From: Neurophysiological insights into catecholamine-dependent tDCS modulation of cognitive control
The EP induced by anodal tDCS with the described electrode configuration was computed using the “COMETS2” toolbox83. The anode (5 × 5 cm) was positioned above the rIFG, centered between electrodes FC4 and F8 (red patch in the right image). The reference electrode was positioned contralaterally between the neck and deltoid muscle. The input current was 2 mA, with colors denoting simulated electrical potential. Abbreviations: tDCS (transcranial direct current stimulation), rIFG (right inferior frontal gyrus), mA (milliampere).
