Figure 2. Dendritic dimensions of nonpyramidal cell subtypes.

(a) upper panel: The cross-sectional areas of dendritic segments plotted against their distances from the soma. Large dendrites are frequently found near somata, whereas only small dendrites are observed at distal locations. Some small dendrites were also found in proximal locations. lower panel: cross-sectional areas of dendritic segments shown with trajectory lines for some trees (M2, M3, F4 – F6, D1, D2, L2 – L4). At the dendritic bifurcations, the daughter branches split into larger (black circle) and smaller (white circle) segments. (b) For all nonpyramidal cells tested, dendritic cross-sectional areas were well correlated with the total dendritic length distal from the point of reference.
