Help researchers at Butler Hospital and Brown University understand how depression changes the brain! Our research team is looking for HEALTHY participants for a study on Major depressive disorder’s (MDD) Impacts on Mechanisms of Inhibitory Control (MIMIC study)! We’re currently recruiting people who are middle-aged (30-60 years old) and who have NO HISTORY OF DEPRESSION. During the one-time two-hour study appointment at Butler Hospital, you will complete surveys, perform computerized tasks, and have your brain waves recorded with an EEG cap that sits on top of your hair and scalp! Participants are compensated for participating and receive $50. To check eligibility or sign up, please email the study team
