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...
