Sham repetitive TMS (sham rTMS)
Cool-B65 A/P coil
To quickly switch between active and sham TMS trains, we used a novel dual coil approach (Fig. S13). The active TMS coil was positioned over the left dlPFC while the sham coil was positioned over the right dlPFC. The sham coil was a MagVenture Cool-B65 A/P coil with the sham side facing the scalp and fixed in place using a coil holder. Electrical current was delivered during sham TMS trains over the left frontalis muscle, using two surface electrodes (Ambu Neuroline 715) in order to approximate the somatosensory sensations arising from skin mechanoreceptors and scalp muscles during the active TMS condition
