In this region the hair\u2010cell stereocilia are free\u2010standing, i.e. they protrude directly into endolymph and are not in contact with a tectorial membrane. The frequency selectivity of hair\u2010cell responses was measured by means of isovoltage contours of the d.c. (V0) and fundamental\u2010a.c. (V1) component of the receptor potential, i.e. iso\u2010V0 and iso\u2010V1 contours. The frequency selectivity of the nerve\u2010fibre discharge was measured by iso\u2010rate (iso\u2010V0) contours. Iso\u2010V0, iso\u2010V1 and iso\u2010V0 contours are basically V\u2010shaped with a characteristic frequency (c.f.) defined as the frequency at which minimum sound pressure (Pmin) is required to evoke the criterion value of the response. Receptor potential iso\u2010V0 contours and neural iso\u2010V0 contours have similar slopes: the mean slopes of the low\u2010frequency sides (dB\/decade) are \u201043.0 and \u201044.3; the slopes of the high\u2010frequency sides are 85.0 and 80.2. The band widths of iso\u2010V0 and iso\u2010V0 contours away from c.f. are similar (mean values of Q30dB are 0.40 and 0.53, respectively). The band widths of iso\u2010V0 contours near c.f. are narrower than those of iso\u2010V0 contours (mean values of Q10dB are 2.34 and 1.20, respectively). However, the shapes of the contours near c.f. depend on the iso\u2010response criteria, and we have not determined whether or not iso\u2010V0 and iso\u2010V0 contours are similar near c.f. The shapes of iso\u2010V1 contours differ from those of iso\u2010V0 and iso\u2010V0 contours. Nerve fibre c.f.s are tonotopically organized in the nerve, with lowest c.f.s recorded from fibres innervating the border of free\u2010standing and tectorial regions, a region in which hair\u2010cell stereocilia are longest, and the highest c.f.s recorded from fibres innervating the end of the free\u2010standing region in which hair\u2010cell stereocilia are shortest. The c.f. of nerve\u2010fibre response (and by implication hair\u2010cell response) is, therefore, correlated with the height of the stereociliary tuft. The shapes of iso\u2010V0 contours vary systematically with c.f. and, therefore, tonotopically with nerve position.(ABSTRACT TRUNCATED AT 400 WORDS)<\/jats:p>","DOI":"10.1113\/jphysiol.1983.sp014976","type":"journal-article","created":{"date-parts":[[2014,12,19]],"date-time":"2014-12-19T06:53:21Z","timestamp":1418972001000},"page":"241-260","source":"Crossref","is-referenced-by-count":51,"title":["Frequency selectivity of hair cells and nerve fibres in the alligator lizard cochlea."],"prefix":"10.1113","volume":"345","author":[{"given":"T","family":"Holton","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T F","family":"Weiss","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1983,12]]},"container-title":["The Journal of Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1113%2Fjphysiol.1983.sp014976","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/pdf\/10.1113\/jphysiol.1983.sp014976","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T08:39:32Z","timestamp":1697791172000},"score":1,"resource":{"primary":{"URL":"https:\/\/physoc.onlinelibrary.wiley.com\/doi\/10.1113\/jphysiol.1983.sp014976"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1983,12]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1983,12]]}},"alternative-id":["10.1113\/jphysiol.1983.sp014976"],"URL":"https:\/\/doi.org\/10.1113\/jphysiol.1983.sp014976","archive":["Portico"],"relation":{},"ISSN":["0022-3751","1469-7793"],"issn-type":[{"value":"0022-3751","type":"print"},{"value":"1469-7793","type":"electronic"}],"subject":[],"published":{"date-parts":[[1983,12]]}}}
