[Temporal organization and information in biological systems].

Analysis of the available chronobiological data leads to the following conclusions about the role of biorhythms in the informational interface in living systems: (1) temporal organization of living systems is the main channel of informational interface in organism (the principle of the bond between information and temporal organization); (2) biorhythms or, more accurately, temporal organization of type one postulates the fulfillment of one of the fundamental statements of the general information theory, i.e., correspondence of information to the substratum of its application (the correspondence principle); (3) the biorhythm phases can either unidirectionally strengthen, weaken or realize in different directions the biological potentials of information brought into organism by one and the same material carrier (the principle of amplification, attenuation or inversion of informational potential by biorhythm); (4) biorhythm is the mechanisms driving the transformation of continuous informational signal, if any, into discrete, i.e. the one apt to fulfil a substantial informational stimulus (the quantification principle); (5) as an oscillating reiterative process responsible for reproduction of a biological phenomenon or a biosystem state within nearly equal periods, biorhythm can be viewed as one of the mechanisms of propagation of information in biosystem (the multiplication principle); (6) reproduction of information through biorhythm is one of the universal mechanisms of information survival in biosystem (the information survival principle); (7) aggregation of biorhythms with different periodicity of the same function, i.e. temporal organization of type two, makes it possible for living system to cover a wide frequency spectrum of perception, transmission and replication of signals carrying bio-information with similar semantics, and to make its differential choice when necessary (the principle of optimality of differential choice in perception, transmission and replication of information); biorhythms of an integral whole (temporal organization) is the mechanism underlying the informational interface between biological time of living system and physical time of its environment (the principle of informational interface between biological and physical time).
