ITDenv tuning for the standard BMB stimulus (pulse rate = 1,000 pps, fmod = 40 Hz) across the population of ITDenv-sensitive IC neurons. A and B: normalized ITDenv functions for all neurons tested (1 trace per neuron) with the standard BMB stimulus. Peak-shaped tuning is shown in A and trough-shaped tuning in B. Responses are scaled and shifted along both axes to show the goodness of fit of the positive and negative Gaussians to the data. C–G: distributions of vector strength, best IPDenv, ITDenv half-width, maximum slope of ITDenv tuning, and neural ITDenv just noticeable differences (JNDs) for neurons with peak- and trough-shaped ITDenv tuning. G: single-unit neural ITDenv JNDs (from a reference of 0 ms) were measured in 31 of 33 neurons. The remaining 2 neurons with unmeasurable JNDs are shown to the right of the distributions.
