Largest somatic diameter and dendritic span in the vertical and horizontal plane are given. Apical dendrite (AD) and basal dendrites (BD, as all non-apical dendrites) were distinguished. In spiny stellates an AD is not available (n.a.). All values are µm unless otherwise indicated.

cComparison between star pyramids and pyramids.
