The results show that the hyperalgesia of OFQ and its antagonization on AA in PAG are dose-related. OFQ in PAG decreases the enhancing effect on AA induced by ohlnefentanyl, a selective μreceptor agonist.

The activation of NRM neurons by electroaeupuncture was eliminated after decerebration at superior colliculus level, indicating that this effect of EA depends mainly on the supra-midbrain structure. Furthermore, all treatments including AR isolation, disconnection of #beta#-endorphinergic tract and micrpinjection of naloxone or anti-#beta#-endorphin serum into PAG, would make the effect of EA disappear. Thus, it is the #beta#-endorphinergic pathway between AR and PAG-NRM system that mediates the major excitatory effect of EA on NRM.

The results suggest that habenula may serve as a relay in the descending pathway of analgesia from nucleus accumbens to PAG, using ME in habenula and ME and GABA in PAG as neurotransmitters.

Thus, the analgesic effect of morphine injected into PAG was significantly attenuated by β-EP AS injected into the nucleus accumbens, and vice versa. This antagonistic effect was totally abolished by lesioning of the ARH. Moreover the analgesic effect of morphine injected into nucleus accumbens could be blocked byβ-EP AS administered te amygdala or habenula.

It is possible that morphine applied to VLO depresses the GABAergic interneuronal activities that tonically inhibits the VLO output neurons projecting to PAG, leading to activation of the PAG-brainstem descending inhibitory system which depresses the nociceptive inputs at the spinal cord level.
