ABSTRACT
The rhythms of short-term arousal episodes, associated with normalization of low body temperature, were studied in hibernating Erinaceus roumanicus. The episodes of body temperature recovery during hibernation were 1.7 times more incident during the acrophase of 4.058-day rhythm of glucocorticoid hormones, detected previously, than during the batiphase of this rhythm. Ultradian rhythm of arousal episodes conformed to a 4-h biorhythm the maximum number of body temperature resumption episodes was recorded at 00.00-01.00, 04.00-05.00, 08.00-09.00, 12.00-13.00, 16.00-17.00, and 20.00-21.00. These data indicated that in mammals the mechanisms of infradian and ultradian rhythm maintenance were stable and did not depend on body temperature or were determined by external factors with periods of 4.058 days and 4 h.
