About possible low-intensive combined fields of various physical nature mechanisms of interaction with bioobjects

摘要

This work is devoted to the problem of treatment, analysis and modelling of tissue interactions with weak electromagnetic fields of extra high frequency (EHF) and transformed in tissue hypersound. The author makes an attempt to systematize the existing idea of possible mechanisms of millimetre & hypersound waves effects on the tissues and human functional state with the help of a noise-induced transitions model. The idea of noise-induced coherence in neural networks and of colored noise (not white noise) in the dynamics of aqueous protein solutions is used here as well. The author investigated the dynamics of large networks (or cluster) of N globally pulse-coupled biocells (biotissue's elements) in a noise-induced synchronized state. In summary, identical qualitative power spectra are reproduced by a simple oscillator model with global phase coupling, demonstrating that the excitable nature of the biocells is not crucial. Thus, these spectra should be present in any excitable and oscillatory stochastic system with a coherent state. The observed gain in coherence and synchronization in the cluster is achieved nearly instantaneously. This suggests the interesting possibility that Schwan's cells use noise to produce coherent signals (in the mm-wave range). The global output signal in that case should be markedly different from the output signal of an individual element. This behavior could potentially be investigated experimentally.
