Table V.

Current distance constants estimated using the refractory interaction technique combined with geometric models of the overlap. Each result in the upper table is the average of to 6 measurements at different stimulus amplitudes. Each result in the lower table is the average of 8 to 9 measurement at different interelectrode distances. Each row is from a different randomized population of nerve fibers.
