TMS Conditions

	TMS Mode	TMS Regime	TMS Pulses	Train Duration	Frequency	IPI	Coil Handle Relative to Target Gyrus	Coil Surface Relative to Scalp
α-TMS	active	rhythmic	n = 5	4 × IAF cycle	IAF	fixed to 1000/IAF	perpendicular	tangential
α-TMS90°	active	rhythmic	n = 5	4 × IAF cycle	IAF	fixed to 1000/IAF	parallel	tangential
ar-TMS	active	arrhythmic	n = 5	4 × IAF cycle	NA	jittered by 0.7 × IPI, 0.8 × IPI, 1.2 × IPI, 1.3 × IPI	perpendicular	tangential
α-TMSsham	inactive	rhythmic	n = 5	4 × IAF cycle	IAF	fixed to 1000/IAF	NA	radial

The following abbreviations are used: IPI, interpulse interval; IAF, individual α-frequency; NA, not applicable. Note: in the formula for calculating individual jitter in ar-TMS, IPI refers to individual IPIs of the rhythmic regimes (= 1000/IAF). The presentation order of the four resulting, variable IPIs was randomized within each trial.
