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. The Benda (2002) relation is included as 'builds-on' because the paper does not merely cite it but uses the quantitative receptor adaptation ratio as a component of the prediction its own data are tested against ('Our data were compared with this relation.'). The paper's own core claim — that the origin of adaptation is cell-type and function specific — is new here, so replication status is 'untested'; only its transfer-function measurements are said to match earlier reports. 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.
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.
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 WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below.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, 1 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.
SFA TN1 BSN1 AN2 receptor acoustic stimulation current stimulation adaptation ratio time constant afterhyperpolarization inhibitory inputs spontaneous activity rate coefficient gain function high-pass low-pass RAM encoder adaptation transducer adaptation metathoracic ganglion spike initiating zone recording site In AN2 each spike triggers a slowly decaying afterhyperpolarizing current; during a stimulus these afterhyperpolarizations accumulate, progressively lowering excitability and thereby producing the adaptation. In AN2 the responsible conductance is inferred to be a spike-triggered AHP- or M-type current rather than a network effect. In BSN1 the hyperpolarization is not generated by the cell's own spikes but is imposed by presynaptic inhibitory input driving slow hyperpolarizing currents. A functional design rule: when a neuron's computation depends on the balance of incoming excitation and inhibition, adaptation must sit in the neuron itself rather than in its inputs, so that the balance is preserved. spike frequency adaptation (SFA) stimulation mode stimulus intensity cell type hyperpolarization onset spike frequency Wilcoxon rank-sum test Wilcoxon ranks sum test p-value correlation coefficient linear regression Regression coefficients for linear fits nonlinear (exponential) curve fitting with model comparison double exponential fits did not significantly improve the fit quality goodness-of-fit threshold for inclusion mean and standard deviation standard error of the mean propagation of error Propagated errors were calculated by partial differentiation linear interpolation derived from linear interpolations spectral (gain function) analysis the gain functions were calculated regression coefficient electrophysiology

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.4800-08.2009. 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 9 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

about this quote: This quote ends on 'by' because what it introduces is a displayed formula that the staged extraction does not carry as readable text (the text continues: "r a ( I ref ) = f ss ( I ref )/ f on ref . Propa"). The quote is verbatim and the formula is in the paper; the quote was not extended, because extending it would put extraction debris inside a quotation.
