Two distinct projects to launch in the Fall 2012:
- Characterizing the long-term changes to the auditory brain (via extracellular neural recordings) and auditory perception (via acoustic startle reflex paradigms) of rats after persistent exposure to non-traumatic, moderate-level noise. This research may have important implications for hearing risks to humans working and/or living in moderately noisy environments at exposure levels that are presently considered acceptable by international standards. Funding from the National Institutes of Health (NIH) is pending.
- Characterizing the qualities of tinnitus in human subjects, and correlating these qualities with performance on a number of auditory perceptual tasks. This research may have important implications for current theories of the neurophysiologic underpinnings of tinnitus. Funding from the American Tinnitus Association (ATA) is pending.
