Modulating Escape Using Focused Ultrasound

Active non-invasive low-intensity focused ultrasound will be delivered using a proprietary head-worn device and control software from Attune Neurosciences. On an active stimulation day, focused ultrasound will be delivered to the brain region of interest using parameters from published research that are demonstrated to safely cause temporary changes in the activity in that brain area.

Non-active low-intensity ultrasound will also be conducted using a proprietary head-worn device and control software from Attune Neurosciences. On the sham stimulation day, the device will be activated in a manner that produces similar sensory effects (i.e., low-volume beeping-type noise from the device) but also prevents delivery of a focused ultrasound beam to the brain area of interest or any other brain area.
