At the first study visit, you will meet with a member of the study team and conduct interviews to understand your experience with depression. Then, we will record electrical brain activity while you complete a decision-making task. In the second session, you will receive new strategies to manage your depression, and you may or may not receive low-current electrical stimulation with it. In a third session two weeks later, you will complete the same task while electrical activity is recorded. Finally, you will be sent some questionnaires to complete online from home.
