γ-aminobutyric acid

 (GABA) [gam″ah-ah-me″no-bu-tēr´ik]
an amino acid that is one of the principal inhibitory neurotransmitters in the central nervous system.

gamma-aminobutyric acid

 [gam″ah-ah-me″no-bu-tir´ik]
γ-aminobutyric acid; see under A.

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

(ă-mē'nō-bū-tēr'ik as'id),
4-aminobutyric acid; a constituent of the central nervous system; quantitatively, the principal inhibitory neurotransmitter. Used in the treatment of various neurologic disorders (for example, epilepsy).

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.

n. Abbr. GABA
An amino acid, C4H9NO2, that is not found in proteins, but occurs in the central nervous system and is associated with the transmission of nerve impulses.

gamma-aminobutyric acid (GABA)

an amino acid that functions as an inhibitory neurotransmitter in the brain and spinal cord. It is also found in the heart, lungs, and kidneys and in certain plants.
