Hair-cell current and voltage. A: example hair-cell voltage recorded in current-clamp during sinusoidal mechanical stimuli (Note: mechanical stimuli generate ~0.002 rad of angular hair-bundle deflection for each micrometer of indentation). The resting membrane potential re: endolymph upon entering the cell was near −54 mV (I) and the whole cell resistance was 302 MΩ (pulse). B: same cell at a later time showing the voltage modulation in phase with indentation (II) and the switch from current-clamp to voltage-clamp mode (III). Inward transduction currents are associated with negative deflections of the current trace. Note that the peak receptor potential was nearly in phase (II) re: the mechanical stimulus while the peak current was ~180° out of phase (IV). C and D: example hair-cell responses to step mechanical stimuli in voltage-clamp (C) and current-clamp modes (D).
