the specific n-methyl-d-aspartate antagonist 2 -- amino-7-phosphonoheptanoic acid ( ap7 ) and the preferential quisqualate receptor antagonist glutamate diethyl ester ( gdee ) did not block lc responses to pgi stimulation , leading us to the tentative conclusion that eaas may operate primarily at a kainate-type receptor on lc neurons to effect excitation from pgi .
