Huxley and hodgkin
WebHuxley and Hodgkin's research was concerned primarily with the physicochemical analysis of the fundamental phenomena involved in the excitation in a peripheral nerve fiber and in the conduction of excitation along that fiber. Eccles extended their work to synapses. WebA system of four differential equations, such as the Hodgkin-Huxley model, is difficult to analyze, so that normally we are limited to numerical simulations. A mathematical analysis is, however, possible for a system of two differential equations.
