FIG. 1.

Depolarization of both rostral (A) and caudal (B) AP hair cells elicited inward currents and concomitant changes in capacitance. The top traces represent the hair cell’s command voltage (V_c). The brief depolarization (100 ms) elicited an inward current (I_m). The cell’s capacitance (C_m) and series resistance (R_s) are shown before and after depolarization. The change in capacitance (ΔC_m) was calculated as the difference between the mean capacitance (dashed lines) before and after depolarization of the cell. The time brackets underneath the command-voltage trace indicate the time windows over which the mean capacitance before and after the depolarizing step were calculated. I_m traces have been leak subtracted.
