RecruitingDevice studyUsing Electrophysiology to Index Non-invasive Brain Stimulation Effects on Reward System Functioning in DepressionDepression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.
