3. Compare the resting cortical networks in subjects with non-bothersome tinnitus to subjects with bothersome tinnitus and subjects without tinnitus Our null hypothesis is that there are no differences in the resting-state cortical networks, especially the attention and control networks, between tinnitus patients who do not experience bother, tinnitus patients who do experience bother, and subjects without tinnitus. Through fcMRI, we will examine correlations in blood oxygen level dependent (BOLD) signals in established auditory, attention, control, and other brain regions in the resting brain and compare these findings to already collected fcMRI scans of bothered tinnitus patients, and controls (patients without tinnitus).
