    The auditory cortex and auditory deprivation: experience with cochlear implants in the congenitally deaf [Abstract]
    Shepherd, R. K. ; Hartmann, R. ; Heid, S. ; Klinke, R. ; Blamey, P. J. ; Dowell, R. C. ; Clarke, Graeme M. ( 1995)
    The primary auditory cortex (AI) exhibits a topographic representation of the organ of Corti in normal hearing animals. Plasticity studies have shown that this orderly representation of frequency can be modified following a restricted hearing loss or by behavioural trainingl,2. Little is known, however, of the effects of a profound hearing loss on AI, although a number of early studies have suggested an enhancement of activity from other modalities3. Knowledge of the functional status of the central auditory pathway in the profoundly deaf, and the ability of these structures to undergo reorganization particularly following long periods of auditory deprivation - are important issues for the clinical management of cochlear implant patients. In this paper we review our recent clinical and experimental experience with cochlear implants in the congenitally deaf.
