Abstract

A great deal is now known about the neural coding of sound by the auditory periphery. Perhaps the most crucial process for this coding is frequency selectivity or tuning. However, other processes must often be considered when describing the form of the neural code provided to the central nervous system. This paper describes one of these processes--lateral inhibition--and its role in modifying the spectral information contained in some complex sounds.
