The purpose of this research is to understand how a neurostimulation technique, transcranial electrical stimulation (tES), affects brain function in adults with chronic subjective tinnitus measured with functional magnetic resonance imaging (fMRI). This study targets a specific kind of tES called transcranial direct current stimulation (tDCS), where a mild, constant current is passed between electrodes placed on the scalp.


This is an investigator-initiated MRI study of High Definition (HD) transcranial electrical stimulation (tES) in adults with chronic subjective tinnitus. HDtES is a mild, noninvasive form of brain stimulation using small electrodes to target a small part of the brain/cortex. Primary outcomes are changes in brain function and connectivity measured with MRI before and after a single 20-minute session of HDtES. Secondary outcomes are changes in tinnitus symptoms after 20-minutes of HDtES on 5 consecutive days.
