This multi-disciplinary research showed sound could be coded by electrical stimulation of the cochlea and peripheral auditory nervous system. But the temporal coding of frequency as seen in the experimental animal, was inadequate for the important speech frequencies. The data indicated the limitation was due in particular to deterministic firing of neurons and failure to reproduce the normal fine temporo-spatial pattern of neural responses seen with sound. However, the data also showed the need for the place coding of frequency, and this meant multi-electrodes inserted into the cochlea. Nevertheless, before this was evaluated on people we undertook biological safety studies to determine the ..View full abstract
