Where this record's text came from. faceted 2026-08 by reading the locally held text (xml); every evidence string verified as an exact substring of that text before merging. Claim relations left empty deliberately. The paper cites prior work densely but nowhere positions its own claim against a named study; the one explicit disagreement it reports ("Contrary to the buffer concept, Miller and Cohen propose...") is between two third parties, not between this review and prior work, so recording it would violate the self-relation rule. Claim type is 'existence' rather than 'mechanism' because the review's payload is that these correlates are present in PPC at all, not a causal account of how they arise. Two of the three limitations are limits of the literature the review rests on rather than of a study design, which is the closest a review comes to self-stated limits; the first (scope restricted to LIP and 7a) is a genuine self-limitation. Substantial anatomical-atlas material (areas 5, VIP, 7b, AIP/CIP, LIP, 7a, DP, 7m) and the clinical-lesion section are not captured by any facet. 2026-08-13 and 2026-08-15 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
This record’s own method is review, and the tags below follow from that. A review’s findings, quantities and statistics are things stated IN this paper, and some of them report results obtained elsewhere. 4 tags on this page name the author the result belongs to. Measured across every review in this corpus, 81% of a review’s tags carry no citation at all — most of them are the review speaking. The corpus does not adjudicate the rest: read an unmarked tag as a claim this paper makes, not necessarily one it made first.

phenomenonworking memory and learning in posterior parietal cortex— “More recently, involvement of posterior parietal cortex in other cognitive functions such as working memory and task learning has become evident.”
claim-typeexistence— “These findings demonstrate the importance of posterior parietal cortex in brain networks mediating working memory and learning.”
method — evidence— “We will provide a brief overview of these functions next, and focus on the latter two for the remainder of this review.”
object of study — evidence— “Working memory has traditionally been ascribed to the prefrontal cortex (PFC), but a wealth of recent research demonstrates that posterior parietal cortex is not only activated during working memory, but that inactivation of, or damage to posterior parietal regions can cause specific working memory deficits.”
research question — evidence— “During working memory, posterior parietal neurons continue to discharge and to represent stimuli that are no longer present. This activation resembles the responses of prefrontal neurons, although important differences have been identified in terms of the ability to resist stimulation by distracting stimuli, which is more evident in the…

transferfrom cognitive psychology: Baddeley's four-subsystem model of working memory, imported as the framework for describing what is held and manipulated— “Recent models propose four subsystems of working memory, a “central executive,” responsible for controlling and coordinating information through “slave” systems called the visual-spatial sketchpad for manipulation of visual objects, the phonological loop for verbal rehearsal, and the latest addition, an episodic buffer, that allows for…transfers[0]
transferfrom statistical physics: attractor dynamics, used to describe how a recurrent network holds a state— “Reverberatory networks, when left unperturbed, will settle into an attractor state defined by a stereotyped pattern of activity within the network ( Hopfield, 1982 ). Attractor models may undergo spontaneous oscillations, although network instantiations have also been shown to be capable of mediating sustained responses without oscillatory…transfers[1]
transferfrom clinical neurology: the neglect syndrome, the signature deficit after parietal damage and the original evidence for parietal function— “Perhaps the signature effect of PPC damage is the neglect syndrome, typically occurring after a lesion in the right hemisphere. Disturbances include the inability to detect an object in the contralateral (left) visual hemifield (egocentric neglect) or to perceive the left side of objects, regardless of where they appear within the visual…transfers[2]
mechanismDelay-period activity is sustained because reciprocally connected pyramidal neurons re-excite each other, so discharges keep reverberating around the recurrent circuit after the stimulus is gone.— “Reverberating activity within recurrent circuits is a characteristic of this type of architecture: pyramidal neurons form reciprocal, excitatory connections between them and transmit action potentials to each other so that, even when the original stimulus is no longer present, discharges continue to reverberate in the network.”mechanisms[0]
mechanismSlow postsynaptic receptors (NMDA) keep the postsynaptic cell excited long enough for sparse presynaptic inputs to accumulate, which is what allows low-firing-rate cortical neurons to sustain reverberation.— “Given the fairly low firing rate of cortical pyramidal neurons, postsynaptic receptors with fairly slow time constants are essential for this function.”mechanisms[1]
mechanismDamage to spatial working memory nodes destroys the record of which locations have already been searched, and that failure of book-keeping in the good hemifield compounds the failure to attend to the contralesional one.— “These studies support the idea that when important nodes in the spatial working memory network are compromised or deafferented, an inability to keep track of previously searched locations in the ipsilateral hemifield may contribute to the failure to attend to the contralateral one ( Driver, 2002 ; Malhotra, 2005 ).”mechanisms[2]
mechanismParietal episodic-memory deficits arise because bottom-up processes no longer capture attention toward internally stored memories, so unprompted recall misses details that a top-down cue can still retrieve.— “Episodic memory deficits described in free recall tasks may be attributed to a failure of bottom up processes to capture attention, a phenomenon termed “memory neglect” ( Cabeza, 2008 ; Cabeza, Ciaramelli, Olson, & Moscovitch, 2008 ).”mechanisms[3]
mechanismsustained activity is modelled as reverberation in recurrent excitatory loops that keeps firing after the stimulus is gone— “Reverberating activity within recurrent circuits is a characteristic of this type of architecture: pyramidal neurons form reciprocal, excitatory connections between them and transmit action potentials to each other so that, even when the original stimulus is no longer present, discharges continue to reverberate in the network.”mechanisms[4]
mechanismthe slow NMDA receptor is proposed as the element that lets sparse pyramidal firing sustain itself— “A critical property revealed by models is that discharges can be sustained if the postsynaptic neuron continues to be in an excited state at the time presynaptic inputs accumulate. Given the fairly low firing rate of cortical pyramidal neurons, postsynaptic receptors with fairly slow time constants are essential for this function. The NMDA…mechanisms[5]
mechanismsuch networks settle into attractor states, with or without oscillation depending on the instantiation— “Reverberatory networks, when left unperturbed, will settle into an attractor state defined by a stereotyped pattern of activity within the network ( Hopfield, 1982 ). Attractor models may undergo spontaneous oscillations, although network instantiations have also been shown to be capable of mediating sustained responses without oscillatory…mechanisms[6]
mechanismspiking may not be the only carrier - intracellular and synaptic mechanisms are left open— “These models emphasize the importance of spiking mechanisms as a means for the maintenance of working memory, however it is possible that intracellular and synaptic mechanisms may also play a role”mechanisms[7]

differs inattempts to map Baddeley's working memory subsystems onto brain regions — THE AXIS IS FUNCTIONAL VERSUS ANATOMICAL INDIVIDUATION. 'these working memory subsystems refer to functional rather than anatomical units ... For example, the prefrontal cortex seems a logical functional neural analogue to the central executive. However, physiological evidence indicates that prefrontal neurons in area 46 represent spatial and ob[ject information].' The mapping from a model component to a brain region is denied as an identity while kept as an analogy.

Statistics — cross-field join keys
field-invariant statistical terms, used in their statistical sense (gated on a number / symbol / test). A p-value or a standard deviation means the SAME thing in physics, biology, psychology and sociology — so these are the strongest cross-field join keys. Grounded verbatim.

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
