Analysis of models for extracellular fiber stimulation

Abstract
This paper presents the mathematical basis for analysis as well as for the computer simulation of the stimulus/response characteristics of nerve or muscle fibers. The results follow from the extracellular potential along the fiber as a function of electrode geometry. The theory is of a general nature but special investigations are made on monopolar, bipolar, and ring electrodes. Stimulations with monopolar electrodes show better recruitment characteristics than ring electrodes.
