title: Opiate effects on aversive midbrain stimulation in rats.
abstract: Morphine blocked decremental bar pressing of rats to escape electrical stimulation of aversive midbrain sites. These sites included the dorsal central gray area (DCG), the ventral reticular formation (VRF) and the lateral tegmentum (LT). Naloxone, which had no effect alone, blocked the morphine effects of all three aversive sites.
