action potential

Term Information

Accession
GO:0001508
Name
action potential
Ontology
biological_process
Synonyms
None
Alternate IDs
None
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. Source: GOC:dph, GOC:tb, GOC:go_curators, ISBN:978-0-07-139011-8
Comment
Action potentials typically propagate across excitable membranes. This class covers both action potentials that propagate and those that fail to do so.
