Figure 3

Variations in electrode montages extracted from the 16 reviewed studies. (A) Shows the relative numbers of studies out of all 16 studies that chose frontal, temporal or temporo-parietal cortical targets for tDSC. (B) Depicts exact anode and cathode positions as well as the number of studies that applied respective montage. (C) Compares the frequency of anodal left, right, and bihemispheric cortical stimulation (the anode is usually considered as the active electrode).
