Abstract :
This paper describes a computational model of the cochlea with the appropriate interface for a cochlear prosthesis. This interface consists of two parts. First neural activity is mapped to electrical current density at the neurons. Then the optimal stimulation pattern is derived through a least squares fit, given the current spread function between the electrodes and the nerve endings. Practical limitations which limit the usage of this scheme, as well as the first tests performed with our patients, are described.
