[The initiation of cold shivering during the local heating of the rat hypothalamus under immersion hypothermia].

Abstract

A local artificial heating of the hypothalamic centre of thermoregulation in rats subjected to immersion cooling to a deep hypothermia activated a shivering. The data obtained suggest that one of the reasons of disorders in the organism thermoregulatory functions under conditions of a deep hypothermia involves a direct effect of the cold upon the thermoregulation centre in the hypothalamus.
