The goal of this clinical trial is to learn how people respond to fear-related experiences in a virtual reality (VR) environment. The study will also look at how brain activity and body responses are connected to learning and memory of fear. To do so, we recruit individuals who are already implanted with a Responsive Neurostimulator (RNS) device for the treatment of epilepsy. This research may help improve our understanding of anxiety disorders and how to better treat them in the future. The main questions it aims to answer are: 1) How do people learn to associate certain cues in VR with feelings of fear or safety? 2) What brain and body responses happen during fear learning? Participants will: 1) Wear a virtual reality headset and experience different environments and sounds, 2) Have their brain activity, heart rate, and sweating measured, and 3) Receive safe, mild electrical pulses through the RNS device during the study to help study fear learning. Participants will attend one or more study sessions, each lasting about 3-4 hours.

Current clinical assessment tools are often not sensitive enough to detect and treat some subtle (yet troubling) problems after mTBI. In this study, the investigators will use wearable sensors to both assess and treat people with mTBI. Specifically, the investigators will provide immediate feedback, with visual and/or auditory, on movement quality during physical therapy. This immediate feedback on performance may improve outcomes as the investigators will measure multiple body segments including head movements simultaneously with balance and walking exercises. Such complex movements are needed for safe return to high level activity and military duty. The investigators will test this approach against a standard vestibular rehabilitation program. There are few potential risks to this study such as increasing symptoms and a small fall risk. Benefits include physical therapy for balance problems regardless of therapy with or without biofeedback. An indirect benefit is to have data on correct dosage of physical therapy. The investigators will also distinguish which concussion subtype profiles benefit most from physical therapy. This will help healthcare providers and patients by providing more information to help establish clinical guidelines and new tools for physical therapy.
