Abstract :
Potentials within and on the surface of a finite cylindrical volume conductor due to a single active nerve fiber along its center have been calculated by solving Laplace´s equation using a relaxation model. The results have enabled the variation of the potential that would be recorded from a surface electrode to be estimated for differing nerve depths and conduction velocities.
