• Abstract:A comprehensive human auditory neural pathway spiking (HANPS) model from cochlea to inferior colliculus is proposed in this paper. It consists of medial superior olive (MSO) pathway for interaural time difference processing, lateral superior olive (LSO) pathway for interaural level difference processing, and the inferior colliculus (IC) module which integrates results. Architecture and design are provided which is strictly based on the physiological organization of human auditory pathway. The MSO and LSO pathway are both designed in a biological plausible way by using all neuron and no mathematical functions. Traditional binaural probabilistic model for localization is applied to the IC module in a Bayesian way. Quantities ofsimulations are conducted, analyzed which demonstrates the good ability to extract the localization cues and ability to integrate them, thus the ability to localize. Moreover, good ability to distinguish different sounds is also shown by simulation with multiple sound input. A brain-like circuits structure for the proposed HANPS model and some designing requirements are suggested.
