Local minimum coil housing curvature mapped onto the surface of an MNI space head model (see Methods section of article for detailed description). For regions of the head, where its curvature is strong (i.e., in frontal areas and on the parietal bone), low values (blue) of coil curvature around 20‐ to 25‐cm in diameter could be used. For accessing the flatter areas of the head (e.g., somatosensory and motor areas), a flatter coil housing also is needed (30–40 cm; green/yellow areas). A curvature of 45 cm was needed for the coil housing used in this study, which makes most parts of the brain accessible to TMS stimulation with the MR coil array in place.
