Gaba Health Dictionary

The abbreviation for gammaaminobutyric acid, a neurotransmitter. GABA controls the flow of nerve impulses by blocking the release of other neurotransmitters (e.g. noradrenaline and dopamine) that stimulate nerve activity. GABA activity is increased by benzodiazepine drugs and anticonvulsants.

GABA, or gamma aminobutyric acid, is an amino acid (see AMINO ACIDS) that occurs in the central nervous system, mainly in the brain tissue. It is a chemical substance that transmits inhibitory impulses from nerve endings across synapses to other nerves or tissues.

see gamma-aminobutyric acid.
