Modulating Escape Using Focused Ultrasound

This is a study to find out if a cutting-edge technology called transcranial focused ultrasound (tFUS) can be used to treat how people with anxiety or related concerns cope with emotional situations. tFUS is a brain stimulation technology that causes temporary changes in the activity of deep brain areas without a need for any surgery or other permanent or invasive procedures. This study is recruiting participants who recently started treatment for anxiety or a related concern to come in for 3 visits at the Medical University of South Carolina. At the first visit, participants will do interviews and surveys asking about anxiety and related concerns, and they do tasks where they respond to emotional pictures while brain activity is measured using magnetic resonance imaging (MRI). At the next two visits, participants again do a task where they see and react to emotional images, and this time the task is done once before and again once after receiving tFUS that either actively causes temporary changes (lasting for about an hour) in a targeted brain area or is not active (no changes elicited). At each tFUS visit, responses are measured with sensors worn on the hand, arms, face, and head (these visits do not involve MRI). Each visit in this study is expected to last between 2 - 3 hours. This study is not a treatment study, but it could help improve treatment in the future. Participants in this study are paid for their time.
