Dynamic reconfiguration of visuomotor-related functional connectivity networks

Abstract Cognitive functions arise from the coordination of large-scale brain networks. Yet, the principles governing interareal functional connectivity dynamics (FCD) remain elusive. Here, we test the hypothesis that human executive functions arise from the dynamic interplay of multiple networks. To do so, we investigated FCD mediating a key executing function, known as arbitrary visuomotor mapping, using brain connectivity analyses of high-gamma activity recorded using magnetoencephalography and intracranial electroencephalography. Visuomotor mapping was found to arise from the dynamic interplay of three partly-overlapping cortico-cortical and cortico-subcortical FC networks. First, visual and parietal regions coordinated with sensorimotor and premotor areas. Second, the dorsal fronto-parietal circuit together with the sensorimotor and associative fronto-striatal networks took the lead. Finally, cortico-cortical interhemispheric coordination among bilateral sensorimotor regions coupled with the left fronto-parietal network and visual areas.…
