Low doses of sodium pentobarbital injected i.p. in satiated rats increased wet mash intake to approximately the level of a 24 hr food deprived animal. Intakes of quinine adulterated mash and a nonnutritive bulk substance were similar for the pentobarbital injected animals and for 24 hr food deprived animals. Further tests demonstrated that the drug potentiates pain-elicited aggression, but has no effect on running in an activity wheel. These data are incorporated in an hypothesis that increased arousal in the presence of a goal object is sufficient to elicit the consummatory response appropriate to that goal object.
