[The convergent properties of the neocortical vestibular area in the cat].
In acute experiments on cats under nembutal-chloralose anaesthesia the evoked potentials and cellular reactions were studied of suprasylvian vestibular and auditory projection zones to stimulation of vestibular, acoustic and visual nerves and frontal paw. It has been shown that the suprasylvian vestibular zone represents the region of convergence of vestibular, auditory, somatic and visual afferentation. Properties of summary and cellular reactions of the vestibular zone and also the character of interaction of the evoked potentials of homo- and heteromodal origin testify to the absence of significant dominance of vestibular input to this area of the cerebral cortex in cats. Limitation of spreading of labyrinth activity in the cerebral cortex and the absence of dominance of homomodal input in the projection zone should, probably, be considered as typical property of the vestibular system presentation in the cortex, determining the disability of monomodal specific reaction in the sensory-perceptive sphere.
