Figure 3.
Effects of spectral shape on discharge rates in the inferior colliculus (IC). A. Responses of a representative type III neuron to 99 HRTF-shaped noise bursts. Driven rates are plotted relative to stimulus level at BF (13.6 kHz). Replications at different attenuation settings are distinguished by symbol type. B. Same plotting format showing the rate-level relationships of a population of IC neurons (N = 160 units).
