Abstract

This study examined the extent to which low doses of morphine paired explicity with high doses would gain associative control over tolerance development in rats. Tolerance development was assessed by evaluating dose-response curves to the analgesic effects of morphine on the tail-flick test. The results indicated that tolerance development was not influenced by the pairing of low doses with high doses.
