Results of functional connectivity of cerebellar motor networks. (A) Increased functional connectivity between the cerebellar lobule VI and both the lower limb representation of M1 and the SMA in patients with orthostatic tremor (OT) compared to healthy volunteers (HV) displayed on the SPM canonical brain (top) and represented graphically (bottom). (B) Multiple regression results showing that functional connectivity between the cerebellum VI and the SMA correlated with tremor characteristics on the SPM canonical brain (top) and represented graphically (bottom). All group differences and multiple regression results are significant at P < 0.05 corrected at the level of the cluster. Clusters are superimposed on the SPM canonical brain. Plots display the dispersion of data points extracted from the global maximum (see Table 3 for statistical details).
