Figure 2

Electric field for three cortical locations: The electric field distribution (V m−1), just within the cortex for three locations. On the top row the field strengths \( \left|\overrightarrow{\mathrm{E}}\right| \) for (A) the right motor cortex (MR), (B) the left premotor cortex (PML) and (C) the supplementary motor area 3 cm anterior to Cz (SM1) are displayed. In the bottom row the field strengths perpendicular to the CSF-GM boundary E are shown for (D) MR, (E) PML and (F) SM1. For the later scale, a positive value means directed inward and a negative means directed outward. The black dot indicates the location of the center of the TMS coil. The direction of the primary electric field directly under the coil center is indicated with the black arrow.
