A Dynamic state definition scheme. The strength of dynamic patterns at each time point from an example individual is presented. The temporal magnitude (y-axis) reflects the strength of the dynamic propagation pattern over time. At each time point, the pattern with the highest magnitude is assigned as the dominant state. B Age distribution of participants across developmental stages (children: 8–12 years, adolescents: 13–17 years, and early adulthood: 18–21 years) in the HCP-D cohort. C The proportion of time spent (occurrence ratio; bars indicate mean ± 95% CI across participants) is plotted for different developmental stages: children (N = 139), adolescents (N = 172), early adulthood (N = 97) in HCP-D, and middle-aged adulthood reference (HCP-A; N = 399). Statistical analyses include a one-way ANOVA across the four age groups to assess overall developmental effects, followed by pairwise two-sided t-tests between consecutive age stages to examine specific transitions with false-discovery-rate (FDR) correction. Statistical significance is denoted by asterisks (*: pFDR < 0.05). We additionally validated the observed differences in state occurrence ratios using the HCP Young Adult cohort (N = 892) as the adult reference (Figure. S3).
