Effects of 333 Hz tACS in representative subjects. The amplitude of MEPs evoked by biphasic TMS pulses delivered during voluntary muscular contraction through a standard figure-of-eight coil at the intensity of 100% AMT (AMT-biph – upper line) and by monophasic TMS pulses delivered through a figure-of-eight coil with the handle AP-oriented (AMT-mono AP – middle line) increased during 333 Hz tACS (T1). In contrast, the amplitude of MEPs evoked by monophasic TMS pulses delivered during voluntary muscular contraction through a circular coil at the intensity of 100% AMT (AMT-circ – lower line) increased both during and 5 minutes after 333 Hz tACS over M1 (T2).
