在大鼠下丘脑前部和后部植入热电棒，研究了其代谢产热和操作性体温调节行为。发现代谢与下丘脑前部温度（32 - 42°C）呈负相关，与下丘脑后部温度无关。另一方面，行为被发现与下丘脑前部和后部的温度呈负相关。因此，下丘脑前部的温度变化影响自主和行为的温度调节，而下丘脑后部的温度变化只影响行为的温度调节。
Metabolic heat production and operant thermoregulatory behavior were studied in rats with thermodes implanted into the anterior and posterior hypothalamus. Metabolism was found to be inversely related to anterior hypothalamic temperature (between 32 and 42°C) and not related to posterior hypothalamic temperature. Behavior, on the other hand, was found to be inversely related to both anterior and posterior hypothalamic temperature. Therefore, temperature changes in the anterior hypothalamus affect both autonomic and behavioral thermoregulation, whereas temperature changes in the posterior hypothalamus affect only behavioral thermoregulation.
