General Information
Term action potential ID (Ontology) GO:0001508 (Gene Ontology)
Definition A process in which membrane potential cycles through a depolarizing spike, triggered in response to depolarization above some threshold, followed by repolarization. This cycle is driven by the flow of ions through various voltage gated channels with different thresholds and ion specificities.[ ISBN:978 ]
