Auditory Perceptual Impairment clinical trials at University of California Health

The present study will evaluate the effects of both aging and nicotine on psychophysical tasks and electrophysiological measures. Nicotine will be administered to study participants in the form of gum that is available as an over-the-counter medication. The hypothesis is that nicotine will reverse the detrimental effects of aging on auditory processing. The proposed experiments will characterize the effects of nicotine and may eventually lead to improved treatments of hearing loss in a variety of patient populations and in healthy aging.
