A Model for Duration Coding in the Inferior Colliculus

  • Chapter

Abstract

We have implemented a biophysically-plausible model of duration-sensitive cells in the inferior colliculus which process the output of an auditory nerve model using temporal interactions between excitation and inhibition. Duration tuning results from temporal coincidences between an offset response and a delayed onset response. Model cells tuned to a range of best durations were tested with signals having durations between 2 ms and 40 ms. The model accurately simulated the duration tuning seen in the physiological data of Casseday et al. (1994) and also successfully simulated the effects of inhibitory blockers.
