TABLE 2.

Descriptions of significantly different brain regions in the CBF-ReHo ratio among groups.

Brain regions (AAL)	Peak MNI coordinates (mm)			Peak F value	Cluster size (mm3)
	X	Y	Z

Right middle temporal gyrus	66	−30	−9	16.56	178
Left putamen	−24	24	−9	17.95	296

Left lingual gyrus	−12	−69	0	14.44	162

These clusters are referred to multiple comparisons correction using the FWE rate (a cluster-defining threshold of P = 0.001 and a corrected cluster significance of P < 0.05).

CBF, cerebral blood flow; ReHo, regional homogeneity; HC, healthy control; PD, Parkinson’s disease; NC, normal cognition; MCI, mild cognitive impairment; ANOVA, analysis of variance; AAL, automated anatomical labeling; MNI, Montreal Neurological Institute; FWE, familywise error.
