1. Bicuculline-sensitive current sharpened the frequency response.
Bicuculline-sensitive current sharpened the frequency response. A, The firing rate of an NM neuron (CF = 1510 Hz) in the control condition (upper panel) and in the presence of bicuculline (lower panel). Dashed lines indicate the spontaneous firing rate and the thin solid horizontal lines indicate the threshold firing level. Arrows indicate the low and high bounds of the sensitive sound frequency. B, The H/L ratio was calculated for the control condition and in the presence of bicuculline. Data from each individual neuron are connected with a line. Black filled circles are data from the neuron shown in A.
