    Abstract
    Multiple-channel auditory prostheses provide both temporal and formant information to profoundly-totally deaf patients. This is achieved via direct electrical stimulation of selective regions of the residual auditory nerve using an electrode array located in the scala tympani. Histological evidence has shown that these electrode arrays lie along the outer wall of the scala tympani, some distance from the residual nerve elements. In the present study we systematically varied the position of the electrode array within the cat scala tympani in order to investigate the influence of electrode position on neural excitation. Such knowledge may contribute to the development of improved electrode arrays for auditory prostheses.
