Fig. 3

The hierarchical clustering of Group 2. At each cluster, the top two numbers represent the estimated approximately unbiased p value (AU, left, red, %) and bootstrap probability value (BP, right, blue, %), and the cluster identification number is indicated below (gray). The right branches of cluster #131 (Group 3) and cluster #157 (Group 4) are expanded in Figs. 4 and 5, respectively. For compactness, the length of the branches does not represent distances. The term “basal nuclei” is replacing the traditional but anatomically inaccurate term “basal ganglia” [30]
