Jitter improves ITD sensitivity at high pulse rates for snappy neurons. A and B: percentage of neurons sensitive to ITD as a function of mean pulse rate for periodic (black) and jittered (gray) stimuli. C and D: ITD STVR (mean ± SE) as a function of mean pulse rate. Jitter significantly improved the ITD sensitivity of snappy neurons to pulse rates ≥320 pps. E and F: ITD STVR (mean ± SE) limited to responses for which the maximum firing rate was >5 spikes/s. For the handful of snappy neurons responsive to high-rate periodic pulse trains, ITD sensitivity was equal to that produced by high-rate jittered stimuli.
