taken in conjunction with the results of in vitro studies on the specificity of action of dalpha ? and related substances , these observations suggest that certain synaptic excitations in the spinal cord are mediated by an excitatory amino acid transmitter , and that this transmitter interacts with receptors which are activated selectively by nmda , less selectively by other amino acids , including l-aspartate , and probably only slightly by quisqualate , kainate and ( exogenous ) l-glutamate .
