Ng. Mikhailova et Mi. Zaichenko, NEURONS OF THE RIGHT AND LEFT PREFRONTAL CORTICAL AREAS AND STIMULATION OF THE EMOTIOGENIC ZONES, Zurnal vyssej nervnoj deatelnosti im. I.P. Pavlova, 48(3), 1998, pp. 431-437
The effect of emotions on unit activity of the prefrontal cortex (righ
t and left hemispheres) was studied in rats under conditions of stimul
ation 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 pre
frontal cortex: during emotionally positive stimulation the unit activ
ity in the left cortex was more intensive, and the neurons of the righ
t cortex were more active during the negative stimulation. In case of
the negative emotional stimulation the greater asymmetry in neuronal r
esponses was observed at contralateral stimulation, at the positive st
imulation both the left and right localizations were equally effective
.
