Abstract

A pseudo-inverse technique has been applied to a lumped-element model of the first turn of an implanted cochlea of a guinea pig. The method calculates the currents necessary to focus or distribute stimuli in desired patterns across the location of the family of auditory nerve cells in the implanted ear. Studies in animals are being undertaken to validate the technique.
