Given is the mean ± S.E.M, and, in italics, the p-values of an ANOVA on ranks. For pyramidal cells in (A): ADL, apical dendritic length [μm]; BDL, the average basal dendritic length per cell [μm]; the number of dendritic segments; for interneurons in (B): MDL, mean dendritic length [μm] per cell; MDS, mean dendritic segments; no. of PD, number of primary dendrites; n, number of neurons analyzed.
