The purpose of this study is to test the safety, efficacy and mechanism of action of subgenual cingulate (Cg25) deep brain stimulation (DBS) for major depression in patients who have not responded to prior antidepressant treatments. Participation in the study will continue for ten years or until the device receives FDA approval for depression. Forty (40) patients will be enrolled in this study.
