"The excitability of various regions of the spinal motorneuron can be specified by solving the partial differential equation of a nerve fiber whose diameter and membrane properties vary with distance. For our model geometrical factors for the myelinated axon, initial segment and cell body were derived from anatomical measurements, the dendritic tree was represented by its equivalent cylinder, and the current-voltage relations of the membrane were described by a modification of the Hodgkin-Huxley model that fits voltage-clamp data from the motorneuron. ..."

The example simulations produce results similar to those seen in
Figures 3, 5, 6, 7, and 8. Differences may be due to details of
antidromic stimulation not specified in the paper.

This example was prepared by Michael Hines.
