Investigation of the Duration of Low-intensity Focused Ultrasound
February 19, 2024 updated by: Wynn Legon, Virginia Polytechnic Institute and State University
This project examines the effects of various durations of noninvasive neuromodulation on muscle contractions.
The investigators believe this study will help to better understand noninvasive brain stimulation techniques that may have the potential to aid in addiction, pain, and mental health issues.
Participants undergo structural imaging, a functional Magnetic Resonance Image (fMRI) and computed tomography (CT).
These images are used to align the low-intensity focused ultrasound (LIFU) and transcranial magnetic stimulation (TMS) devices to temporarily change brain activity.
Electromyography (EMG) will be used to record muscle contractions of the hand.
