Description

General description

γ-Aminobutyric acid is a chief inhibitory neurotransmitter, which is found in the cerebellum, hypothalamus, thalamus and hippocampus. It is formed via the decarboxylation of L-glutamate catalyzed by the enzyme, glutamic acid decarboxylase(GAD).

Biochem/physiol Actions

Major inhibitory neurotransmitter in brain; GABA_A and GABA_B receptor agonist; increases Cl⁻ conductance.
