[Neurocyte reaction of the kinesthetic analyzer of rats to the action of vibration].

By neurohistological, morphometric and electron-microscopic methods the effect of vibration of 80 Hz applied at an acceleration of 8 m/sec2 on the nerve cell and conduction components of the kinesthetic analyzer was investigated. After a single exposure to vibration nerve cells of the sensorimotor cortex showed some changes. Exposure to vibration for as long as a week caused reactive changes in every structure of the kinesthetic analyzer investigated. After 1-month exposure the changes were more disseminated and became destructive, after 2-month exposure the process developed at a slower rate, and after 3-month exposure it remained at the same level. However, after 3-month exposure the morphological equivalent of compensatory-adaptive reactions was seen.
