Figure 1.

Head model geometry, depicting the surfaces of the scalp, skull, CSF, GM, and WM (A). The position of motor and pre-motor areas are shown in panels (B,C): HK (red), SMA (orange), PMd (brown), and PMv (blue). The positions and orientations of the TMS coil, the electrodes in the montage with two 35 cm² electrodes and the ones in the montage with the π cm² anode are shown in panels (D–F), respectively. The angles shown in panels (B,C) represent the azimuthal angle (φ) and the polar angle (θ), respectively.
