List of significant clusters for group-level analyses on voxelwise low-frequency signal power

Region	L/R	Coordinates			Cluster size	p-FDR	T-score
		x	y	z
Effect of F1 on whole-brain fALFF
Middle frontal gyrus	R	32	22	58	350	< 0.001	− 5.92
Frontal pole	R	46	46	− 20	125	0.02	− 5.25
Frontal pole	R	30	58	− 4	124	0.02	− 4.70
Middle frontal gyrus	L	− 38	34	38	120	0.02	− 5.32
Superior frontal gyrus	L	− 24	26	54	101	0.04	− 5.28

Cluster threshold, p-FDR < 0.05; voxel threshold, p uncorrected < 0.001; p-FDR, FDR-corrected p value on cluster size; L/R, left or right hemisphere; fALFF, fractional amplitude of low-frequency fluctuation; N.B., no significant cluster was identified when investigating the effect of F2 on whole-brain fALFF
