Amino acid neurotransmitters inhibitory

GABA (y-aminobutyric acid) The major inhibitory amino acid neurotransmitter of the CNS. 

The amino acid neurotransmitters are subdivided into primarily excitatory (glutamate, aspartate) and inhibitory (y-aminobutyric acid, GABA, glycine) types. 

There are more than 10 billion neurons that make up the human nervous system, and they interact with one another through neurotransmitters. Acetylcholine, a number of biogenic amines (norepinephrine, dopamine, serotonin, and in all likelihood, histamine and norepinephrine), certain amino acids and peptides, and adenosine are neurotransmitters in the central nervous system. Amino acid neurotransmitters are glutamic and aspartic acids that excite postsynaptic membrane receptors of several neurons as well as y-aminobutyric acid (GABA) and glycine, which are inhibitory neurotransmitters. Endorphins, enkephalins, and substance P are considered peptidergic transmitters. There are many compounds that imitate the action of these neurotransmitters.

The excitotoxic index was developed by our group as a composite descriptor of excitatory/inhibitory amino acid neurotransmitter balance as measured by microdialysis in the brain s extracellular space (66,102). This index is defined as ... 

GABA is an inhibitory amino acid neurotransmitter of brain interneurons and other cerebral neurons. The enzyme glutamic acid decarboxylase catalyzes the synthesis of GABA from glutamate. GABA is stored in presynaptic vesicles and binds to either GABA-A or GABA-B receptors upon release.
