GABA neurons

Gamma-aminobutyric acid neurons (GABA) in the brain

Most neurons throughout the grey area in the central nervous system (CNS) are capable of either producing and/or responding to gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter.


Higher GABA concentrations are found in the purkinje cells in the cerebellum and in the basal ganglia. Also the astrocytes in the cerebral cortex produce GABA.
