Deep Brain Stimulation

for Neurological and Psychiatric Conditions

We propose to study approach/avoidance behavior as measured by the Approach Avoidance task in 20 epilepsy patients undergoing implementation of depth electrodes for seizure monitoring in the Epilepsy Monitoring Unit at MGH. We will also study the effects of VC/VS electrical stimulation on approach-avoidance conflict in 20 adult patients who have undergone DBS implantation for severe MDD and/or OCD. There are 100-200 patients in the world with DBS electrodes in the VC/VS, and our research team cares for more than any other institution. Both participant groups will be assessed with respect to reward-aversion decision conflict using the task. The task will be performed with concurrent EEG recordings in DBS patients, and with continuous recording through our invasive neurophysiology rig in EMU subjects.

Focused Ultrasound

for Bipolar Disorder

The specific aim of this proposed study is to investigate the feasibility and therapeutic potential of transcranial focused ultrasound (tFUS) as a treatment for bipolar disorder (BD). Specifically, the investigators will study the effects of amygdala tFUS on corticolimbic activation during an emotion regulation task in BD, the effects of amygdala tFUS on corticolimbic resting-state functional connectivity in BD, and explore the relationship between tFUS-associated changes in amygdala activity and mood symptoms. The investigators hypothesize that transcranial focused ultrasound (tFUS) of the amygdala will be associated with decreased amygdala activation and increased ventromedial prefrontal cortex activation during a modified version of the Multi-Source Interference Task (MSIT) paired with affective pictures from the International Affective Picture System (IAPS). The investigators also hypothesize that tFUS of the amygdala will be associated with increased resting-state functional connectivity between the amygdala and ventromedial prefrontal cortex. Finally, the investigators hypothesize that tFUS-associated reductions in amygdala activity could be positively correlated with reductions in depressive symptom scores and global improvement.
