CMM = congenital mirror movement; HVs = healthy volunteers; SMA = supplementary motor area. MNI coordinates were derived from a 2 × 2 ANOVA Group (CMM patients; HV) × Condition (unimanual right; bimanual). p < 0.05 corrected at the whole brain level. We then used pairwise t test to compare the activations between CMM patients and HV during the preparation of unimanual and bimanual movements.
