Statistical and dynamical analysis of circadian rhythms

Time series of core temperature in golden hamsters with or without access to a running wheel were analyzed using statistical tools and Dynamical Systems theory. Although the statistical analysis did not show any striking differences between the two groups (other than clearer spectra in the case in t...

520 3 |a Time series of core temperature in golden hamsters with or without access to a running wheel were analyzed using statistical tools and Dynamical Systems theory. Although the statistical analysis did not show any striking differences between the two groups (other than clearer spectra in the case in the animals with access to wheels), a clear dynamical difference was found. The circadian temperature of hamsters with access to wheel running exhibited fewer degrees of freedom than those without access to them (1728 vs 11548). Thus, it may be argued that wheel running synchronizes the circadian organization of hamsters. © 1994 Academic Press Limited.  |l eng
