Effect of Stimulation of Dorsolateral Prefrontal Cortex on Language Control

"We will use a non-invasive, reversible transcranial direct current stimulation (tDCS) using a low-intensity electrical current. We will use Anodal and Sham tDCS.~* Anodal: Active anodal electrode over F3 (EEG system) and return electrode over right supraorbital area. A 1.5mA current will flow between the electrodes for 20min. To decrease current-induced injuries, at the beginning, the current reaches from 0 to 1.5mA during 30 seconds (fade-in), and decreases from 1.5mA to 0 in 15 seconds at the end (fade-out).~* Sham: The parameters mimics the A-tDCS (i.e. electrode placement, fade-in and current intensity), except the duration of stimulation: the current will reach to 1.5mA in 30 seconds (fade-in) and lasts only for 30 seconds (to give the initial sensation of stimulation)."
