This study will evaluate a new form of non-invasive brain stimulation for individuals with depression. Personalized low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychological and physiological monitoring. A well-tolerated stimulation protocol will then be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial to evaluate brain target engagement using magnetic resonance imaging.
