Excitatory amino acid receptors

Professor Johnston has alluded earlier in this volume to the complexity of the GABA-activated systems. Although considerably less well understood, it is probable that the glutamate-aspartate receptors will prove to be as complicated and as diverse as those activated by GABA, and as quantitatively important. Given these indications, their involvement in the etiology of Parkinson's disease and other neurological disorders is eminently probable.
