Figure 8

Comparison of somatopetal log attenuations of postsynaptic potentials. Attenuations of PSPs were computed from dendritic locations and averaged within 100 μm path distance ranges from the soma. Homogeneous (Rms = Rmd, part A and B) and inhomogeneous (Rms < Rmd, part C and D) soma-dendrite membrane models were used with 1.4 MΩ (A and C) and 5.0 MΩ (B and D) neuron resistances, where Rms and Rmd values were defined as described in the legend of Figure 7. A characteristic 1400–1500 μm distance, the limit of distance domains where attenuations in cervical (closed circles) and lumbar MNs (open circles) were significantly different were marked by vertical dotted lines. Many error bars are not visible due to their very low values.
