Fig. 3. Impaired prestin activity in Myh1−/− mouse outer hair cells.

Fig. 3

a Input voltage-clamp pulse protocol used for stimulating prestin in the outer hair cells. A 1 kHz sine wave with a 10 mV amplitude was simultaneously applied at −150 to 100 mV for a 250 ms duration. b, c Representative traces of Myh1+/+ and Myh1−/− mouse outer hair cell recordings at postnatal Day 21. d Voltage-normalized nonlinear capacitance (NLC) relationship of Myh1+/+ (n = 6) and Myh1−/− (n = 8) mouse outer hair cells. The bell-shaped curve was fit to the derivative of the Boltzmann equation. e Vh values calculated from the outer hair cells of Myh1+/+ and Myh1−/− mice. f Normalized charge transfer density calculated from the outer hair cells of Myh1+/+ and Myh1−/− mice. Data are presented as the means ± SEMs. Statistical comparisons were performed using two-sample independent t-tests in (e) and (f). *P < 0.05 and **P < 0.01.
