Abstract
The multi-channel cochlear implant is the first clinically successful interface between the world of sound and human consciousness, and the first means of giving severely deaf people hearing and speech understanding, and children spoken language. It has arisen from multi-disciplinary research in neurophysiology; communication, electronic, mechanical and bioengineering; neurobiology; anatomy and pathology; surgery; psychophysics; speech science; audiology and education. Physiological research showed that brainstem nerve cells could only respond to electrical stimuli up to 500pulses/, but they fired deterministically rather than stochastically which is the case with sound. Behavioural research..
