The first four of these equations are the differential equations which govern
the system's behavior. The many computer simulations of the H and H model
involve programs that repeatedly step through those first four equations (see
Fodor, 2005, for one example).
Equation [26] is then applied to the action potential. We are most interested
in the 'propagated action potential,' as distinguished from a uniform membrane
