The Influence of Coherent Monochromatic and Non-monochromatic Electromagnetic Radiation on the Human Brain Rhythms

This work is aimed at studying the effect of non- monochromatic electromagnetic radiation in the visible range on the rhythms of the human brain and a comparison of the results obtained with that known in the literature about the influence of coherent monochromatic radiation on the brain rhythms. At the present time, research results indicate that effect of monochromatic and non-monochromatic electromagnetic radiation on biological objects is identical. It can be also stated that comprehensive investigations concerning the influence of electromagnetic radiation of the visible range on human brain rhythms have not been carried out yet. We carried out experiments on electromagnetic radiation effects of the visible range on brain rhythms. The hand skin of visually impaired peoples was irradiated by visual light of different wavelength and the effects were registered by using complex KSD. Our experiments have shown that the rhythms of the brain vary depending on the wavelength of the electromagnetic radiation. The experiments have also shown that initially low activity of alpha rhythm level in the visually impaired people strongly depends on the wavelength of electromagnetic radiation acting on the hand skin, despite the fact that the people's attention was constantly focused on their sensations. At the same time other researchers have found an increase in alpha rhythms in response to laser stimuli, which may be associated with cognitive processes: focusing on tasks and sensations, although vision, hearing and somatosensory processes suppress the alpha rhythms. The results obtained have not only theoretical, but also the great practical interest, since it may assist in an effective treatment of various diseases.
