Transcranial Direct Current Stimulation for Depression

Transcranial direct current stimulation (tDCS) is a method for noninvasive brain stimulation, where a weak electrical current is delivered through two scalp electrodes by a portable battery-powered stimulator.

For sham tDCS, the electrode positions and stimulation parameters will be the same as that used for anodal stimulation except that the current will be delivered only for the initial 30 seconds.
