摘要

In this chapter we meet the action potential, the fundamental electrical signalling mechanism used by the body. We introduce the cycle of ion movements associated with the generation of an action potential and the role of different ion gates. We then analyse the system of action potential generation in terms of a simple electrical circuit model.
