Study of Low-intensity Focused Ultrasound Effects on Cognitive fMRI Signals
Sponsor: Virginia Polytechnic Institute and State University
Summary
Study aims to examine the effects of noninvasive brain stimulation on brain signals. This insight may have potential clinical implications for addiction, pain, and mental health populations. Participants will receive MRI and CT imaging. Participants receive low-intensity focused ultrasound (LIFU) to temporarily change brain activity. Participants then receive fMRI scans to measure changes in both resting and cognitive brain signaling using structured tasks. Heart rate, blood pressure, respiratory rate, and skin moisture is monitored. Participants complete a battery of questionnaires, both behavioral and symptom monitoring. The study takes place over 4 study visits.
