THERMAL REGULATORY RESPONSES OF UNANESTHETIZED DOGS DURING HYPOTHALAMIC TEMPERATURE MEASUREMENT AND STIMULATION
Abstract
The role of the hypothalamic and skin temperatures in controlling thermal response of a resting dog was studied by two methods: (1) measurements were made of hypothalamic, rectal, ear skin, and trunk skin temperatures of the dog in winter fur in hot, neutral, and cold environments; respiration rate and shivering were observed; (2) a thermal clamp (six thermodes surrounding the hypothalamus and perfused with water to hold it at approximately 38.7 C) was used to measure thermal and metabolic responses of the resting, fasting dog during exposure to a wide range of temperatures. Although skin and hypothalamic and skin temperatures and the motor responses could not be established.
