ShareNeurotransmitters are chemicals that are used to relay, amplify and modulate electrical signals between a neuron and another cell.

Substances that act as neurotransmitters can be roughly categorized into three major groups: (1) amino acids (primarily glutamic acid, GABA, aspartic acid & glycine), (2) peptides (vasopressin, somatostatin, neurotensin, etc.) and (3) monoamines (norepinephrine NA, dopamine DA & serotonin 5-HT) plus acetylcholine (ACh).
The major "workhorse" neurotransmitters of the brain are glutamic acid (=glutamate) and GABA.
