Graphs showing A) soma volume, B) the number of primary basal dendrites C) diameter distribution as a function of the distance from soma for the main apical dendrites (apical M), D) apical collateral dendrites (apical C), E) basal dendrites, and f) axon from human BA17, BA20, BA21 cortical areas, and human CA1 (HCA1) and mouse CA1 regions (MCA1). Measurements are reported as mean ± SEM. Additional graphs showing cell body cross-sectional area and surface area are shown in Supplementary Fig. 6A and B. The statistical significance of the differences is shown in Supplementary Tables 6 and 7.
