    Chronic electrical stimulation of the auditory nerve at high stimulus rates: preliminary results
    Shepherd, R. K. ; Xu, J. ; Millard, R. E. ; Clark, Graeme M. ( 1994)
    The present preliminary report describes the electrophysiological response of the cochlea during long-term stimulation. The data indicate that electrical stimulation at a rate of 1000 pulses per second does not appear to adversely affect the implanted cochlea.

    Behavioral thresholds in the cat to frequency modulated sound and electrical stimulation of the auditory nerve
    Clark, Graeme M. ; Kranz, Howard G. ; Minas, Harry ( 1973)
    This behavioral study has helped confirm that cats can perceive low rates of electrical stimulation of the basal or high frequency end of the cochlea. The upper limit on the rate of stimulation that could be perceived was 600-800 pulse/sec. It was also shown that the behavioral threshold for low rates of change of a frequency modulated electrical stimulus was similar to that of sound. In the case of an electrical stimulus it was 85 pulses/sec/sec. and in the case of sound it was 97 cycles/sec/sec.
