2. Assess the resting-state neural connectivity in patients with non-bothersome tinnitus. Findings from the comparison of functional connectivity magnetic resonance imaging (fcMRI) from subjects with bothersome tinnitus in our current rTMS clinical trial to normal age-matched controls without tinnitus demonstrates that subjects with bothersome tinnitus have dramatic alterations in cortical attention and control networks. Our hypothesis is that the fcMRI-defined changes in the attention and control networks reflect the impact of excessive auditory stimulation in patients with bothersome tinnitus and explains the difficulty with concentration, short-term memory, and other common problems. To fully test this hypothesis we need to obtain fcMRI of the attention network among subjects with tinnitus but without bother and compare the status of their neural networks with those of tinnitus subjects with bother and with normal controls.
