Ultrasound zaps brain to reveal hidden signals
NCT ID NCT05303428
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether low-intensity focused ultrasound can temporarily alter brain activity in 80 healthy adults. Participants receive MRI and CT scans, then ultrasound to the brain, followed by fMRI to measure changes in thinking and resting brain signals. The goal is to understand how noninvasive brain stimulation affects cognition, which may help future treatments for addiction, pain, and mental health.
