Responses of auditory-nerve fibers were studied in cats exposed to acoustic trauma. Four synthetic steady-state vowels were used as test signals; these stimuli are identical, except that the second formant (F2) resonator in the synthesizer was set to 1.4, 1.5, 1.7, or 2 kHz, producing four spectra that differ mainly in the vicinity of the F2 frequency. These stimuli were presented to a large population (523) of auditory-nerve fibers in four cats with sloping high-frequency threshold shifts that reached 50\u201370 dB at 2\u20134 kHz. In normal animals, [Auditory Neurosci. 3, 135\u2013162 (1996)] showed previously that the discharge rates of fibers with best frequencies near the F2 frequencies provide enough information to allow discrimination of these stimuli at the performance levels shown by cats in behavioral experiments. Here it is shown that, after acoustic trauma, there is essentially no rate information which would allow the vowels with different F2 frequencies to be discriminated. However, information that could allow discrimination remains in the temporal (phase-locked) aspects of the responses.<\/jats:p>","DOI":"10.1121\/1.424552","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T14:06:16Z","timestamp":1027692376000},"page":"311-325","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":20,"title":["Discriminability of vowel representations in cat auditory-nerve fibers after acoustic trauma"],"prefix":"10.1121","volume":"105","author":[{"given":"Roger L.","family":"Miller","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering and Center for Hearing Sciences, Johns Hopkins University, Baltimore, Maryland\u200921205"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara M.","family":"Calhoun","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering and Center for Hearing Sciences, Johns Hopkins University, Baltimore, Maryland\u200921205"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric D.","family":"Young","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering and Center for Hearing Sciences, Johns Hopkins University, Baltimore, Maryland\u200921205"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023071405143728600_cal"},{"key":"2023071405143728600_con","doi-asserted-by":"crossref","first-page":"3223","DOI":"10.1121\/1.413812","article-title":"Rate representation and discriminability of second formant frequencies for \/\u025b\/-like steady-state vowels in cat auditory nerve","volume":"98","year":"1995","journal-title":"J.
