COHERENT EEG-ANALYSIS OF TRACE PROCESSES IN ANIMAL HYPNOSIS IN RABBITS

Dynamics of structural changes of coherent relations between electrica l activity of sensorimotor and premotor corticala reas of both cerebra l hemispheres during and after <<animal hypnosis>> was studied by spec tral-correlative analysis in rabbits. it was shown that <<animal hypno sis>> had very long-lasting trace processes i.e., hypnotic structure o f coherent relations of electrical activity in the cerebral cortex was maintained during several days. During and after a hypnotic episode i nterhemispheric asymmetry of electrical activity arose being more expr essed in the delta-range in the left hemisphere. <<Centers of animal h ypnosis>> were able to sum not only the effects of repeated hypnotic e pisodes but also excitation induced by sound stimuli immediately after hypnotic period and in the following days. Focus of stable activity w ith dominant properties was formed in CNS during <<animal hypnosis>>.
