Firing rate does not encode differences between natural and disrupted calls. A: experiment 1. Firing rate index as a function of stimulus condition for all tested cells. Firing rate index for each call was calculated relative to the response for the natural aggression call. Black line denotes the population mean; n = 24. B: experiment 2. Firing rate index as a function of reversal length for all tested cells. Firing rate index was calculated as (FR_rev − FR_nat)/(FR_rev + FR_nat), where FR_nat is the average firing rate for the natural call and FR_rev is the firing rate for the locally time-reversed call. Each data point corresponds to one cell. Black line denotes the population mean; n = 37.
