FIGURE 3.

The networks showing altered morphological connections compared among the PD‐M, PD‐N and HC groups. Every node denotes a brain region and every line denotes a connection, mapped onto the cortical surfaces using BrainNet viewer software (www.nitrc.org/projects/bnv/). Red (blue) color represents increased (decreased) morphological connections. Abbreviations: PD, Parkinson's disease; PD‐M, PD with mild cognitive impairment; PD‐N, PD with normal cognition; HC, healthy control; AMYG, amygdala; CRBL, cerebellum; DCG, median cingulate and paracingulate gyri; HES, Heschl gyrus; IOG, inferior occipital gyrus; OLF, olfactory cortex; PCG, posterior cingulate gyrus; PCUN, precuneus; PHG, parahippocampal gyrus; PoCG, postcentral gyrus; PUT, putamen; REC, rectus gyrus; SMA, supplementary motor area; SPG, superior parietal gyrus; STG, superior temporal gyrus; TPOmid, temporal pole: middle temporal gyrus
