Aspartic acid has been regarded as an excitatory transmitter for many years, but the extent of its role as a transmitter is unclear.,CSP: family of agonists for neural glutamate receptors which have been used to identify receptor subtypes and to model excitotoxicity and excitatory neural transmission.
