The distribution of kainate and quisqualate receptors in the rat cerebellum

Sensitivity of isolated Purkinje neurons from rat cerebellum to agonists of excitatory amino acids was studied. Kainate and quisqualate activated inward currents in the most studied neurons. NMDA and APB were ineffective. Distribution of kainate and quisqualate receptors was different. Currents activated by kainate and quisqualate were not additive. Hypotheses allowing one to explain the observed results were discussed.
