FIGURE 4

An illustration of electric field maps induced by (A) anodal tDCS (right M1), (B) cathodal tDCS (left M1), and (C) bihemispheric tDCS montages. Shown are group mean electric field maps for children (red) and adults (blue), in the range of 0.20–0.45 V/m, overlaid on three orientations (axial, coronal, sagittal) of an MNI template brain. (D) Example of electric fields induced by anodal tDCS of right primary cortex in a 6.5 (child, top) and 43.0-year-old (adult, bottom).
