Tinnitus and Hyperacusis (TH)
Instructional Level: Advanced
It is hypothesized that decreased central inhibition, related to reduced auditory stimulation in hearing loss, may underlie the pathophysiology of tinnitus. However, many individuals with clinically normal hearing report tinnitus. Thus, it is unclear whether inhibitory processes, independent of cochlear damage, contribute to the tinnitus percept for this population. In this presentation, recent findings on atypical inhibitory function in adults with mild tinnitus and normal hearing are discussed, including clinical applications of electrophysiological sensory gating as a measure of tinnitus.
