Amplitude modulation in the stellate microcircuit of the cochlear nucleus

Abstract

This paper presents the amplitude modulated coding behaviour in a biophysically-realistic neural network model of the cochlear nucleus. It focuses specifically on the microcircuit of T stellate cells, with three inhibitory interneurons. T stellate cells provide a robust spectral representation of auditory information, and enhanced coding of temporal information (especially the pitch in complex environments [1]). The model contains three inhibitory interneurons, each controlling the rate and temporal response of T stellate cells. Despite saturation of their characteristic frequency, the ability to code temporal information is not disabled. The optimal coding of amplitude modulation is still p..
