FIGURE 4.

Group differences in metabolic connectivity of DMN ROIs between healthy controls and cognitively impaired (PD‐MCI) or unimpaired (PD‐NC) PD patients. Color scale indicates the difference in correlation coefficients between the groups. Correlation coefficients were compared by Fisher's z test; *significant at p < .05. AGl, angular gyrus left; AGr, angular gyrus right; mPFC, medial prefrontal cortex; ParaHL, parahippocampal cortex left; ParaHR, parahippocampal cortex right; PC, precuneus cortex; PCC, posterior cingulate cortex; PD‐MCI, PD patients with mild cognitive impairment; PD‐NC, PD patients with normal cognition; pSMGl, posterior supramarginal gyrus left; pSMGls, posterior supramarginal gyrus left superior; pSMGrs, posterior supramarginal gyrus right superior; SFGl, superior frontal gyrus left; SFG mid, superior frontal gyrus mid; SFGr, superior frontal gyrus right; sLOCl, superior lateral occipital cortex left; sLOCr, superior lateral occipital cortex right
