- Action potential : Action potential refers to a brief change in electrical voltage that occurs between the inside and the outside of an axon when a neuron is stimulated; it serves to produce an electrical impulse.
Other /More definition:
Action potential refers to a pulselike electrical discharge along a neuron. Sequences of linked action potentials are the basis for the transmission of neural messages.
Likewise, Action potential is defined as the rapid increase in positive charge in a nerve fiber that travels down the fiber. Also called the nerve impulse.
