Behavioral characterization of amygdala involvement in mediating intra-accumbens opioid-driven feeding behavior.

30 Jul 2009 The present experiments were conducted to provide a more detailed behavioral analysis of the dissociable roles of the basolateral (BLA) and central nucleus (CeA) of the amygdala in mediating intra-accumbens (Acb) opioid-induced feeding of a high-fat ... Read more...

Opioid mu-receptors in medullary raphe region affect the hypoxic ventilation in anesthetized rats.

22 Jul 2009 Opioids can attenuate the peripheral chemoreceptor-mediated hypoxic ventilatory response (HVR) by acting on central mu-type opioid receptors. Since the medullary raphe region (MRR) expresses abundant mu-receptors and participates in modulating HVR, ... Read more...

Induction of synaptic long-term potentiation after opioid withdrawal.

8 Jul 2009 mu-Opioid receptor (MOR) agonists represent the gold standard for the treatment of severe pain but may paradoxically also enhance pain sensitivity, that is, lead to opioid-induced hyperalgesia (OIH). We show that abrupt withdrawal from MOR agonists ... Read more...
