Between-participant variance in RSFC. (A)Top row: Between-participants variability (standard deviation across participants) in RSFC for each ROI pair. Colorbar represents the magnitude of between-participants variability. Bottom row: Regional between-participants variability in RSFC, obtained by averaging the standard deviation of RSFC across all ROI pairs for each ROI. Similar to adults, children exhibit the greatest relative degree of between-participants variability within control and attention networks. (B) First 10 principal components of RSFC across participants in the discovery and replication datasets, accounting for 11.88% and 11.73% of the total variance across participants, respectively. Similar to prior work in adult samples (Smith et al., 2015), reproducible motifs of between participant variance are observed outside of traditional network architecture.
