title: [Hypothalamic self-stimulation during the abstinence syndrome in morphine-dependent rats].
abstract: Rats with lateral hypothalamic self-stimulation were treated chronically with morphine (30 injections in the course of 15 days) in doses increasing stepwise  from 20 to 120 mg/kg per injection. Morphine facilitated self-stimulation from the 9th injection. Both short-term abstinence (16-18 hours) and cessation of the narcotic resulted in inhibition of the response. Full suppression of self-stimulation occurred under the administration of nalorphine, morphine antagonist, in a dose of 5 mg/kg.
