Negative correlation between the UPDRS-III motor score and the general connectivity (eigenvector centrality) in PD patients (N = 24) regardless of medication condition. The better the motor state of patients, the more connected is the cerebellum with the other motor regions in the network restricted by mask defined on Fig. 1. The dot plot demonstrates this relationship in a maximum selected from the correlation map (p < 0.05, family-wise error-corrected at the cluster level). Each patient is represented by two dots (with the OFF and the ON condition)
