Contralateral Suppression of DPOAEs in Mice after Ouabain Treatment

Figure 1

Ouabain treatment did not significantly alter contralateral suppression. (a) The time course of contralateral suppression showed no significant difference between the control and ouabain-treated groups. , data were shown as the mean ± SEM. (b) The amplitude of the peak suppression of the control and ouabain-treated groups. Fifteen seconds of 76 dB SPL. 13–20 kHz noise produced a similar reduction in the amplitude of the 2f₁−f₂ DPOAE (60 dB SPL 16 kHz) in the control and ouabain-treated ears. Data in (b) showed the amplitude of the peak suppression which is from the first measurement after noise onset relative to the average of the prenoise baseline. , the boundaries indicated 25th and 75th percentile; solid line indicated median; error bars indicated the maximum and minimum.
