Intrinsic excitability

http://learnmem.cshlp.org/content/10/6/456 WebThe term excitability means that when a cell is sufficiently stimulated, it can react with a brief electrical discharge, called an action potential. The action potential (the nerve impulse) travels along the axon and is a major component in the communication among nerve cells and between nerve cells and other cells of the body.
