font face="AdvP497E2" size="1"> The development of restraint stress-induced sensitization to the locomotor stimulating effect of morphine (2 mg/kg i.p.) was investigated. In experiment 1, both a single restraint session (2 h) and a repeated restraint stress (2 h per day for 7 days), similarly enhanced the effects of morphine on motor activity. In experiment 2, we observ
