[Influence of terahertz (submillimeter) laser radiation on neurons in vitro]

The development of new sources of coherent non-ionizing radiation in terahertz wave range put forward the basic problems of revealing the mechanism of its action on biological objects, especially, on the nervous system. At this point it is necessary to reveal the radiation effects on complex molecular systems such as nerve cells. It was the main objective of this study. In the previous study we were the first to demonstrate highly specific effects of some examined wavelengths on the structural-functional properties of the nerve cells. The radiation of a free-electron laser produced damage to neuron morphology dependent on the power and wavelength. Transparent blank protrusions of the membrane, disorders of the growth of processes, and fall of the membrane potential were observed. The model developed and the data obtained approach the understanding of the molecular mechanisms of the effect of the waves under study on cells. These waves can be probably used as a tool for further investigation of functioning of neurons and neural system and correction of some pathology.
