The role of the hypothalamic and skin temperatures in controlling the thermal response of a resting animal was studied by measurements of 1 hypothalamic, rectal, ear skin and trunk skin temperatures on the resting dog and rhesus monkey hypothalamic temperature only in hot, neutral and cold environments and 2 the thermal and metabolic responses of a dog while holding hypothalamus at approximately 38.7 C by means of six thermodes surrounding the hypothalamus and perfused with water. The results indicate that the parameters involved in temperature regulation must include more than skin and hypothalamic temperatures since an animal engaged in normal regulation would exhibit very different responses for the same hypothalamic temperature when exposed to different ambient temperatures or would exhibit the same responses at widely different hypothalamic temperatures at different times, depending on whether asleep or awake.
