【 摘 要 】

With the help of a highly sensitive laser device with the wavelength λ = 0.808 pm, which is optimal for deep penetration of the radiation into biological tissues, the effects associated with the appearance of uncontrolled human infrasonic vibrations of different frequencies were investigated. It was established that the observed fluctuations are associated with the vascular system which is characterized by its own respiratory movements, occurring synchronously with the movements of the respiratory muscles, the operation of the heart muscle, and the effect of compression ischemia. The effect of "enlightenment" of a tissue is observed with stopping of blood flow in vessels by applying a tourniquet on the wrist.
