The favoured synchrony account rests on very little direct empirical evaluation. Quotation withheld because this record is not cleared for redistribution. Neither of the two surviving models has been subjected to a decisive set of tests, and the competing Bayesian account also has support. Quotation withheld because this record is not cleared for redistribution. The proposed MEG/ECoG evidence cannot be tied to repetition suppression, because field-activity measures have no established relation to overall activity level. Quotation withheld because this record is not cleared for redistribution. In the reply the authors concede that the Discussion Paper failed to make clear that the four models are not mutually exclusive. Quotation withheld because this record is not cleared for redistribution. a CONTROL CONDITION against which spike-LFP coherence in the gamma range (30-80 Hz) was measured after adaptation eliminates: that the change in synchronisation is a general property of the recording rather than an effect of stimulus repetition · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. the extreme form of the Explaining Away account was tested against the observed pattern of repetition suppression eliminates: that ALL repetition suppression is high-level repetition expectation - the extreme version makes a prediction the data do not bear out · outcome (stated by the tagger, no quotation): held Quotation withheld because this record is not cleared for redistribution. repetition suppression repetition suppression Quotation withheld because this record is not cleared for redistribution. neural synchronization neural synchronization Quotation withheld because this record is not cleared for redistribution. efficiency efficiency Quotation withheld because this record is not cleared for redistribution. sharpening sharpening Quotation withheld because this record is not cleared for redistribution.

Predictive Coding Predictive Coding Quotation withheld because this record is not cleared for redistribution. Explaining Away → Predictive Coding A NAMING DISPUTE BETWEEN AUTHORS IN ONE EXCHANGE, AND NO TYPE HOLDS IT. 'Ewbank and Henson appear…' Two labels, one model, and the disagreement is printed rather than reconstructed. 'renamed-across-fields' is the nearest type and it is wrong twice over: this is not across FIELDS and not a RENAME - both names are in current use by different authors in the same journal exchange, and neither replaced the other. 'same-as' asserts an equivalence the disputants would both reject as missing the point, since the whole argument is about what the name must EXCLUDE ('from the variety…'). THE GATE REFUSED IT FOR A DIFFERENT REASON AND THE REFUSAL WAS STILL RIGHT: 'RENAMING' has 'called / known as / termed / referred to as / the term / nomenclature' and not 'label'. I measured 'label' as a candidate cue before proposing it - 2 occurrences in renamed-across-fields edges against 65 in other edges, a 1.28% base rate, against the ~0.00% the list's existing extensions were held to. Adding it would admit 65 edges that are not renamings. Fifth missing relation type of the session, after is-an-aspect-of, a-claim-about-a-usage, is-a-defining-condition-of and prerequisite-for. the project, 2026-08-27. Quotation withheld because this record is not cleared for redistribution. THE PUZZLE, STATED AS A PUZZLE, WHICH IS WHY THIS RECORD IS WORTH HAVING: `How is it that reductions in neural activity can mediate better behavioral performance?` The corpus now holds four positions on that question, all merged today and none of them citing another in this set: Desimone1996 calls suppression `an intrinsic property of visual cortical areas`; Carlesimo2004 reads an rCBF decrease as `the reduced neural activity needed to reprocess recently seen words`; mcmahon-olson2007 concludes suppression `ACCOMPANIES repetition priming but is UNLIKELY TO BE ITS CAUSE`; and this paper says the puzzle is real and rate is the wrong variable Quotation withheld because this record is not cleared for redistribution. AND THE ANSWER IS A REPLY TO McMAHON AND OLSON RATHER THAN A CONTRADICTION OF THEM. `as cells are firing at lower overall rates, they are firing more synchronously with one another, leading to more efficient neural processing` - and in simulation, `as the model's firing rates decreased with repetition, the synchronization of the spike times simultaneously increased.` Both papers agree the rate drop is not the mechanism. They differ on whether anything else in the same signal is: McMahon and Olson tested rate and selectivity and found neither sufficient; Gotts proposes a variable neither of them measured Quotation withheld because this record is not cleared for redistribution. IT NAMES THE GAP IN ITS OWN EVIDENCE, WHICH A PROPOSAL PAPER USUALLY DOES NOT: `despite exciting recent work on the role of neural synchronization in cognitive processes such as attention and perception, similar studies in the domain of learning and memory - and priming, in particular - have been LACKING.` The mechanism is offered together with the statement that the direct evidence for it has not been collected in this domain. Compare meyer1971's `At present we do not have ways to test all the possible explanations of these effects` - forty-one years apart, the same willingness to write the limitation flat Quotation withheld because this record is not cleared for redistribution. `sharpening` - A NAMED ACCOUNT WHOSE NAME ENCODES ITS MECHANISM: `A second idea, often referred to as “sharpening” (Desimone, 1996; Wiggs & Martin, 1998), holds that while neural activity is decreasing on the average, the decreases are carried mainly by the cells that are poorly tuned and/or weakly responsive ... with the “best” cells ... instead retaining their activity levels.` THE WORD IS THE HYPOTHESIS: a population response gets NARROWER, not smaller, and the mean decrease that `repetition suppression` names is a side effect of that narrowing. Two names for one measurement, differing in what they say caused it. Quotation withheld because this record is not cleared for redistribution. `priming` NARROWED BY STIPULATION - BUT NOT BY THIS PAPER'S AUTHORS: `the complex relationship between repetition suppression (RS) and behavioral priming (henceforth referred to as priming)`. VOICE: this sentence is from a PEER COMMENTARY printed with the article, not from Gotts, Chow and Martin - it opens `Gotts et al. present four neural models` and continues `I strongly support Gotts et al.'s call`. So the stipulation binds the COMMENTATOR's text, and a reader who takes it as the target article's own definition has attributed a narrowing to the wrong authors. Quotation withheld because this record is not cleared for redistribution. `Explaining Away` / `Predictive Coding` - THE SAME MODEL, TWO LABELS, AND THE DISAGREEMENT IS PRINTED. `Ewbank and Henson appear to take issue with our use of the label “Explaining Away” when referring to Friston's Bayesian model, preferring instead “Predictive Coding”.` This is a naming dispute conducted in the literature rather than reconstructed from it - commentators object, authors answer, and both names go on being used. The authors' stated rationale is DISCRIMINATION: a label that separates the anti-symmetrical property from `the variety of models that utilize prediction in very different ways`. Neither party thinks the model is in doubt; they disagree about what the name must exclude.

A corpus joining two papers on `priming` may be joining a 200-millisecond effect to one lasting a year, and nothing in either paper's use of the word records which.

'firing MORE SYNCHRONOUSLY…' - the verb is explicit and both endpoints are named. Weight 0.9 because the span opens 'A very different…': the hedge is the authors' and it is inside the quote. The edge is real and the thing it connects to behaviour is a word, not a number - nothing in this paper measures efficiency directly, and the same sentence is where the account stops being physiological and starts being functional.
