Abstract:

Relative investigation of electrical activity of cortex and basal sections of the brain revealed certain additional characteristics in the nature of basal electrogram in comparison with the previously described ones. Vestibular irritation causes considerably greater changes in bioelectric activity of the brain, than do other afferent irritations. Electric response to irritation of the vestibular apparatus can be picked-up from all areas of cortex cerebri and in a majority of cases appears to be two-sided symmetrical. Responsive reaction to vestibular irritation in basal areas is expressed much brighter, more intensive and longer lasting, than in the cortex cerebri. Duration and multiphaseness of changes in electrical activity of the brain during vestibular irritation, apparently, are connected with the involvement into responsive reaction of a series of mechanisms, including the vegetative-vascular. A very important role is played in this case by the emotional factor. The obtained data, indicating considerable functional displacements in electrical activity of basal sections of the brain under the effect of vestibular irritation in norm, give bases to assume that illnesses of the central nervous system the changed nature of its reactivity may be easier to detect with the aid of the mentioned afferent irritation.
