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. gamma-aminobutyric acid /gam·ma-ami·no·bu·tyr·ic ac·id/ (gam″ah-ah-me″no-bu-tir´ik) γ.
GABA (gamma-aminobutyric acid) A neurotransmitter that slows down the activity of nerve cells in the brain. Mentioned in: Central Nervous System Depressants 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. γ-aminobutyric acid an amino acid that is one of the principal inhibitory neurotransmitters in the central nervous system.

Soellner and Nunez tested the cells' responses to various chemicals that brain cells use to communicate, such as the neurotransmitters gamma-aminobutyric acid and glutamate. As for baclofen, a potent gamma-aminobutyric acid (GABA) agonist frequently used by people with SCIs to control spasticity, recent studies have demonstrated its antitussive activity[3] and inhibition of bronchial hyperresponsiveness to methacholine in people with quadriplegia. These receptors, when bound to a chemical called gamma-aminobutyric acid, cause a slowing of nerve transmissions in the brain. |
