To obtain the characteristics of the main changes in oxidative metabolism in the neurons of the nucleus vestibularis anterior (NVA) under the influence of low frequency vibration in rat brain the activities of some dehydrogenases (NADN-DH, NADPH-DH, succinate-DH, malate-DH, beta-oxybutyrate-DH, alpha-glycerolphosphate-DH, lactate-DH, glutamate-DH and 6-phosphogluconate-DH) were measured using histochemical methods. The sizes of subpopulations of neurons differing in enzyme activities were estimated.
