Opposite Changes in Electrophysiological Reactions of the Human Brain in Adopting the Frequency of Light Flashes at Vestibular and Optokinetic Stimuli

摘要

Results of the investigation give bases to assume that the vestibular-oculomotorial system does not appear to be a simple reflectorial system, synonymously reacting to the stimulation of its various links. The nature of the interactions between these links is such that the stimulation of vestibular and optomotorial links affects in an opposite manner the level of excitability of the cortical structures connected with the analysis of light signals. The vestibular system has a depressing effect on the cortical structures of the visual analyzer, and the eyemotorial system exerts an opposite activating effect on the very same cortical structures.
