title: Quisqualic acid excitation of cortical neurones is selectively antagonized by streptomycin.
abstract: Although evidence exists for at least 3 kinds of excitatory amino acid receptor in the CNS, responding to N-methyl-D-aspartic acid, kainic acid and quisqualic acid, respectively, only antagonists at the former two sites are currently available. It is now reported that when applied by microiontophoresis to neurones in the rat cerebral cortex, excitatory responses to quisqualic acid can be selectively reduced by streptomycin.
