[The effect of whole-body vibration on the electrical activity and oxidative metabolism in different brain structures].

Chronic experiments on rabbits were performed to study the bioelectric activity, oxygen consumption and succinate dehydrogenase (DG) activity in different parts of the cortex and subcortex (mesencephalic reticular formation, lateral vestibular nucleus, thalamus posteroventrolateral nucleus), as well as the compound electric activity of the neck muscles, and rythm adoption. The phase character and different vibration sensitivity of the brain structures depending on the duration of vibration were revealed. At the initial phase, the following vibration effects were examined: reaction of activation on encephalogram, growing EMG and DG activity, increased oxygen consumption, and rythm adoption high frequency shifting. Prolonged vibration caused a vivid violation of the intracentral correlation between the cortex and subcortex. Correlation was also identified between electric activity and the brain structures' oxidation metabolism against the vibration dynamics levels.
