[Respiratory system activity in laser irradiation of brain structures].

It has been shown that the low-level laser radiation with the wave-length in the red part of spectrum changes greatly the activity of the respiratory center under the direct influence on the rats' brain structure. The influence of light may have activating or inhibitory character; sometimes symmetry in the respiratory center activity is disturbed. The difference of the effects under the radiation of the sensomotor area of the cerebral cortex hemispheres and the area of the bulbar respiratory center has been found out. It is supposed that one of the reasons of the functional state of the respiratory center variations is the metabolism change in its structures.
