Normal and Pathological Adaptation of Compound Viii Nerve Responses in the Guinea Pig

Abstract

Adaptation of VIII nerve compound action potentials in response to trains of broad frequency spectrum clicks and high frequency filtered clicks is studied at various intensities in normal guinea pig under normal conditions, while masking with white noise and under pathological conditions after ototoxic antibiotic treatment. The results are discussed with respect to the clinical electro-cochleographic adaptation studies in man and the so-called two populations of receptors and nerve fibres in the cochlea.
