Brain activation during the delay period in healthy volunteers (HVs) and congenital mirror movement (CMM) patients. (a) Anatomical location of brain areas that are more activated during BIP (preparation of bimanual movement) compared to unimanual preparation (preparation of unimanual movement; positive effect of condition). (b) The interaction between age and group during motor preparation showed the sole involvement of the left supplementary motor area proper (upper panel). Whereas motor preparation‐related activation in this area increased with age in CMM patients whereas it was independent from age in HVs (bottom panel) [Color figure can be viewed at http://wileyonlinelibrary.com]
