Fig. 4: Glass brain representation of mean redundancy of each group for each brain region/ROIs (upper row) and between-group differences (bottom row).

Glass brain representation of regional (ROIs level) redundancy a Healthy Control (HC), b PD with cognitive normal ability (PD-CN), c PD with severe hyposmia (PD-SH and d whole brain mean comparisons of HC, PD-CN and PD-SH, e group differences of HC > PD-CN and f group differences of HC > PD-SH. The between-group difference for ROI’s was computed using a two-sample t-test with Bonferroni corrections for multiple comparisons. Negative t (blue to sky color) represents PD-CN and PD-SH to have lower redundancy in respective brain regions than HC.
