Research Summary:

Deep brain stimulation (DBS) has been recently approved by the US Food and Drug Administration as a treatment for otherwise intractable patient diagnosed with obsessive compulsive disorder (OCD). One of the target used in clinic is the ventral striatum, encompassing at least but not only, the nucleus accumbens (NAc). The NAc has also been reported to be a efficient target for other psychiatric syndromes, such as depression. The possible mechanism of action this successful therapy has been hinted but fully understood. Our research aim clarify the network effect of NAc DBS using electrophysiology, pharmacology and behavior (combined or separately).
