Figure 1.

(A and B) Illustration of the electrode positions for conventional montages (A) and alternative montages (B). For the conventional montages, two electrode sizes were tested: 35 cm² (not pictured) and 25 cm². The alternative montages used 9 cm² electrodes. Red electrodes refer to the anode, blue electrodes refer to the cathode. (C) Illustration of the region of interest (MNI coordinates: x = 40, y = − 76, z = − 46; 5 mm radius) used in the current study, plotted on coronal (top) and axial (bottom) views of a standard MNI brain.
