Abstract：
:Persistent autonomic disturbances following stressful events suggest that the rhythmical nature of homeostatic functioning may be disrupted by these experiences. We assessed the effects of two different stressors on circadian and ultradian rhythms of Long-Evans rats by using nonlinear multi-oscillator cosinor analysis. Heart rate and intraperitoneal temperature were monitored continuously in 5-min intervals in two groups of animals via radio-telemetry for 15 days after surgery (n = 9) and 15 days following social defeat (n = 6). Circadian amplitude of heart rate and temperature increased significantly for the first nine days of the recovery from surgery but only circadian temperature amplitude increased following social defeat. Circadian acrophase of temperature but not heart rate changed significantly for a similar period following the surgery but not after the social defeat. A mathematical model incorporating the first five harmonics of the circadian rhythm was found to fit the data significantly better than a circadian model alone with rhythms of 3 and 5 cycles/day in temperature and heart rate entraining significantly to the light-dark schedule. Full recovery of the circadian and ultradian rhythms did not occur until a minimum of nine to twelve days after surgery or social defeat. The results suggest that rhythms with multiple periodicities are involved in homeostatic functioning and that models incorporating these rhythms may aid in understanding an organisms adaptive response to surgical intervention and social defeat, long after the challenges have terminated.
