<P> In neuroscience , glutamate refers to the anion of glutamic acid in its role as a neurotransmitter : a chemical that nerve cells use to send signals to other cells . It is by a wide margin the most abundant neurotransmitter in the vertebrate nervous system . It is used by every major excitatory function in the vertebrate brain , accounting in total for well over 90 % of the synaptic connections in the human brain . It also serves as the primary neurotransmitter for some localized brain regions , such as cerebellum granule cells . </P>
