Title: Stabilization of the brain temperature in mammals of different body size under various ambient temperatures

Description:

Brain temperature (T Br) was measured with accuracy 0.05°C in 9 species of mammals weighing from 7 to 3850g. Experiments were performed at ambient temperatures (T A) ranging from 0 to 35°C. There was found a negative correlation between body size and the dependence of brain temperature on ambient temperature. However, the pattern of changes of T Br after cold exposure of animals, suggested that this dependence did not result from low thermal inertia. Results suggested that changes of T A may be an adaptation to thermal economy, even at the cost of accuracy of homeothermia of the brain.
