Abstract
The peripheral representation of sounds is transmitted by the auditory nerve to intermediate stages of the nervous system, preceding identification. We suppose that main features of sounds corresponding to perceptual dimensions like pitch and timbre are already extracted in these levels, complementing richer and extensive representations localised in cortical areas. This approach allows us to consider a biological system having a rather simple architecture, known inputs and outputs. Understanding physiology allows us to perform auditory scene analysis (ASA) grounded on plausible basis. ASA is an emerging concept integrating particular properties of the auditory system working together in order to deal with a complex environment (Bregman, 1990). From the neurobiological point of view, the goals of such a modelling work are: (1) better approaching the way of coding and controlling information in the nervous system, (2) comparing with physiological data, and finally (3) reducing the computational processes.
