Figure 5

Polar histograms showing angular distributions of dendritic lengths projected to the transverse plane. Full circle around somata (S) was divided into 40 degree angle intervals starting with the dorsal direction (0°), the total lengths of dendritic branches were measured within these intervals and averaged over MNs within the same part of the cord. Mean dendritic lengths were represented on a relative scale by the length of a line drawn from the soma in the given direction and finally end points of these lines were interconnected (gray line for the cervical MNs and black line for lumbar MNs). The direction with the longest dendritic length was taken as 100% for the lumbar and cervical MNs separately. Ventromedial (VM) direction (120–160°), where significant segmental difference in angular distributions of dendrites was detected (Mann–Whitney-test, p < 0.05) is shaded in gray.
