[The effect of vibration on the impulse activity of cortical neurons and their reaction to stimulation of the posterior hypothalamus and Deiters' vestibular nucleus].

The effect of vibration on spontaneous unit activity, oxygen consumption in cortical neurons and their responses to stimulation of posterior hypothalamus and vestibular Deiters' nucleus, were studied. Biphasic changes occurred in frequency of cortical unit activity and in the latter interrelationships with the level of oxygen consumption after 3-hour exposure to the vibration. The 15-day vibration enhanced the mean frequency of unit activity, facilitated the effect of subcortical neurons and eliminated bursts of discharges. The effect of long-term vibration upon cortical unit activity response to stimulation of subcortical structures was quite obvious.
