Figure 13. (A) Cochleogram from a chinchilla treated with a high dose (50 mg/kg) of carboplatin. (B) IC input/output function at 500 Hz obtained pre-carboplatin and at 3 days, 2 2weeks and 5 weeks postcarboplatin. Note lack of amplitude reduction. (C) AC input/output function at 500 Hz obtained 3 days, 2 weeks and 5 weeks post-carboplatin. Note increase in AC amplitude at levels above 40 dB SPL at 2 weeks and 5 weeks post-carboplatin.
