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. Replication status is 'contested' because the paper's own auditory-cortex maintenance-activation finding directly opposes Linke et al. (2011) (suppression) while matching Linke and Cusack (2015) (activation), and the paper describes the hippocampal role in working memory as controversial. Claim type is 'mechanism' rather than 'existence' because the contribution is the proposed circuit account (long-range connectivity from hippocampus and IFG keeping auditory-cortical representations active), not merely that AWM activity exists. 2026-08-13, 2026-08-14, 2026-08-15 and 2026-08-25 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.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. 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 WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below.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 An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason.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.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 22 concept tags on this paper, 2 are grounded in a quoted sentence. All carry the tagger's gloss of what the term means in this paper, which is not something the article can license.

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.1523/jneurosci.4341-14.2016. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 8 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above.
RETRACTED: TWO EFFECTS OF A COMMON CAUSE, TAGGED AS CAUSING EACH OTHER - a class I have not named before. The edge is 'hippocampus --causes--> behavioral performance'. The span is a chain of PREDICTIONS: '…on LTM, and, THEREFORE, hippocampus WOULD BE ACTIVATED…'. The upstream cause is failure to sustain attention, which produces LTM reliance; LTM reliance produces BOTH greater hippocampal activation AND poor performance. Hippocampal activation is a MARKER of the same upstream process, not a cause of the performance. Reading the two consequences as one causing the other is the classic confound, and here the paper itself lays the structure out. WHAT THE SPAN DOES SAY: housed below as the common-cause structure, since no type can record 'these two share a cause'. — strength of the relation: 0.6 — the record marks this weak · note: SIGN NEGATIVE, AND PREDICTED IN ADVANCE FROM THE RIVAL'S MODEL: more hippocampal activity should mean worse performance if it reflects falling back on long-term memory Audit 2026-09-28: DOUBTFUL - read against its span and kept, but the span states a prediction; causes states it as a finding.

WHOSE RESULT THIS IS: Serences et al., 2009 ; Riggall and Postle, 2012 ) have shown - THE EVIDENCE FOR THIS ROW ATTRIBUTES THE WORK TO SOMEBODY ELSE. The cited name is the subject of a result verb and the sentence carries no first-person marker, so the finding, quantity or definition is the CITED author's rather than this record's. The claim is true and the quote is verbatim - what is wrong is whose result the corpus says it is. Nothing edited, nothing withdrawn: the row is marked so a page can name the source. Where the record is a commentary or review, its claim relations layer usually already names the paper being discussed - the record knows at one layer and forgets at another.

What was deliberately not tagged, and why, is recorded per paper by the tagger. Where a paper has no such record, this page says so rather than implying that nothing was declined.
