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.
在对大鼠情感积极(下丘脑外侧区)和消极(被盖背内侧区)结构进行刺激的条件下,研究了情绪对前额叶皮质(左右半球)单位活动的影响。刺激导致左右半球的单位活动均发生变化。前额叶皮质左右区域的神经元反应表现出不对称性:在情感积极刺激期间,左侧皮质的单位活动更强烈,而在消极刺激期间,右侧皮质的神经元更活跃。在消极情绪刺激的情况下,对侧刺激时神经元反应的不对称性更大,在积极刺激时,左右定位同样有效。
