Scatter plots of spontaneous firing of hyperactive CNIC neurons with electrical stimulation of the OCB (gray bar), showing examples of short (ranging from 100 to 400 ms) suppression of spontaneous rate followed by a return to baseline spontaneous rate levels. A, Neuron CF 28 kHz, threshold 60 dB SPL. B, Neuron CF 6 kHz, threshold 22 dB SPL. C, Neuron CF 7.8 kHz, threshold 17 dB SPL. Stimulation parameters: 100 ms duration, 0.1 ms pulses, 300 Hz. Stimulation strength in A and B was 250 μA and in C 400 μA.
