Top and bottom rows depict data from children and adults, respectively. Left and right columns depict unscrubbed and scrubbed data, respectively. Each panel shows the sub-network (community) organization within the appropriate dataset of a network composed of the 264 ROIs studied in this report. Colors indicate sub-networks, and are independent in each panel, though congruent colors have been chosen across panels for ease of visual comparison. Only right hemispheres are shown, but results are generally symmetric across hemispheres. The numbers between panels indicate the normalized mutual information of community assignments between panels, a standard measure of how similar two sets of community assignments are (values of 1 indicate identical assignments). Scrubbing adult data produced little change in community assignments (NMI = 0.94), whereas scrubbing child data produced substantial changes in community assignments (NMI = 0.69). Moreover, though network organization in children and adults was initially quite dissimilar (NMI = 0.56), it became more similar with scrubbing (NMI = 0.70). This increase in similarity is not observed with random scrubbing (NMI = 0.58 ± 0.01 over 10 repetitions of random scrubbing in children and adults). The reorganization of functional network in children can be seen in the large contiguous patches of color (e.g. orange) in unscrubbed data, which become parts of distributed communities in scrubbed data (see red circles for an example). All graphs are thresholded at 10% edge density (r > 0.16, 0.15, 0.15, and 0.15 clockwise from upper left). For ease of visualization, nodes in communities with fewer than 4 members are colored white, and thus white nodes are explicitly not a single community.
