The integration of visceral information in the control of feeding

Electrophysiological evidence exists for sensitivity to many aspects of nutrient depletion and repletion at all levels of the viscera and beyond. Behavioral evidence suggests that feeding is sensitive to manipulations at all of these levels, while at the same time showing that no one site or nutrient is required for feeding regulation. This suggests that one must look at the sequence and interdependence of events occurring from ingestion to ultimate tissue distribution in order to understand the control of food intake.
