Circadian body temperature rhythm and behavior of rats in thermoclines
Physiology & Behavior
|January 1, 1986
Abstract:
When normal adult rats were allowed to choose among different ambient temperatures in a thermocline they selected temperatures about 224 degrees out of phase with their own intracranial temperature circadian oscillations. Without some subsidiary hypotheses, these results are difficult to reconcile with the idea that circadian body temperature rhythm is due to a cyclical shift in the set point temperature.
