Abstract:
1. A method for simultaneously activating electrodes in a multi-channel electrode array of a cochlear implant having a monopolar electrode configuration, the method comprising: determining, in a processor, a desired potential for a given position relative to the electrode array; after determining, in a processor, the desired potential, calculating, in a processor, amplitudes of simultaneous, sign-correlated pulses associated with at least two electrodes of the multi-channel array by adding resulting potentials from each of the sign-correlated pulses at the given position, so as to provide a total potential at the given position substantially equal to the desired potential; and after calculating, in a processor, the amplitudes, simultaneously activating the at least two electrodes as a function of the calculated amplitudes to achieve the desired potential at the given position so as to stimulate the acoustic nerve, wherein the at least two electrodes have spatial channel interaction when activated.
