Bimanual movement skills require coupling of the two hands to coordinate their individual contributions towards a common goal. Since the two hands are controlled each by their contralateral hemisphere, coupling requires Information exchange (crosstalk) through the corpus callosum. If not processed appropriately, however, crosstalk can lead to involuntary movements (such as mirror movements) in the other hand. In this study, we showed that the relationship between brain (network connectivity) and behaviour (bimanual coupling) is task-dependent, but that predominantly left frontocentral networks are involved. These results can help us further our understanding on the mechanisms and impact of different neuromotor and cognitive disorders on bimanual coordination. Here you'll find the new paper
