ICC of EEG alpha asymmetry for all electrode pairs (F3/F4, F7/F8, P3/P4, P7/P8) for EEG system 1 (Brain Products) and EEG system 2 (BioSemi) for the eyes-closed (EC) and eyes-open (EO) condition, respectively

	System 1		System 2
	EC	EO	EC	EO
F3/F4	0.68 (0.63–0.73)	0.65 (0.60–0.70)	0.56 (0.50–0.62)	0.60 (0.55–0.65)
F7/F8	0.73 (0.69–0.77)	0.76 (0.72–0.79)	0.79 (0.76–0.82)	0.86 (0.83–0.88)
P3/P4	0.83 (0.81–0.86)	0.72 (0.68–0.76)	0.82 (0.79–0.85)	0.72 (0.68–0.76)
P7/P8	0.87 (0.85–0.89)	0.75 (0.71–0.78)	0.88 (0.86–0.90)	0.75 (0.71–0.79)

The brackets contain the 95% confidence interval of ICC. All ICC showed p values of p < 0.001
