Abstract

Recent experiments show that many of the interaural time difference (ITD) sensitive neurons in the inferior colliculus (IC) respond differently to stimuli with constant or dynamically varying ITDs. We have developed a firing rate model with an activity-dependent adaptation mechanism to study these plasticity effects. The model is highly idealized, which makes it tractable and allows clear interpretation. In our formulation, the dynamic effects originate in the IC and are not inherited from the lower level structures. The results are in a good qualitative agreement with experimental data.
