In the present study , the interactions between this mGlu 5 PAM and the NMDA receptor were explored further by assessing the effects of LSN2463359 against some of the motor , instrumental and cognitive effects induced by the non - competitive NMDA receptor antagonists PCP and MK - 801 , the competitive NMDA receptor antagonist SDZ 220 , 581 and the GluN2B selective NMDA receptor antagonist , Ro 63 - 1908 .
