Fig. 4.
Modulatory effects on effective connectivity (main effect “hand”) during right and left hand fist closures (DCM B-matrix; n = 2 × 18; P < 0.05, FDR-corrected). Green arrows = positive coupling rate, red arrows = negative coupling rates. The width of each arrow corresponds to the coupling strength. For mean coupling parameters and P-values (one-sample t-test against zero) see Supplemental Tables IIIa and IIIb.
