finally , the potent protection against h.p.n.s . by 2-amino-phosphonoheptanoic acid , an antagonist with preferential action against excitation produced by aspartate and n-methyl-d-aspartate , provides the first evidence that enhanced excitatory amino acid neurotransmission may have an important role in the h.p.n.s .
