Tinnitus is the perceived sensation of sound without actual acoustic stimulation that affects 50 million Americans, with 15 million being significantly bothered. Using functional connectivity MRI (fcMRI), the investigators have found distinct differences in the cortical attention networks between patients with bothersome tinnitus and age-matched controls. These novel findings suggest that some of the classic and most disturbing characteristics of tinnitus result from derangements in cortical pathways. Using a validated task-based functional MRI (fMRI) paradigm developed at Washington University, the investigators will explore the ventral and dorsal frontoparietal cortical attention networks in patients with bothersome tinnitus and non-tinnitus controls.
