Transcranial Direct Current Stimulation

Transcranial Direct Current Stimulation (tDCS) involves the application of weak direct electric current to the head in a noninvasive and painless manner. tDCS with a constant current intensity of 2 milliamps (mA) will be applied for 20 minutes per session daily for 2 weeks (Monday to Friday) via the Soterix 1x1 tDCS mini-CT Stimulator device. Participants will self-administer tDCS at their home or a private room for two weeks (Mondays-Fridays) under real-time supervision by the research staff.
