A Controlled Clinical Trial of Cathodal Transcranial Direct Current Stimulation in Patients With Refractory Epilepsy

Transcranial direct current stimulation (tDCS) is a safe, non-invasive method that modulates cortical excitability. In direct current polarization, the cerebral cortex is stimulated through a weak constant electric current in a noninvasive and painless manner. This weak current induces focal changes of cortical excitability increase or decrease depending on the electrode polarity- that last beyond the period of stimulation.

The same procedures just that in this case the machine produces only a 60 second stimulus at the beginning so the patient can feel the initial electric stimulus.
