that these sites are associated with n-methyl-d-aspartic acid ( nmda ) receptors is indicated by the observations that [ 3h ] glycine binding is selectively modulated by nmda receptor ligands and , conversely , that several amino acids interacting with the glycine sites increase [ 3h ] n- [ 1- ( 2-thienyl ) cyclohexyl ] piperidine ( [ 3h ] tcp ) binding to the phencyclidine site of the nmda receptor .
