A key question that arises from these experiments is: What effect does a reduction in IHC-eighth-nerve fiber input have on the central auditory nervous system? This investigation evaluated the inferior colliculus potential (ICP) in chinchillas treated with carboplatin. The left ear was surgically destroyed and a recording electrode was placed in the left inferior colliculus. Following thirteen days of recovery time, the ICP was recorded in the awake animal. Click level was varied from 10\u201320 to 80 dB pSPL. Click rate was varied from 10 to 1000 Hz using both conventional averaging and a cross-correlation procedure. Broadband masking noise was varied from 30 to 70 dB SPL with click level held constant at 80 dB pSPL. The dependent variables were the positive peak latency and peak-to-following trough amplitude of the evoked potential. Following baseline studies, the animals were administered carboplatin (50 mg\/kg IP) and retested two weeks later. Prior to carboplatin administration, there was an increase in ICP latency and a decrease in ICP amplitude with decreasing stimulus level, increasing rate and increasing noise level. Mean ICP threshold was 30 dB pSPL. Following carboplatin administration, there was little change in threshold or peak latencies. In contrast, the amplitude of the ICP was reduced on average by one-third, although this effect varied considerably across animals. The magnitude of this amplitude decrement was not strongly dependent on click level, click rate, or the level of background noise.<\/jats:p>","DOI":"10.1121\/1.420149","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T14:03:47Z","timestamp":1027692227000},"page":"3620-3627","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":24,"title":["The effects of click level, click rate, and level of background masking noise on the inferior colliculus potential (ICP) in the normal and carboplatin-treated chinchilla"],"prefix":"10.1121","volume":"102","author":[{"given":"Robert","family":"Burkard","sequence":"first","affiliation":[{"name":"Center for Hearing & Deafness, 215 Parker Hall, SUNY\u2014Buffalo, Buffalo, New York 14214-3007"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Trautwein","sequence":"additional","affiliation":[{"name":"Center for Hearing & Deafness, 215 Parker Hall, SUNY\u2014Buffalo, Buffalo, New York 14214-3007"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Salvi","sequence":"additional","affiliation":[{"name":"Center for Hearing & Deafness, 215 Parker Hall, SUNY\u2014Buffalo, Buffalo, New York 14214-3007"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023070917310910700_bro89","doi-asserted-by":"crossref","first-page":"143","DOI":"10.1016\/0378-5955(89)90140-8","article-title":"Acoustic distortion products can be used to monitor the effects of chronic gentamicin treatment","volume":"42","year":"1989","journal-title":"Hearing Res."},{"key":"2023070917310910700_bur94a"},{"key":"2023070917310910700_bur94b","doi-asserted-by":"crossref","first-page":"2126","DOI":"10.1121\/1.408674","article-title":"Gerbil brainstem auditory evoked responses (BAERs) to maximum length sequences","volume":"95","year":"1994","journal-title":"J.
