Fig. 4.

Electric field simulation results for cortical lesion models (P1, P2, and P4). A) The normalized mean electric field strength in GM at each coil position for both left and right hemispheres (left and right columns, respectively). The black arrows above the columns indicate the coil orientation. The minimums are individualized for each participant (P1 |E|_min = 0.7499, P2 |E|_min = 0.7419, P4 |E|_min = 0.8788). For TMS coil positions directly above large cortical lesions the electric field strength is reduced. B) Raincloud plots (Allen et al., 2019) of the mean electric field strength over all stimulation locations. Orange dots indicate positions directly over the lesion (and equivalent positions over the non-lesioned hemisphere); green dots indicate positions over non-lesioned cortex. The spread of electric field strength over the lesioned hemisphere is larger than for the non-lesioned hemisphere.
