| Research Abstract |
The core body temperature and the peripheral one are distinct parameters in physiological function. In this study, circadian variations of deep brain temperature were recorded in freely moving mice. Micro thermistor probes were inserted aiming either into unilateral hypothalamus and the surface in cortex. Brain temperatures were recorded from freely moving mice with wheel running activity. In parallel to nocturnal activity in behavior, circadian variation of brain temperature was clarified. Furthermore, an ultradian variation was obvious as well.：
