The overall goal of the Auditory Brainstem Library is to understand how abnormal auditory input... from the ear affects the brainstem, and how the brain in turn affects activity in the ear through efferent feedback loops. Our emphasis is on understanding the effects of different forms of acquired hearing loss (genetic, conductive, noise-induced, age-related, traumatic brain injury-related) and environmental noise. We are particularly interested in plastic changes in the brain that compensate for some aspects of altered auditory input, and how those changes relate to central auditory processing deficits, tinnitus, and hyperacusis. Understanding these changes will help refine therapeutic strategies and identify new targets for treatment. We collaborate with other labs in the Depts. of Otolaryngology, Neuroscience, Neuropathology, the Wilmer Eye Institute, and the Applied Physics Laboratory at Johns Hopkins, in addition to labs outside the university to increase the impact and clinical relevance of our research. view moreResearch Areas: hearing disorders, compound action potentials, auditory brainstem response, otoacoustic emissions, operation conditions, audiology, acoustic startle modification, hearing, neurology
