Cortical Effects of Aging and Hearing Loss



Aging and hearing loss have profound consequences for the function of auditory cortex (AC). We first discuss the effects of aging on auditory processing followed by surveying consequences of deafness in the AC. In the aging effects, we begin with an overview of the changes that occur in older humans, followed by considering animal models of aging and cortical function. Next, we discuss possible neural mechanisms underlying aging effects and potential interventions that may retard or even reverse some of these age-related changes.
