Popis: | This study shows that single (15 mg/kg) or binge (3×15 mg/kg) cocaine administration increases c-fos mRNA levels, but only binge cocaine administration increases preprodynorphin mRNA levels in the caudate/putamen of Fischer rats. This increase in both c-fos and preprodynorphin mRNA levels is attenuated by the noncompetitive NMDA antagonist MK-801 (0.25 mg/kg), suggesting a preferential role for NMDA receptor co-activation in cellular events leading to cocaine-induced behaviors. |
