[A coherent EEG analysis in the trace processes of "animal hypnosis" in rabbits].

Dynamics of structural changes of coherent relations between electrical activity of sensorimotor and premotor cortical areas of both cerebral hemispheres during and after "animal hypnosis" was studied by spectral-correlative analysis in rabbits. It was shown that "animal hypnosis" had very long-lasting trace processes, i.e., hypnotic structure of coherent relations of electrical activity in the cerebral cortex was maintained during several days. During and after a hypnotic episode interhemispheric asymmetry of electrical activity arose being more expressed in the delta-range in the left hemisphere. "Centers of animal hypnosis" were able to sum not only the effects of repeated hypnotic episodes but also excitation induced by sound stimuli immediately after hypnotic period and in the following days. Focus of stable activity with dominant properties was formed in CNS during "animal hypnosis".
