TEMPERATURE CHANGES IN THE RAT IN RESPONSE TO FEEDING.
Feeding activity in fasted rats resulted in an immediate increase in brain temperature and a decrease in rectal temperature. The temperature changes did not correlate with any specific property of the food nor with the amount eaten. The responses were judged to be the result of reflex vasomotor changes resulting in widespread shifts in the direction of blood flow. They were not related to the regulation of food intake.
