Effects of 1 mm 4-AP and 6 mm TEA on current-clamp recordings from enzymatically dissociated hair cells. A, Resonance recorded in normal extracellular solution (control:I_stim = 200 pA; f = 225 Hz; V_rest = −72 mV) was not affected by 4-AP. B, TEA reversibly eliminated resonance (control, solid line: I_stim = 200 pA; f = 222 Hz;V_rest = −52 mV). Oscillations recovered fully when TEA was removed (recovery, dotted line). Both recordings were made using perforated patch. The records inA are the average of five presentations.
