ItemA hearing prosthesis for severe perceptive deafness: experimental studies(Cambridge University Press, 1973)In the last few decades advances in science and surgery have permitted man to repair or replace almost every organ in his body. This is not the case, however, with the brain and spinal cord as these structures will not regenerate. Nevertheless, with recent developments in neurophysiology and technology it is becoming possible to correct brain and spinal cord dysfunction. For example, a multiple electrode array has been implanted over the visual cortex of a blind patient to help overcome this sensory disability (Brindley and Lewin, 1968). Attempts have also been made to cure severe nerve deafness by implanting electrodes in the cochlea, auditory nerve and central auditory pathways, and stimulating the auditory system electrically (Djourno and Eyries, 1957; Doyle et al., 1964; Simmons et al., 1964; Simmons et al., 1965; Michelson, 1971).

ItemExperimental studies on the surgical treatment of perceptive deafness( 1973)For many years research workers have tried to produce hearing artificially in man by electrical stimulation of the auditory nerve and inner ear, but the results are still far from satisfactory. Consequently, we have considered it necessary to carry out a series of experimental studies on animals to help determine the limitations of electrical stimulation, and whether it could be used to convey sufficient information to make speech intelligible.

ItemThe surgical treatment of perceptive deafness: an experimental study( 1970)A neurophysiological study was undertaken to determine which methods of stimulating the auditory system electrically has the greatest chance of reproducing the effects of sound. The auditory nerve and internal ear of the cat were stimulated electrically at different frequencies, and the effects on cell firing responses in the superior olivary nucleus were compared with those obtained by stimulating the auditory system with sound of the same frequency.

ItemA neurophysiological assessment of the surgical treatment of perceptive deafness( 1970)The results of treating patients with middle ear disease are now good, but the situation is not as satisfactory with perceptive deafness, and this is one of the major problems facing otologists today.
