γ-a·mi·no·bu·tyr·ic ac·id (GABA, γ-A·bu),

(ă-mē'nō-bū-tēr'ik as'id),

γ-aminobutyric acid

/γ-ami·no·bu·tyr·ic ac·id/ (GABA) (-bu-tēr´ik) the principal inhibitory neurotransmitter in the brain but also occurring in several extraneural tissues, including kidney and pancreatic islet β cells. Released from presynaptic cells upon depolarization, it modulates membrane chloride permeability and inhibits postsynaptic cell firing.
