Global and regional neurovascular coupling among groups. The mean CBF-ReHo coupling at the global level among groups (A) and representative scatter plots of the spatial correlations across voxels in individuals (B–D); regional neurovascular coupling of CBF-ReHo (E) and the significantly different brain regions in the PD-MCI group as compared with HC and PD-NC groups (F). *Indicates significant intergroup difference to HC group; ^#indicates significant intergroup difference to PD-NC group. CBF, cerebral blood flow; ReHo, regional homogeneity; HC, healthy control; PD, Parkinson’s disease; NC, normal cognition; MCI, mild cognitive impairment; R, right; L, left; MFG, middle frontal gyrus; MCC, middle cingulate cortex; MOG, middle occipital gyrus; IPG, inferior parietal gyrus; SMG, supramarginal gyrus; AG, angular gyrus.
