Naloxone-induced hypoalgesia: evidence from the formalin test.


Two experiments examined the hypoalgesic effects that accrue from pairing exposure to a heat stressor with the opioid antagonist naloxone. Experiment 1 confirmed that rats given separate exposures to a heated floor and to naloxone are hypoalgesic when then tested on that floor. Further, the results confirmed that pairing the initial exposure to the heat… (More)
