Abstract
NEUROPHYSIOLOGICAL experiments suggest that several aminoacids, especially glycine and glutamic, aspartic and gamma-aminobutyric (GABA) acids, are neurotransmitters in the central nervous system1–3. But careful subcellular4,5 and regional studies6–8 have not provided supporting neurochemical evidence, because ammo-acids, with the possible exception of GABA, also have general metabolic functions in nervous tissue.
