Electroencephalographic and vegetative correlates of the mental reproduction of emotional states.

The present investigation is devoted to an analysis of the changes in the bioelectrical and vegetative indices during the mental reproduction of emotional states by man. An analysis of the data of the mapping of intracortical interactions as a function of the time course of the changes in the R-R interval was carried out. Two stages in the mental reproduction of emotions were identified which are characterized by the presence of different centers of integration, in the frontal and temporal divisions of the cerebral cortex. It was demonstrated that in the presence of maximal emotional tension the center of integration shifts from the frontal regions to the temporal region of the left hemisphere.
