Resting motor thresholds.

	Left M1		Right M1
	RMT_pre (% MSO)	RMT_post (% MSO)	RMT_pre (% MSO)	RMT_post (% MSO)
tACS	41.56 ± 1.59	41.84 ± 1.53	38.74 ± 1.21	38.79 ± 1.30
Sham	40.89 ± 1.30	40.16 ± 1.38	38.58 ± 1.22	38.50 ± 1.45

Resting motor thresholds (RMT) of left and right M1 as assessed with single-pulse TMS before (RMT_pre) and after (RMT_post) 10 min of 20 Hz tACS (tACS) or sham stimulation (sham). Note, that baseline RMT within each M1 was not significantly different between sessions and there was no significant change in RMT in neither M1 due to stimulation. % MSO, % of maximum stimulator output. All values are depicted as mean ± standard error of the mean. Please see “RMT” Section for details.
