The authors of this paper provide experimental proofs that extremely low frequency magnetic fields can induce animal behavioral changes and synchronizations in respect to their infradian rhythms (that is rhythms that span various days).
They choose an exposure to a frequency in the range of the main Schumann resonance frequency although much more intense (5000000 times more intense) but less intense than the geomagnetic field (10 times less intense).
Daily 3h exposure to this magnetic field modify the dynamics of behavioral reactions showing a synchronism in rats even from different individual–typological groups (rats were divided into 3 groups depending on their activity intensity). An analysis of the specter structure shows an undergoing similar distribution of the periods and amplitudes on all those animals.
Authors found that daily effect of the magnetic field with a frequency of 8 Hz provides the synchronizing effect on time organization of neuronal processes controlling animal behavior, this in turn results not only in the appearance of similar periods in integral rhythms of behavioral reactions, but also in some agreement of their phase characteristics The effects include the clusterization of short periods within the 2–5 day value area.
" This (i) shows the common system reaction mechanisms that the organisms of animals have to the effect of a certain factor and (ii) is evidence of the synchronizing influence of the daily influence of magnetic fields of extremely low frequencies on populations of organisms with initially different biorhythmic types. It has been concluded that the stable variations of electromagnetic background, including natural, can serve as a timer for biorhythms in a wide range of periods."
