The characteristics of neuronal activity of the Zona Incerta were compared after stimulation of the amygdala and central grey substance in acute experiments with rats. It is shown that the central grey substance stimulation produced activation in 86% neurons; the amygdaloid stimulation--inhibition in 64%. The convergence of impulses from the amygdala and central grey substance was observed in 58 of 174 reactive neurons. 57% of cells showed antagonistic convergent effects. Functional interrelations in system amygdala--Zona Incerta--central grey substance and the role of the antagonistic influences descending from the amygdala and ascending from central grey substance on neurons of the Zone Incerta are discussed.
在对大鼠进行的急性实验中，比较了刺激杏仁核和中脑中央灰质后未定带神经元活动的特征。结果显示，刺激中脑中央灰质可使86%的神经元产生激活；刺激杏仁核则使64%的神经元受到抑制。在174个反应性神经元中，有58个观察到来自杏仁核和中脑中央灰质的冲动汇聚。57%的细胞表现出拮抗性汇聚效应。讨论了杏仁核-未定带-中脑中央灰质系统中的功能相互关系，以及杏仁核下行和中脑中央灰质上行的拮抗性影响对未定带神经元的作用。
