Abstract
Mammalian hibernation is characterized by the alternation of prolonged periods of hypothermia and spontaneous arousals with a temporary return to euthermia. Of special interest to the physiology of effectors of thermogenesis are the following points:
-
a)
In the second part of the arousal process, the metabolic rate reaches 6 to 8 times BMR, with a body temperature about 10 °C lower. Enzymatic adaptations provide for the maintenance of normal reaction rates and regulatory potentials at low temperatures, but how very high thermogenetic rates can be achieved still remains largely unexplained.
-
b)
Entrance into hibernation involves a resetting of the hypothalamic thermostat to a lower level, but this is probably not the only intervening regulation. Evidence is presented in favor of a control of thermogenesis at the effector level, in terms both of baseline levels and of loop gains. One likely control factor is acid-base state, which can be changed rapidly and reversibly by ventilation and is characterized by a strong acidosis in hibernation.
