Ways to approximate current-distance relations for electrically stimulated fibers.
The behaviour of myelinated and unmyelinated fibers is simulated by a model for extracellular stimulation in order to confirm current-distance phenomena known from experiments. Lower and upper limits for cells stimulated with cathode current are calculated for unmyelinated fibers. In the case of myelinated fibers the threshold depends on the distance from the axon and from the nodes.
