Handedness-Dependent Brain Networks Re-organization During Visuo-Motor Task Execution

The aim of the present study was to investigate handedness-dependent organization and functioning of brain networks during visuomotor integration processes. Specifically, a connectivity study was conducted on EEG traces acquired on a group of healthy volunteers during a resting (baseline) condition and the execution of a visuomotor task with the dominant and non-dominant hands. Our results showed that an enhanced network reorganization is observed in the mu band during the movement performed with the right hand with respect to the baseline condition. Conversely, more evident reorganization was observed for the movement performed with the non-dominant hand when dealing with the beta band. These results suggest that different brain functional reorganization strategies are used to accomplish motor tasks with the two body sides.
