Abstract
Interaction of skin and core temperatures in control of heat production were studied. Short goats with intravascular heat exchangers to control core temperature were immersed to the neck in a circulating water bath to clamp skin temperature. With bath temperature kept constant at levels between 32-42.degree. C, core temperature was varied between 40-36.degree. C and changes in heat production were measured. Falling core temperature shivering occurred at all bath temperatures and heat production rose. Threshold of core temperature below which heat production increased varied inversely with level of skin temperature. Even at bath temperature of 42.degree. C slope at which heat production rose exceeded -5 W/kg per .degree.C. In the goat, even high skin temperatures did not abolish central impulse to shiver which was caused by low core temperature. Heat production control, skin temperature and core temperature provided linear and independent inputs which did not replicate any known relationship between temperature and discharge frequency of thermoreceptors.
