Inhibitory nerves

WebbGlutamate is the primary excitatory transmitter in the central nervous system. Conversely, a major inhibitory transmitter is its derivative γ-aminobutyric acid (GABA), while another inhibitory neurotransmitter is the amino acid called glycine, which is mainly found in the spinal cord. Many neuromodulators, such as dopamine, are monoamines. WebbThe term GABA refers to the simple chemical substance -aminobutyric acid (NH 2 CH 2 CH 2 CH 2 COOH). It is the major inhibitory neurotransmitter in the central nervous system. Its presence in the brain first was reported in 1950 (Roberts and Frankel, 1950a).
