Cochlear Synaptopathy and Neurodegeneration after Noise

Abstract

The focus of this proposal is on mechanisms and manifestations of noise-induced cochlear synaptopathy and the neurodegeneration that inevitably follows. Studies use pharmacologic and genetic approaches to probe the acute synaptic response and detailed physiologic and histologic assessment of acute and chronic consequences of the injury. Results will inform diagnosis and treatment of noise-induced injury, an issue of critical health importance to Navy personnel. Our recent work points to inner hair cell – afferent fiber synapses as the most vulnerable elements in the cochlea.
