The longest periods of physiological rhythms can be formed from shorter periods with the aid of simple circuits similar to a trigger and composed of neurons. This assumption will contradict, however, the fact, that at least, 11 EEG rhythms of a man have nonmultiple frequencies and appear as statistically independent oscillating processes. However it is not possible to deny the possibility of deviations from this rule for the lowest periods.
It is known that the electrical rhythms of the brain are synchronized with external light and sound signals, and are also under the influence of electrical and magnetic fields. In work  it has been shown that the EEG and EKG of a man to a known degree are synchronized with sounding music. This synchronization is especially distinct in lovers of jazz music. It is possible that our love for music is associated with the mechanisms for synchronizing the biological processes. It is possible that "good music" - that music at which the brain is maximally unloaded from cares with regard to the synchronization of a complex system. In another work it has been said  that under the influence on both eyes by discontinuous light with non- multiple frequencies heavy disturbances in the nervous system occur.
It is natural to propose in this case the disturbance of synchronizing on a number of rhythms, disorder of the biological clock, short duration failures in the code, large errors in the system for tracking the alpha-rhythm frequency. All this on the whole also leads to the death of experimental animals. Apparently, the organism compensates for noise, if it is alone. But if through each eye individually two independent interferences penetrate into the brain, then compensation does not occur.
In conclusion it follows to recall the words of the known scientist A. S. Zalmanov : "there occur cases - and they are frequent - when the death of a patient cannot be explained either by the development of an unhealthy phenomena, or by insufficiency in the most important forms of activity of the organism (breathing, blood circulation, excretion), or by serious premortal complications. There remains a probable hypothesis: this breakdown of the synchronous enrhythmia? (i.e., of normal rhythmics. - S. L.).
