Intrinsic timescale maps were compared directly between the two datasets (scatter plot). Each brain region (i.e., each circle in the scatter plot) is colored based on the region’s rank along an organizational axis of the cortex that spans sensorimotor to association cortices (S–A axis). (b) Intrinsic timescale in youth (HCPD and HBN dataset) reflects the hierarchical organization captured by the S–A axis, such that sensorimotor regions have shorter timescales while association regions have longer timescales. Significance of the associations between cortical maps (i.e., scatter plots) was assessed using spatial autocorrelation-preserving permutation tests (i.e., spin test). rs denotes Spearman’s rank correlation coefficient. Linear regression lines are added for visualization purposes only. Asterisks in the boxplot denote significant differences in the means (two-tailed t test).
