Figure 2

Group differences in alpha-range connectivity between HR-ASD ( N = 10) and comparison groups (LR, N = 26; HR-no-ASD, N = 18). (A) Networks of increased connections in infants with ASD. NBS showed significantly higher functional connectivity in HR-ASD infants as compared to both LR and HR-no-ASD infants. The nodes (electrodes) and edges of the hyper-connected networks are loosely modeled on the standard brain image. (B) Overlap of the NBS clusters of the elevated connections revealed by HR-ASD vs. LR and HR-ASD vs. HR-no-ASD comparisons. (C) Difference between numbers of connections elevated (Mann-Whitney, P < 0.05, uncorrected) in the HR-ASD group and in comparison groups. Positive values correspond to a greater number of elevated connections in HR-ASD infants than in the comparison groups. Negative values correspond to a greater number of elevated connections in the comparison groups. Note clustering of over-connected sites over fronto-central regions.
