Hierarchical clustering of Hyper-Variable genes by age in (A) cerebellum tissue, and (B) frontal cortex tissue. The vertical axis represents the age-regulated Hyper-Variable genes while the samples were clustered by age and plotted on the horizontal axis. The top heatmaps represent the positively correlated age-regulated genes while the bottom heatmaps represent the negatively correlated age-regulated genes. The age clusters decrease in age from left to right in both heatmaps and correspond to the following age ranges: \( {\overline{\mathrm{x}}}_1=79\ \left[58,98\right] \), \( {\overline{\mathrm{x}}}_2=45\ \left[32,57\right] \), and \( {\overline{\mathrm{x}}}_3=17\ \left[1,31\right] \)
