title: The role of the specific and nonspecific afferent systems in the mechanism of changes in evoked cortical responses in the presence of vibration.
abstract: The interrelationship of the activity of specific and nonspecific afferent systems in the mechanism of changes in the electrical activity of the cortex under the influence of vibration was studied under chronic experimental conditions. The character of the postvibrational shifts in the vestibulo- and reticulocortical evoked responses in the presence of the isolated and combined disengagement of the specific (vestibular) and nonspecific afferent systems of the brain was investigated. It was established that vestibular afferentation plays a significant role in the mechanism of postvibrational shifts in the vestibulocortical evoked responses, whereas nonspecific, as well as proprioceptive, somatic, and visceral as well as other inputs play the dominant role for the reticulocortical system of integration.
