About this trial
This study will evaluate a new form of non-invasive brain stimulation for individuals with depression. Personalized low-intensity transcranial focused ultrasound stimulation will be delivered using a range of stimulation parameters during psychological and physiological monitoring. Individualized optimal targets will be selected using structural MRI and diffusion tractography. Brain target engagement will be evaluated using functional MRI.
