SimNIBS simulation of TMS setup. Demonstration of the spread of electrical field using SimNIBS 4 (“Earnie” head mash) when positioning the TMS coil over the right DLPFC (F4). Results are similar for the left DLPFC (F3) stimulation. SimNIBS did not allow us to simulate sequential bilateral stimulation. The electric field is represented as volts per meter (V/m).
