Boosting Psychotherapy Effects by Means of Transcranial Direct Current Stimulation

TDCS is a noninvasive neurostimulation technique involving the transcranial application of a low-amperage electric current at a region of the cerebral cortex involved in the pathogenesis of major depression, the dorsolateral prefrontal cortex. In healthy subjects, the administration of excitatory tDCS on the left DLPFC improves the regulation of attention on information characterized by negative emotions, as does the administration of inhibitory tDCS on the DLPFC Right tDCS produces small changes in the neuronal membrane potential, thus increasing or decreasing the excitability of the stimulated tissue. Simultaneous administration to behavioral tasks designed to activate the stimulated cortical region should achieve a synergistic, amplifying the plasticity stimulated by the task.
