Figure 2. Pattern of age-related rsFC change.

The top row shows the inference matrices of −log₁₀(p-values) indicating the significance of age-related effects on individual rsFC edges. Higher values (red colors) denote greater significance. The middle row displays the inference matrices of t-statistics that represents the effect size and direction of age-related effects on individual rsFC edges. Negative values (blue colors) indicate age-related declines; positive values (red colors) mean age-related increases. The third row demonstrates the distribution of the t-statistics of the effect of aging on all individual edges. The prevalence of age-related declines in rsFC shift both histograms to the left.
