Values are mean ± SEM. Statistically significant differences (p < 0.05) were assessed by performing a nonparametric Kruskal-Wallis test followed by a post hoc Dunn-Holland-Wolfe test for pairwise comparison. Statistically significant differences were found for the following: Resting Vm: L2 versus L4, L2 versus L5A, L2 versus L5B, L2 versus L6, L3 versus L4, L3 versus L5A, L3 versus L5B, L3 versus L6, L4 versus L5A, L4 versus L5B, L5A versus L6, and L5B versus L6. Rin: L2 versus L4, L2 versus L5A, L2 versus L5B, L2 versus L6, L3 versus L4, L3 versus L5A, L3 versus L5B, L3 versus L6, L4 versus L5A, L4 versus L5B, L5A versus L5B, L5A versus L6, and L5B versus L6. Tau: L2 versus L4, L2 versus L5A, L2 versus L5B, L3 versus L4, L3 versus L5A, L3 versus L5B, L4 versus L5B, L4 versus L6, L5A versus L5B, L5A versus L6, and L5B versus L6. AP threshold: L2 versus L4, L2 versus L5B, L2 versus L6, L3 versus L4, L3 versus L5B, L3 versus L6, L4 versus L5A, L4 versus L5B, L4 versus L6, L5A versus L5B, and L5A versus L6. AP amplitude: L2 versus L5A, L2 versus L6, L3 versus L4, L3 versus L5A, L3 versus L6, L4 versus L5B, L5A versus L5B, and L5B versus L6. Rheobase: L2 versus L4, L2 versus L5A, L2 versus L5B, L2 versus L6, L3 versus L4, L3 versus L5A, L3 versus L5B, L3 versus L6, L4 versus L5A, L4 versus L5B, L4 versus L6, L5A versus L5B, and L5B versus L6.
