Zapping the brain really does seem to improve depression

Now we know – zapping the brain with electricity really does seem to improve some medical conditions, meaning it may be a useful tool for treating depression. Transcranial direct current stimulation (tDCS) involves using electrodes to send a weak current across the brain. Stimulating brain tissue like this has been linked to effects ranging from accelerated learning to improving the symptoms of depression and faster recovery from strokes.

AF Researchers Studying The Brain

The 711th Human Performance Wing recently signed a Cooperative Research and Development Agreement with Rio Grande Neurosciences of Albuquerque, N.M., to expand its work in the field of transcranial direct current stimulation to include new stimulation methods. Specifically, the project will expand the 711HPW’s work by focusing on the development and evaluation of pulsed electromagnetic field stimulation, new tDCS paradigms, and transcranial alternating current stimulation.

Transcranial direct current stimulation shows promise for depression therapy

Small amounts of electricity similar to the output of a common 9-volt battery could improve life for people living with major depression, the most common mood disorder. A new study at the University of Kansas will investigate the potential of transcranial direct current stimulation, or tDCS, whereby a safe, low current of electricity is applied to the brain by placing electrodes on a person's scalp. The painless technique may be a useful as a therapy for depression, especially in conjunction with antidepressant medications.

Self-Control Isn’t Just Controlling Impulses, but Also Changing Perspective

This theory was tested using transcranial magnetic stimulation to disrupt the function of the pTPJ in two separate studies on volunteer subjects from the University of Zurich. The disruption of this subregion of the brain would ultimately indicate if the subjects still held their capacity of self-control or if they became selfish and impulsive. The first study investigated 43 subjects who performed two tasks.
