Hearing loss; Efferent feedback to the cochlea; Auditory brainstem more


Amanda Lauer, Ph.D., focuses her research on the perceptual and central nervous system consequences of hearing loss. The overall goal of her research program is to investigate how hearing loss changes synaptic organization of brain pathways and how those changes are reflected in behavior and auditory processing. Understanding the interplay between the effects of peripheral auditory damage and higher order function is of particular importance given our increasing exposure to noisy environments and the increased prevalence of hearing disorders in our aging population. Recent studies have focused on animal models of tinnitus, hyperacusis and temporal processing abnormalities. more
