γ-Aminobutyric acid (GABA) is the chief inhibitory neurotransmitter in the mammalian central nervous system. It plays an important role in regulating neuronal excitability throughout the nervous system. In humans, GABA is also directly responsible for the regulation of muscle tone.In insect species GABA acts only on excitatory nerve receptors.
While technically an
amino acid, GABA is rarely referred to as such in the scientific or medical communities, because the term "amino acid," used without a qualifier, refers to the alpha amino acids, which GABA is not, nor is it incorporated into proteins.
spastic diplegia in humans, GABA absorption by some nerves becomes damaged, which leads to hypertonia of the muscles signaled by those nerves.

The GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid (GABA), the chief inhibitory neurotransmitter in the vertebrate central nervous system. There are three classes of GABA receptors: GABAA, GABAB, and GABAС. jea
GABAA and GABAС receptors are
ligand-gated ion channels (also known as ionotropic receptors), whereas GABAB receptors are G protein-coupled receptors (also known as metabotropic receptors).
