Molecular basis and clinical perspectives of deep brain stimulation for major depressive disorder.

It is possible to consider the stimulation of the cingulate gyrus in its portion below the corpus callosum (SCC, or subcallosal cingulate cortex) as an effective, promising, and safe alternative intervention for treatment-resistant depression. In studies with deep brain stimulation - DBS, when follow-on with functional magnetic resonance imaging and/or PET-CT (Positron emission tomography-computed tomography) is performed, it is observed an increase in the blood supply and glucose metabolism in this region, which is the anterior part of the limbic system. This same location has good experimental results also for the treatment of anorexia nervosa.
