Abstract

Behavioral sensitization to a single morphine injection is a unique model to study the neuroanatomical substrates of long-lasting behavioral plasticity associated with opioid reward and abuse. Earlier observations have demonstrated that septal nuclei are critically involved in the processes of reward, learning and memory. In the present study, we investigated the effects of septal nuclei lesions on behavioral sensitization to a single morphine injection, morphine induced conditioned place preference and antinociception in rats. Behavioral sensitization was established by a single injection of 3-30 mg/kg morphine in rats. Bilateral electrical lesions of septal nuclei were carried out 7 days b..
