Action potential

Name: Action potential
Description: A large, brief, all-or-nothing, regenerative electrical potential, that propagates along the axon, muscle fiber, or some dendrites. Action potentials are usually generated at the axon hillock and propagate uni-directionally down the axon. Adapted from Nicholls, Martin and Wallace 3rd edition.
Synonym(s): Firing, Spike, Axonal Action Potential
Abbreviation: AP
Has role: Electrophysiology concept
Super-category: Membrane potential
URL: ModelDB:3645
