[Effects of lateralized electric stimulation of the brain on audiogenic convulsive attack in rats]

The influence of lateralized and bilateral electrical stimulations of the rat's brain on the course of audiogenic convulsive fit was analyzed. It was found, that after operative application of electrodes to the animal's skull the strength of fit and audiogenic seizure susceptibility decreased in all experimental groups. At the same time the second group, in which the left hemisphere was stimulated, essentially differed from other groups. The occasions of omission of some stages of fit were not so frequent, there, and only in this group after electrostimulation fits increased in the form of arising of new stages. This allows us to propose a special role of the left hemisphere of rats in forming a complete convulsive fit. The described observations resemble those of human asymmetry.
