whereas polysynaptic excitation of interneurones was readily and reversibly depressed by 2-apv , 2-aph , beta daa , gamma dgg and 2,3-pda , all of which also reduced excitation by nmda ( and l-aspartate ) more than that by quis ( and l-glutamate ) , no selective antagonism of monosynaptic excitation could be demonstrated .
