Helen Mayberg wants guinea pigs
If you are within reach of Atlanta, Georgia, and are depressed (but not suicidal) and would like to have electrodes implanted in your brain then you could volunteer to be an experimental subject for Helen Mayberg and colleagues at Emory University.
“The purpose of the proposed study is to evaluate the safety, feasibility and efficacy of chronic, high frequency stimulation of the subgenual cingulate white matter (Cg25WM) using the ANS Totally Implantable Deep Brain Stimulation System as an adjunctive treatment for severe treatment-refractory Major Depression in twenty TRD patients, and to investigate potential mechanisms of action of this intervention.”
