Comparison Between Transcranial Stimulation Protocols With Continuous Current in the Chronic Migraine

Transcranial Current Stimulation equipment consists of an ammeter (measured with current intensity), a potentiometer (voltage controller between the electrodes), a generator (two 9-volt batteries) and two electrodes (anode and cathode). The direct low-amplitude currents released by the electrodes reach the cortex and modify the neuronal potentials.
