[Impact of vibration on impulse activity of neurons of ipsilateral medial vestibular nucleus of unilaterally delabyrinthined rats]

Background impulse activity of the neurons of ipsilateral medial vestibular nucleus of unilaterally delabyrinthined rats was studied on different days after operation as well as after 5-day vibration. It was found that in intact animals mean neuron discharge rate is 16.6+/-1.7 Hz. On day 2 after affection it falls to 14.7+/-0.9 Hz and returns to the baseline on day 7 after surgery (16.6+/-1.2 Hz). Vibration impact raises mean impulse frequency to 21.2+/-2.8 Hz. Characteristics and significance of the results obtained are discussed.
