Neural correlates of electrically-induced cochlear dysfunction.

Prolonged low intensity galvanic currents produce scattered but sharply cicumscribed areas of destruction in the guinea pig cochlea. As well as providing opportunities for studying possible electrically-induced injuries during artificial auditory stimulation of the deaf, such preparations present an unusual opportunity to study the relations between patterns of compound auditory nerve action potentials and morphological changes, which could be useful in evaluating the various computer models of cochlear function at present being developed.
