Fig. 2: Spatial patterns of brain states matrices (top row), their corresponding glass brain (middle row) and temporal differences between groups (bottom row).

a Brain States (patterns) for six different states matrix and b their spatial distribution in the glass brain plot using BrainNet viewer. The brain state matrices are computed by taking all the healthy controls (HC), Parkinson’s with cognitive normal ability (PD-CN) and Parkinson’s with severe hyposmia (PD-SH) dynamic connectivity matrices data. To characterize the different groups, we assess c brain state rate of occurrences (probability) for HC, PD-CN & PD-SH. In the bar graph (c) star represents between-group significant difference P < 0.05 Bonferroni-uncorrected, and every dot represents the individual subject’s mean brain state rate of occurrences values for their corresponding groups.
