Abstract
The study monitored the long-term body temperature (BT) oscillations of C57BL/6 mice and outbred starlings (Sturnus vulgaris) to compare them with fluctuation in decay rate of radioactive natural 40K isotope. The spectrum analysis revealed simultaneous changes of the predominant periods in BT spectra of the animals and those in fluctuation in 40K decay rate. A positive correlation was established between BT dynamics and fluctuation in decay rate. The superposed epoch analysis revealed predominant coincidence of the moments of BT and fluctuation in 40K decay rate. The novel data indicate association between BT ultradian rhythms with quasirhythmic variations of fluctuation in 40K decay rate.
