TABLE 2.

Differences of fALFF values between pED and HCs.

Brain regions	MNI coordinate			Cluster size	Peak t-value
	X	Y	Z
SFGmed.L	−9	42	27	26	−5.47
LING.L	−15	−42	−3	63	−6.60
PUT.L	−21	15	3	64	−6.38
PUT.R	21	15	6	17	−5.16

pED, psychological erectile dysfunction; HCs, healthy controls; fALFF, fractional amplitude of low-frequency fluctuation. X, Y, and Z: coordinates of peak voxels of the clusters in the montreal neurological institute (MNI) space. SFGmed.L, left medial superior frontal gyrus; LING.L, left lingual gyrus; PUT.L, left putamen; PUT.R, right putamen.
