[Change in the infradian rhythms of some physiological processes, controlled by the epiphysis, in epiphysectomized rats exposed to a super low frequency variable magnetic field]

The infradian rhythmic of the behavioral parameters, urination, body mass and temperature in epiphysectomized rats exposed to a variable magnetic field of a frequency of 8 Hz and induction of 5 microT influence was studied. It was found that the removal of epiphysis leads to the reorganization of power spectra of biorhythms, a rise of their amplitudes, and the development of desynchronosis. Further exposure of epiphysectomized rats to a variable magnetic field partially normalizes the amplitude-phase relations and decrease the disbalance of the processes. These data indicate the important role of epiphysis in the magnetoreception and formation of the temporal structure of the organism and suggest the existence of other structures sensitive to variable magnetic field.
