Where this record's text came from. faceted 2026-08 by reading the locally held text (html); every evidence string verified as an exact substring of that text before merging. This is a colloquium review of the author's own monkey single-unit work, so 'review' is the method even though every result discussed is electrophysiological. The Nakamura and Kubota relation is tagged 'extends' as the nearest available type, but the paper's own framing is that its result explains away an apparently contradictory report - none of the four relation types names that move exactly. The review notes that other laboratories found comparable match-nonmatch effects (refs 12-18), but that concerns the author's earlier primary papers rather than this review, so replication status is left untested. TEXT PROVENANCE, 2026-08-15: the text now staged for this record was re-fetched from the PMC article page (PMC33636) on 2026-08-14, 6,189 words. IT IS NOT THE COPY THE TAGS WERE READ FROM. Of the 9 evidence strings on this record, 8 were located verbatim in it and carry anchors; 1 were not, and remain unanchored because the copy they were read from is not held. The one quote that does not resolve cannot resolve against any text: its own spaces were lost when it was recorded ("Repetitionsuppressionappearstobeanintrinsicpropertyof..."), so it is a damaged evidence string, not a missing passage. The comparison covers quoted passages only: it says nothing about the passages we did not quote from. Update, 18 September 2026: the counts above are out of date - today all 84 of this record's quotes are in the staged text and anchored.
4 quotations on this page contain a reference number where the paper printed a superscript. This journal style prints citations as raised numerals — parameters12,13 — and the extraction flattened them into the line, so the sentence reads parameters 12 , 13 . The digits are citation markers and not part of what the author wrote. The quotes keep them for the same reason they keep every other extraction fault: a quote is reproduced exactly or it proves nothing.
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. No tag on this page names a different author. 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.

phenomenonrepetition suppression (neural repetition priming)— “Fig. 1 summarizes in a diagrammatic fashion some of the cortical mechanisms for visual memory that appear to impact on attentional selection processes.”
claim-typemechanism— “All of these mnemonic effects on neuronal responses bias the competitive interactions that take place between stimulus representations in the cortex when there is more than one stimulus in the visual field.”
method — evidence— “We have considered only three short-term memory mechanisms in this brief review, namely repetition suppression, enhancement, and delay activity.”
object of study — evidence— “Recent studies show that neuronal mechanisms for learning and memory both dynamically modulate and permanently alter the representations of visual stimuli in the adult monkey cortex. Three commonly observed neuronal effects in memory-demanding tasks are repetition suppression, enhancement, and delay activity. In repetition suppression…
research question — evidence— “Attention is often thought of as a gateway to learning and memory because we typically learn and remember much more about stimuli in the environment that we attend to than about stimuli we ignore. However, the converse is equally true. That is, mechanisms for learning and memory play a critical role in the selection process that determines…

mechanismTHREE COMMONLY OBSERVED NEURONAL EFFECTS IN MEMORY-DEMANDING TASKS ARE REPETITION SUPPRESSION, ENHANCEMENT, AND DELAY ACTIVITY - repeated experience LEADS TO BOTH SHORT- AND LONG-TERM SUPPRESSION, ENHANCEMENT WORKS IN AN OPPOSITE FASHION for OBJECTS WITH LEARNED BEHAVIORAL RELEVANCE, and delay activity holds information ON-LINE— “Three commonly observed neuronal effects in memory-demanding tasks are repetition suppression, enhancement, and delay activity. In repetition suppression, repeated experience with the same visual stimulus leads to both short- and long-term suppression of neuronal responses in subpopulations of visual neurons. Enhancement works in an opposite…mechanisms[0]
mechanismand they do not share an anatomy: REPETITION SUPPRESSION APPEARS TO BE AN INTRINSIC PROPERTY OF VISUAL CORTICAL AREAS SUCH AS INFERIOR TEMPORAL CORTEX, whereas ENHANCEMENT AND DELAY ACTIVITY MAY DEPEND ON FEEDBACK TO TEMPORAL CORTEX FROM PREFRONTAL CORTEX— “Repetition suppression appears to be an intrinsic property of visual cortical areas such as inferior temporal cortex and is thought to be important for perceptual learning and priming. By contrast, enhancement and delay activity may depend on feedback to temporal cortex from prefrontal cortex and are thought to be important for working…mechanisms[1]
mechanismthe proposed reason suppression happens at all: REPETITION SUPPRESSION IS A BY-PRODUCT OF SHARPENING STIMULUS REPRESENTATIONS IN THE CORTEX - and STIMULUS REPETITION LEADS TO A SMALLER POPULATIONS OF ACTIVATED CELLS— “In this view, repetition suppression is a by-product of sharpening stimulus representations in the cortex. In addition, repetition suppression may contribute to behavioral habituation and, conversely, automatic orientation to novel stimuli (see below).”mechanisms[2]
contradicts studies reporting that IT cells hold a sample stimulus in memory through stimulus-selective maintained delay activity (refs 27-33)— “We found counter-evidence for this idea, however, in our studies using the DMS task with multiple nonmatch test stimuli intervening between the sample and the matching test ( 31 ).”claim_relations[0]
extends Nakamura and Kubota (ref 33)— “This result explains an otherwise contradictory report from Nakamura and Kubota ( 33 ), who found that cells in the anterior and temporal polar regions of IT cortex had stimulus-specific maintained activity in the delays following the sample in a delayed nonmatch-to-sample task.”claim_relations[1]
contradicts the view that attention is the gateway to memory— “Attention is often thought of as a gateway to learning and memory because we typically learn and remember much more about stimuli in the environment that we attend to than about stimuli we ignore. However, the converse is equally true. That is, mechanisms for learning and memory play a critical role in the selection process that determines…claim_relations[2]
critiques the standard delayed matching-to-sample design as evidence for a particular memory mechanism— “In principle, the ABBA task cannot be solved by an animal relying only on the suppressive mechanism, whereas the standard version of the DMS task might be solved by a monkey relying on either enhancement or suppression.”claim_relations[3]

terms this paper carries, each with the sentence it was cut from — the layer that joins one paper to another. Terms with no quote yet are on CONCEPTS.html.
conceptrepetition priming — not defined in this paper's own words; THE BEHAVIOURAL EFFECT, DEFINED BY WHAT IMPROVES: 'experience with an item leads to faster and better performance when subjects are required to name or identify the item at a later time.' Faster AND better - the corpus holds records where it is only one of the two (sivroni2023 finds it in success rates and not response times in mice), so a definition naming both is worth having. Carried on the stub and absent from this record until now.

conceptvisual memory — not defined in this paper's own words; THE PARADIGM IS NAMED IN THE SAME BREATH AS THE CONSTRUCT: 'Most neurophysiological studies of visual memory in primates have used some variation of the delayed matching-to-sample task.' A construct that is, in practice, whatever DMS measures - which is the same operational tie meyer1971 makes between association and the lexical decision task, and the same one Carlesimo2004 makes between implicit memory and what the test instructions do not mention.

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.
