The Tinnitus Research Unit is dedicated to understanding and ultimately treating the clinical problem of tinnitus, a condition often called “ringing in the ears” and formally defined as the perception of sound in the absence of any physical stimulus. While generally viewed as an “ear problem,” there is good evidence that tinnitus involves abnormalities of the brain and that the somatosensory, limbic, and auditory systems are all key players.
(1) using brain imaging (fMRI, MEG, evoked potentials) to test several hypotheses regarding the neural basis of tinnitus, including its association with hyperactivity in the CNS,
(2) examining the function of the auditory periphery to detect subtle, but potentially crucial, tinnitus-related abnormalities, and
(3) comparing imaging and other measurements with clinic outcome to identify physiologically-distinct tinnitus subtypes responsive to different treatments.
