[The neurons of the right and left prefrontal areas of the rat cerebral cortex and the stimulation of emotiogenic zones].
The effect of emotions on unit activity of the prefrontal cortex (right and left hemispheres) was studied in rats under conditions of stimulation of emotionally positive (lateral hypothalamic area) and negative (dorsomedial tegmentum) structures. The stimulation produced changes in unit activity of both the right and left hemispheres. Asymmetry was revealed in neuronal responses of the right and left areas of the prefrontal cortex: during emotionally positive stimulation the unit activity in the left cortex was more intensive, and the neurons of the right cortex were more active during the negative stimulation. In case of the negative emotional stimulation the greater asymmetry in neuronal responses was observed at contralateral stimulation, at the positive stimulation both the left and right localizations were equally effective.
