A Endogenous connectivity in patients and controls (DCM-A-matrix, P < 0.05, FDR-corrected). B Modulatory effects on effective connectivity in patients and controls during movements of the affected and unaffected hand (DCM-B-matrix, P < 0.05, FDR-corrected). C Synopsis: Differences between patients and controls.

Green arrows = positive coupling (facilitation); Red arrows = negative coupling (inhibition); Dashed arrows = significant weaker coupling in patients as compared to controls; White arrows = no significant differences between patients and controls.
