    Frequency discrimination and the spiral ganglion cell population in cats [Abstract]
    Black, Raymond C. ; Steel, A. C. ; Clark, Graeme M. ( 1981)
    Our previous studies on electrical stimulation of the cochlea and auditory nerve have been performed to provide information about cochlear current distributions and electroanatomy, as well as indicating ways of exciting discrete auditory nerve fibre populations to aid in the design of a multiple channel cochlear implant (Black &Clark, 1980). The present study has been carried out to examine the relationship between the size of the spiral ganglion cell population which remains after experimentally-induced graded degeneration of the auditory nerve has occurred and the ability of an animal to perceive certain electrically induced sounds. This is of special interest for a cochlear hearing prosthesis which requires a residual auditory nerve population large enough to adequately relay the electrically induced activity to higher centres.
