Fig. 4: Correlations of post-central cortex FC with pPDU.

Scatterplots for PD (red) and ET (blue) patients of the mean FC of the cluster (highlighted in the inserts on the right, the most affected side is at reader’s left) showing a significant correlation of the caudate FC (y axis) with pPDU (x axis) in PD patients. FC of the caudate on the MAS with the homolateral superior parietal cortex shows an inverse correlation with pPDU in PD patients, with no significant correlation in ET patients in the same regions.
