Atropine effects on the intermediate stage and paradoxical sleep in rats.

abstract：:It has been suggested that anxiety may be a critical factor in certain forms of non-opioid environmental analgesia. In the present study, 5-min exposure to the elevated plus-maze test of anxiety (EPM) induced a mild, though enduring, elevation in tail-flick latencies in male mice. Pretreatment with the opiate antagoni...
