Discharge rate distributions for spontaneous activity and DPT-evoked responses. The black vertical bars represent a histogram (bin width 2.5 spikes/s) of the discharge rates in response to the DPT. For each unit, the discharge rate was averaged from 100 to 130 s after stimulus onset. Only responses to the DPT presented at the standard level in each animal (Table I) are included, and each ANF is included only once, even if multiple data records are available. The black line shows the cumulative distribution of discharge rates to the DPT. The dashed line shows the cumulative distribution of spontaneous discharge rates from four healthy ears (Liberman, 1990).
