[The role of specific and nonspecific afferent systems in the mechanism of the changes in cortical evoked responses during vibration].

The correlation in activity of specific and unspecific afferent systems was measured in mechanisms changing electrical activity of the cortex during vibration. The character of postvibration shifts of vestibulo-, reticulo-cortical EPs was studied by means of isolated and combined exclusion of specific (vestibular) and unspecific afferent systems of the brain. The vestibular afferents seem to play a significant role in the mechanisms of postvibration shifts of vestibulo-cortical EPs. Impulses originating from the unspecific afferent systems, as well as proprioceptive, somatic and visceral afferents play similar role for the reticulo-cortical system.
