42] While noting that George H.W. Bush's budget deal in 1990 was one of the reasons for improvement of the fiscal situation in 1990s, Bartlett was highly critical of George W. Bush for creating budget deficits by reducing tax rates and increasing spending in the early 2000s.[43][44]

text: Causes of recent changes in debt[edit]

text: Public debt is the cumulative result of budget deficits; that is, government spending exceeding revenues.

text: 2001 vs. 2009[edit]

text: According to the Congressional Budget Office, the United States last had a budget surplus during fiscal year 2001. From fiscal years 2001 to 2009, spending increased by 6.5% of gross domestic product (from 18.2% to 24.7%) while taxes declined by 4.7% of GDP (from 19.5% to 14.8%). Spending increases (expressed as percentage of GDP) were in the following areas: Medicare and Medicaid (1.7%), defense (1.6%), income security such as unemployment benefits and food stamps (1.4%), Social Security (0.6%) and all other categories (1.2%). Revenue reductions were individual income taxes (−3.3%), payroll taxes (−0.5%), corporate income taxes (−0.5%) and other (−0.4%).

text: The 2009 spending level was the highest relative to GDP in 40 years, while the tax receipts were the lowest relative to GDP in 40 years. The next highest spending year was 1985 (22.8%), while the next lowest tax year was 2004 (16.1%).[45]

text: 2001 vs. 2011[edit]

text: In June 2012, the Congressional Budget Office summarized the cause of change between its January 2001 estimate of a $5.6 trillion cumulative surplus between 2002 and 2011 and the actual $6.1 trillion cumulative deficit that occurred, an unfavorable "turnaround" or debt increase of $11.7 trillion. Tax rate cuts and slower-than-expected growth reduced revenues by $6.1 trillion and spending was $5.6 trillion higher. Of this total, the CBO attributes 72% to legislated tax rate cuts and spending increases and 27% to economic and technical factors. Of the latter, 56% occurred from 2009 to 2011.[46][47]

text: The difference between the projected and actual debt in 2011, the budget office said, could be attributed largely to:

text:
$3.5 trillion – Economic changes (including lower than expected tax revenues and higher safety net spending due to recession)
$1.6 trillion – Bush Tax Cuts (EGTRRA and JGTRRA), primarily tax rate cuts but also some smaller spending increases
$1.5 trillion – Increased non-defense discretionary spending
$1.4 trillion – Wars in Afghanistan and Iraq
$1.4 trillion – Incremental interest due to higher debt balances
$0.9 trillion – Obama stimulus and tax cuts (ARRA and Tax Act of 2010)[47]

text: The U.S. budget situation has deteriorated significantly since 2001, when the CBO forecast average annual surpluses of approximately $850 billion from 2009–2012. The average deficit forecast in each of those years as of June 2009 was approximately $1,215 billion. The New York Times analyzed this roughly $2 trillion "swing", separating the causes into four major categories along with their share:

text:
Recessions or the business cycle (37%);
Policies enacted by President Bush (33%);
Policies enacted by President Bush and supported or extended by President Obama (20%); and
New policies from President Obama (10%).

text: Several other articles and experts explained the causes of change in the debt position.[48][49][50]

text: 2008 vs. 2009[edit]

text: In October 2009, the Congressional Budget Office (CBO) gave the reasons for the higher budget deficit in 2009 ($1,410 billion, i.e. $1.41 trillion) over that of 2008 ($460 billion). The major changes included: declines in tax receipt of $320 billion due to the effects of the recession and another $100 billion due to tax rate cuts in the stimulus bill (the American Recovery and Reinvestment Act or ARRA); $245 billion for the Troubled Asset Relief Program (TARP) and other bailout efforts; $100 billion in additional spending for ARRA; and another $185 billion due to increases in primary budget categories such as Medicare, Medicaid, unemployment insurance, Social Security, and Defense – including the war effort in Afghanistan and Iraq. This was the highest budget deficit relative to GDP (9.9%) since 1945.[51] The national debt increased by $1.9 trillion during FY2009, versus the $1.0 trillion increase during 2008.[52]

text: The Obama Administration also made four significant accounting changes to more accurately report total federal government spending. The four changes were:

text:
Account for the wars in Iraq and Afghanistan ("overseas military contingencies") in the budget, rather than through supplemental appropriations
Assume the Alternative Minimum Tax is indexed for inflation;
Account for the full costs of Medicare reimbursements
Anticipate inevitable expenditures for natural disaster relief

text: Obama administration officials predicted that these changes will make the debt over ten years look $2.7 trillion larger than it would otherwise appear.[53]

text: Historical debt levels[edit]

text: Gross federal debt[edit]

text: This table lists the U.S. federal debt as a percentage of gross domestic product, or GDP, each year since World War II.[54] The gross federal debt shown below reached 102.7% of GDP at the end of 2012, the most recent figure available; it was the highest percentage since 1945 and the first yearly percentage figure to go over 100% since then. (The gross federal debt in the table includes intra-government debt – that is, money owed by one branch of the federal government to another. When this latter amount is subtracted, the remaining quantity is known as the public debt.)

text: Gameplay[edit]

text: Similar to the first game, Five Nights at Freddy's 2 is a survival horror video game with point-and-click elements. Players must survive a night shift at Freddy Fazbear's Pizza, a restaurant reminiscent of those like Chuck E. Cheese's and ShowBiz Pizza Place, from 12 A.M. to 6 A.M. game time (approximately seven minutes and six seconds), without being attacked by any of the animatronic enemy characters that wander from room to room. There are multiple different animatronic characters: the original game's antagonists (the titular Freddy Fazbear, Bonnie the Bunny, Chica the Chicken, Foxy the Pirate Fox, and Golden Freddy), as well as upgraded "toy" versions of Freddy, Bonnie, Chica, and Foxy, a marionette referred to as "the Puppet", and a humanoid robot named "Balloon Boy".

text: The player cannot leave the security office, but can track the animatronics' movements via a network of surveillance cameras placed throughout the building. The office has three entrances (a hallway and two side air vents); in a departure from the previous game, none of these can be sealed off to block enemies from entering. Each vent is equipped with a light that can be used to check for any characters that are about to crawl into the office. Players are given a spare animatronic mask to ward off approaching animatronics, however, this strategy will not work on certain characters, who must be repelled by other means. A flashlight is also available, used to check the hallway and darkened areas of the camera feeds, as well as to reset Foxy via strobing. Unlike the previous title, the power supply for the cameras and vent lights is unlimited, but the flashlight does not have an infinite battery life; if it runs out, the player becomes vulnerable to attack. In addition, a music box has been placed in one room and must be remotely wound up through the camera interface, to avoid being attacked by the Puppet, who appears when the music stops. Failure to defend oneself from the animatronics will result in a jumpscare, thus ending the game.

text: Unlike the first game, after the player is killed, there is a chance that rather than the Game Over screen, one of four low-resolution minigames will appear, with instructions given at the start of each. These mini-games contain insight into the plot of the game.

text: The game consists of five levels referred to as "nights", increasing in difficulty. Completing all five unlocks an even more difficult sixth night, which in turn unlocks a "Custom Night" upon completion. In the Custom Night, the player can adjust the AI difficulty of the individual enemy characters or play one of ten pre-set challenges.

text: Plot[edit]

text: Set in 1987, the player character, whose name is later revealed to be Jeremy Fitzgerald, has started working as a night watch security guard at the improved Freddy Fazbear's Pizza.[8] As he did in the previous game, a certain Freddy Fazbear's Pizza employee calls Jeremy on the phone in the office at the beginning of each night to explain both gameplay and parts of the backstory surrounding the restaurant. He explains that the "new" (at the time) animatronics, which have special facial recognition software to protect the children from potential harm, were not programmed with a proper night mode; when things go silent, their programming tells them that they are in the wrong room and they seek out the nearest source of noise to find people to entertain, which happens to be in the office.[9]

text: As in the previous game, the animatronics' programming tells them that there should not be people in the restaurant after hours, so when they encounter Jeremy, they believe he is an animatronic endoskeleton without a costume and stuff him into a spare Freddy Fazbear suit, killing him in the process.[10] The man on the phone explains that this restaurant has an unlimited power source at night, unlike the previous location, but there are no doors blocking access to the office, requiring the player to use a spare Freddy Fazbear mask to trick most animatronics into thinking he is not an endoskeleton; he gives additional tips to help the player survive their shift.[10] As more enemy characters appear as the game progresses, the man on the phone informs Jeremy of the characters' presence, their movement patterns, and some background information on their presence in the game.[11] For example, the man on the phone explains that the older animatronics are in the new restaurant, and have been retrofitted with the new technology, but as they did not work properly they are kept for spare parts.[12]

text: As the game progresses, it is hinted that something is going on during the day, as the man on the phone mentions that rumors are going around and, later, that a police investigation is going on regarding the restaurant. It is hinted in Atari-styled minigames that the restaurant has had a troubled past, as it was apparently the location of a mass murder in which five children were killed by a someone portrayed as a purple-colored man.[13] On the game's fifth night, Jeremy is informed by the man on the phone that the restaurant has been put on lock-down due to an event that he will not describe but which is in place to make sure no employees, present or former, can come in or go out. The man also mentions that the position of the restaurant's day shift security has a vacancy and Jeremy may be promoted to it, and that the owner of the older restaurant named "Fredbear's Family Diner" will be contacted for more information on the animatronics.[14] On the sixth night, the man on the phone informs Jeremy that the restaurant has been shut down for undisclosed reasons, although mentioning the use of a "spare yellow suit" and an issue of the animatronics not functioning properly.[15] He also tells Jeremy that he will be taking over as night shift security guard when the restaurant reopens. If Jeremy is successful in surviving the sixth night, he is promoted to day shift to cover a birthday party on the next day to make sure the animatronics do not cause any problems.

text: In the custom night level, Jeremy is replaced by a new player character named Fritz Smith due to Jeremy's promotion. If the player manages to win the custom night, they discover Fritz has been fired for "tampering with the animatronics" and "odor", a call back to the previous game's custom level message. A newspaper that is shown in the winning screen of the sixth night says that the restaurant will close down and the newer animatronics will be scrapped; however, the older ones will be saved for when the restaurant reopens, hinting at the events of the first game. There is a theory that the scrapping of the toy animatronics and the Bite of 87 are linked in some way.

text: Development[edit]

text: Shortly after the release of Five Nights at Freddy's, developer Cawthon began to confirm rumors of a sequel to the game.[16] Just one month after the original game's release, Cawthon posted a teaser of a sequel on his webpage, and continued to post teasers until the game's release.[17] A trailer for the game was released in October 2014. Five Nights at Freddy's 2 was first released for Microsoft Windows on November 10, 2014, earlier of its planned release of December 25, 2014. Ports for Android and iOS were released on November 13 and November 20 of the same year.

text: Five Nights at Freddy's 2 was met with mixed to positive reviews from critics; the iOS version holds an aggregate score of 75% on GameRankings.

text: Omri Petitte for PC Gamer gave Five Nights at Freddy's 2 a score of 70 out of 100, commenting that what he wanted in the sequel "was more mind games and more uncertainty. I wanted the plodding animatronic suits to find me and rip my face off in new and interesting ways. I wanted working legs. What I got was a horror game dipping heavily into deception and subtlety, a wonderfully cruel cocktail of supernatural mystery and jolts of panicked adrenaline. Enjoying the good parts, though, comes with a cost of a frustratingly steep difficulty."[20] Destructoid also gave the game a positive review, saying that "It's absolutely terrifying to know that you could be attacked at any moment from multiple avenues", praising the introduction of new animatronics and mechanics, but also criticizing the jumpscares and called the game "too hard for its own good".[21]
