Abstract

Hypothermia was induced by hypercapnic hypoxia in thirteen-lined ground squirrels, Citellus tridecemlineatus. When the squirrels were allowed to recover normal body temperatures at a 10°C ambient temperature, those with anterior hypothalamicpreoptic lesions took three to four times longer than normal controls to reach a body temperature of 35°C.
