BEHAVIORAL THERMOREGULATION IN RESPONSE TO HEATING AND COOLING OF THE HYPOTHALAMIC PREOPTIC AREA OF THE DOG.

Abstract

Cooling the hypothalamic-preoptic tissue to a temperature of 32 C causes greatly increased motivation in the dog to press a bar for heat in a cold environment of -5 C. Heating the same region of the brain to a temperature of 42 C causes almost complete suppression of bar pressing. These strong behavioral responses to changes in hypothalamic temperature take place with only very slight changes in rectal temperature. There appears to be an active pathway, between the hypothalamic-preoptic region and the sensory cortex, capable of thermoregulatory function and sensitive to both heat and cold in the hypothalamic-preoptic region.
