AMPA but not NMDA receptor transmission in VTA is required for cue-induced reinstatement. a VTA AMPA antagonist: cueinduced reinstatement is shown after bilateral VTA microinjections of the AMPA antagonist CNQX (0.7 and 0.35 mM). b VTA NMDA antagonist: cue-induced reinstatement behavior is shown after bilateral VTA microinjections of the NMDA antagonist AP-5 (1.6 and 0.8 mM). Pressing in late extinction is shown at the left in both panels for comparison. Inactive lever presses on reinstatement days are shown with black bars. *Different from vehicle reinstatement day, p<0.05
