In chronic experiments on 25 adult cats, after transection of the brain-stem at the level of oral margins of the anterior colliculus, the effect of high-frequency electrical stimulation of the posterior hypothalamus and basal-lateral portion of the amygdala was studied. While stimulation of the posterior hypothalamus resulted in diffuse activation, that of basal-lateral portion of the amygdala rather rarely evoked a relatively weak long-latency activation of the neocortex. Frequently, stimulation of the basal-lateral amygdala induced epileptiform activity in the neocortex. Bilateral lesion of the amygdaloid complex did not affect the activating influence of the posterior hypothalamus on neocortex. It is suggested that the posterior hypothalamus, independently of the mesencephalic reticular formation and amygdaloid complex, exerts an activating influence on the neocortex.
在对25只成年猫进行的慢性实验中，在中脑前丘口缘水平横断脑干后，研究了高频电刺激下丘脑后部和杏仁核基底外侧部的效果。刺激下丘脑后部会导致广泛激活，而刺激杏仁核基底外侧部则很少能诱发新皮层相对较弱的长潜伏期激活。通常，刺激杏仁核基底外侧会在新皮层诱发癫痫样活动。双侧杏仁复合体损伤并不影响下丘脑后部对新皮层的激活作用。提示下丘脑后部独立于中脑网状结构和杏仁复合体，对新皮层发挥激活作用。
