Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Low Intensity Focused Ultrasound
Device: Low Intensity Focused Ultrasound Device Low Intensity Focused Ultrasound Pulsation (LIFUP) of amygdala (a key area for anxiety) will be performed during two sessions. The proposed experiment will involve behavioral (e.g. HAM-A) and paramedical (i.e., MRI/fMRI) measurements just before and after each of the two LIFUP sessions (i.e., 5 non-consecutive minutes of stimulation in each session). The device does not produce a sound when operating and as such, the active group will well blinded. |
8 LIFUP Treatments
Other Names:

Sham Comparator: Sham
Sham Treatment consists of placing the device but not turning it on.
The device does not produce a sound when operating and as such, the sham group will well blinded.
