VEP changes in healthy subjects induced by excitatory (rTMS-QPE) or inhibitory (rTMS-QPI) quadripulse rTMS over the visual cortex. The last two columns indicate either no significant change (=), a significant increase (🡹), or decrease (🢃) (p < 0.05) between pre-rTMS recordings (T1) and recordings performed immediately after (T2) or 3 h after rTMS (T3).
