Although N-methyl-D-aspartate (NMDA) receptor antagonists clearly attenuate the development of tolerance to the antinociceptive effects of opioids, it is not clear whether they also alter acute opioid-induced antinociception. The present study was designed to assess NMDA/opioid interactions in C57BL/6 mice

Psychopharmacology, 170(4), 335-342 (2003-09-19)
Drugs enhancing the GABA(A) and/or reducing the NMDA/glycine-B receptor activity produce an anxiolytic effect. Regarding the former drugs (e.g. benzodiazepines), prior elevated plus-maze (EPM) test experience abolishes the trial 2 anxiolytic activity, a phenomenon referred to as "one-trial tolerance" (OTT).

Conditioned taste aversion (CTA) is a form of associative learning in which the pairing of a taste with a toxin causes an animal to avoid the taste. NMDA receptor mediated neurotransmission has been implicated in CTA, but the role of

(+)-HA-966, a partial agonist at the glycine/NMDA modulatory site, significantly reduced i.v. cocaine self-administration in a fixed-ratio (FR) schedule. Since this effect was observed studying only one dose of cocaine and considering the characteristic bell-shaped curve generated by cocaine in

Using the C-fibre reflex as a nociceptive response elicited by a wide range of stimulus intensities in the rat, we recently reported that a single treatment with (+)-HA966, a glycine site-specific NMDA receptor antagonist: (1) potentiates morphine antinociception; and (2)
