A depiction of electrode positioning in a 10–20 EEG system. The anode (red, 5x5 cm) over the left dorsolateral prefrontal cortex (F3) and the cathode (blue, 6x8,5 cm) over the right orbitofrontal region (Fp2). It was ensured there is at least 8 cm between these electrodes in order to prevent shunting.
