Brain implants cure depression

Severely depressed patients who do not respond to conventional therapy may be helped by deep brain stimulation (DBS), according to the most-extensive study to date of the experimental procedure.

In a clinical trial in Toronto, Canada, 12 out of 20 patients who had stimulating electrodes placed in a brain area called the subcallosal cingulated gyrus showed significant improvement in their depression, with seven of them going into full remission.

You can compare this to a similar treatment for Parkinson's disease where an area of the subthalamic nucleus is stimulated by electrode. Look out drugs, direct neural stimulation is the wave of the future.
