Morphological homeostasis in individual subtrees. (A) Schematization of the partition of the degree p of a bifurcating branch into the two daughters l and r and the four granddaughters a, b, c, and d. (B) Excess partition asymmetry for all data sets (1, Amaral CA3; 2, Amaral CA1; 3, Barrionuevo CA3; 4, Gulyás CA1; 5, Wearne Local Young; 6, Wearne Local Old; 7, Wearne Long Young; 8, Wearne Long Old; 9, Claiborne DG; 10, Turner CA1 Vivo; 11, Turner CA1 Aged; 12, Turner CA1 Vitro; 13, Turner CA3; 14, Turner DG). Averages (gray bars) and standard errors (white tops) were calculated over all bifurcations with two nonterminal daughters in all cells within each class. The numbers of such bifurcations and the P value assessing positivity of the mean are indicated over each bar. (C and D) A representation of the same analysis performed using length asymmetry and area asymmetry instead of partition asymmetry, respectively.
