Figure 1.

ECT Electrode Positions and Estimated Electric Fields (E Fields). Right unilateral (RUL), bitemporal (BT), and bifrontal (BF) electrode positions are displayed in relation to the skin surface and pial surface of an MNI-space template head in top row (green circles marked estimated 10–10 EEG positions). On pial surfaces in top row, and gray-matter images in bottom row, color indicate the magnitude of E field estimated for each electrode position using SimNIBS software (https://simnibs.github.io/simnibs; warm colors indicate higher magnitude). Note that left electrode is not visible for BT electrode position in panel displaying skin surface.
