摘要：

Arctic sculpins of the genus Myoxocephalus adapted to water at 5°C escaped from warm water at 20°, 16°, and 12°C when their deep-body temperatures increased from an initial 5°C to about 8°C. Heating parts of the forebrain with water at 25°C circulating through a pair of thermodes astraddle rostral parts of the forebrain shortened the time spent in the warm water and lessened the incease in deep-body temperature before exit from the warm water. Cooling the forebrain to about - 1°C caused a large increase in the body temperature and sometimes suppressed the escape from the warm water.
