Two different 4 × 1 anodal HD-tDCS interventions. The position of electrodes is based on the international 10–10 system. Indicated locations were used for stimulation (blue: cathode; red: anode). For “Group_1,” the target zone was located on the left dorsolateral prefrontal cortex, and the electrode montage was as follows: cathode placed on the Fp2 location and the other four anode electrodes placed at F1, F3, FC1, and FC3 locations. For “Group_2,” the target zone was in the dominant anterior temporal lobe, and the electrode montage was as follows: cathode positioned on the FP2 and the other four anode electrodes on F7, FT7, T9, and FT9. The Neuroelectrics Instrument Controller (NIC2) software was used to create this figure
