Table 4.

Regions showing significant difference in FC analysis between Group C and Group I at 7 days after surgery.

Cluster name	Brain region	Cluster size	MNI coordinates			Effect size	t-value
			x	y	z
Cluster 1	Left orbital inferior frontal gyrus	144	−45	21	−3	0.99	8.64
	Left middle frontal gyrus	112	−45	45	1	0.89	3.66
	Left superior temporal gyrus	43	−45	−6	−6	0.43	3.38
	Left precentral gyrus	12	−48	6	21	0.31	2.60

The results were considered significant at voxel p < 0.05 (two-tailed, GRF-corrected). A positive t-value represented an increase in FC when compared Group I to group C.

FC, functional connectivity; GRF, gaussian random field.
