Non-invasive brain stimulation study of memory

This study was designed to better understand the role of electrical brain activity in the control of memory. The current study has no immediate benefit to the participant. However, the results of this study may be used to develop novel tools for the treatment of psychiatric mood-disorders that involve a detriment in cognitive control. The study requires approximately 15 hours of participation across five sessions. In the first session, you will do a computerized task and complete questionnaires about your mental health and personality. Based on your task performance, you may advance to the next stage of the experiment. In the next sessions, your brain activity will be recorded using electroencephalography (EEG), sensors on your scalp, and with magnetic resonance imaging (MRI). Finally, you will receive transcranial magnetic stimulation (TMS) during performance of a memory task.
