Model of the effect of 4-aminopyridine at the level of potassium channels of the giant axon of the squid, Logigo forbesi L.]

Most of the effects of 4-aminopyridine on the potassium conductance of the giant axon of the Squid can be explained in terms of a simple model based on the physicochemical properties of the molecule and what is known about the structure of the potassium "channels".
