Summary

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.

Detailed description

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.

Conditions

• Tinnitus, Subjective

Interventions

Type	Name	Description
DEVICE	Transcranial Direct Current Stimulation	Transcranial Direct Current Stimulation (tDCS) uses a mild electrical current to make small (or subtle) changes to how the brain works (or functions).
