THE PERFORMANCE OF SMALL MAMMALS AT LOW BODY TEMPERATURES.
Abstract
Trained performance, therefore, stubbornly persists through a large depression in body temperature. Nevertheless, it is a temperature-dependent phenomenon, with suppression occurring in a non-linear fashion. Trained performance stops within narrow body temperature ranges for individuals of the same species performing the same task, and within a wider but still narrow range for the six species studied. The report also contains brief summaries of research on blood pressure, heart rate, fractional distribution of cardiac output to the brain, righting reflexes, and spontaneous locomotor activity during progressive hypothermia in the unanesthetized rat. In addition, the report summarizes studies on the effect of Dimethylsulfoxide on cooling rates, oxygen consumption, behavioral temperature regulation, heart rate, and cardiac arrest during progressive hypothermia in unanesthetized small mammals. The distribution of Dimethylsulfoxide in the tissues of the unanesthetized hypothermic rat is also discussed. (Author)
