Development of Objective Electrophysiological Tests for Tinnitus Based on Long-Lasting After-Discharges in the Inferior Colliculus
[Technical Report, Annual Report]

Pagination or Media Count:
Tinnitus is the sensation of ringing in the ears in the absence of a corresponding, physical sound and is a symptom of apathological response of the auditory system. It is common in the aging population and in military veterans in particular. Mostoften, tinnitus is associated with hearing loss due to exposure to loud noise. There is no objective or diagnostic test for tinnitus,little understanding of its causes, and no curative treatment. This projects goal is to create an electrophysiological test fortinnitus. We have shown that there are measurable and detectable changes in the electrophysiological activity in the centralauditory system in response to a long-duration sound this is a long-lasting afterdischarge where neurons continue to fire 2-3minutes after the sound has stopped.
