Electrical signs in biocommunication

Abstract

We studied electrical information channel which effectively operates in living organisms of different evolutionary levels, from bacteria to humans. It was assumed that to clarify the functional significance of the electrical activity not only the oscillation frequency is essential, but also the temporal structure of their sequences, the specific pattern that determines the level of activity of an organism. We registered the electrical activity in the cyanobacteria Oscillatoria terebriformis and Geitlerinema sp, the yeasts Saccharomyces cerevisiae, the ciliates Paramecia caudatum, the leech Hirudo medicinalis, the mollusk Helix lucorum, the spawn of frog Rana temporaria and eggs of estuary shrimp Artemia salina. Spectral analysis using a fast Fourier transform and the autocorrelation analysis revealed that the patterns registered from the same object are numerous and have different structure. The patterns are stable and repeatable in registrations from different specimens of the same species. The same pattern is reproduced many times in one and the same object. Patterns identical in structure were found in biological objects of different evolutionary level. It is supposed that the temporal structures of the oscillatory activity are biologically conservative and may be biological constants unchanging in evolution.
