Representation of a magnetoencephalography-based functional brain graph with 78 brain regions (network nodes indicated by numbers). Connections (lines between nodes) are the thresholded functional connectivity values (phase lag index) between node pairs. (A) Transversal view, frontal up. (B) Sagittal view, frontal left. Colors indicate clusters of brain regions that have a higher connectivity within the cluster than outside the cluster (modules). A predominance of midline transversal connections can be seen.
