Responses of phenomenological model to various ITD stimuli. A: temporal response patterns for constant-amplitude pulse trains as a function of pulse rate. All stimuli are 300 ms in duration, the peak intensity is 1 dB re model threshold, and the ITD equals the model neuron’s internal delay (ITDbest). The bottom trace shows the effect of 40-Hz AM on the response to a 1,000-pps pulse train. B: ITDenv tuning for a 1,000-pps AM stimulus at 3 modulation frequencies (1 dB re threshold). C: ITDenv half-width decreases with increasing modulation frequency. D: ITDenv tuning for a 1,000-pps, 80-Hz AM stimulus at 3 stimulus intensities (dB re threshold). E: ITDenv half-width increases with increasing intensity. F: model ITDwav tuning for 1,000-pps, 40-Hz AM stimulus (top) and 5,000-pps, 40-Hz AM stimulus (bottom) at 1 dB re threshold.
