The input-output functions of ABR responses (wave 1 amplitudes at 10 and 16 kHz) in ABT-702-treated and control vehicle-treated C57BL/6J mice (early and late treatments). Only those data where a repeatable wave 1 could be measured above the noise floor were plotted. Baseline wave 1 amplitudes measured before the start of ABT-702 or vehicle treatment were similar between the groups at 3 months (A,C) and at 6 months of age (E,G). At 9 months, suprathreshold amplitudes of ABR wave 1 increased in ABT-702-treated mice at 10 kHz (B,F) and 16 kHz (D,H). Data are expressed as means ± SD (n = 8); *P < 0.05.
