CNS weighting of sweet taste and internal signals was determined by matching food sucrose concentration and pulse frequency of hypothalamic stimulation to maintain a constant feeding bout. The slope of the derived power function, -0.260, indicates that changes in internal signals are weighted much more heavily than changes in sucrose concentration in determining feeding behavior. This is the first demonstration of a mathematical relationship specifying the relative weights of external and internal factors. The relative weights of these factors were not altered by taste-receptor anesthesia. This indicates that receptor desensitivity does not affect how information is processed centrally.
