Abstract:
Large baseline differences were found in open field activity and rearing behavior between 2 psychogenetically selected rat lines, as well as differences in the effects of peripherally administered morphine (2,4 and 10 mg/kg) on those behaviors and on body temperature. The 2 lines also showed different capacities of tritiated DAGO binding to preparations of striatal membranes.
