  • Title: Various aspects of feeding behavior can be partially dissociated in the rat by the incentive properties of food and the physiological state.
    Author: Barbano MF, Cador M.
    Journal: Behav Neurosci; 2005 Oct; 119(5):1244-53. PubMed ID: 16300432.
    Abstract:
    The authors investigated the role of food incentive properties and homeostatic state on the motivational, anticipatory, and consummatory aspects of feeding. Behavioral tests were carried out on food-sated and food-restricted rats that were presented with 2 kinds of food differing in their palatability level. Both food-sated and food-restricted rats consumed large quantities and were highly motivated when presented with very palatable food. In contrast, only food-restricted rats developed anticipatory responses, regardless of the kind of food presented. These data suggest that food incentive properties play a key role in the control of consummatory and motivational components of feeding but seem less involved in the regulation of anticipatory behavior.
