Excitatory effect of electric stimulation of the ventro-caudal area of the lateral hypothalamus on the neurons of the rabbit optic cortex was seen mainly in the cells whose activity increased under the influence of acetylcholine applied microiontophoretically. Meanwhile atropine applied microiontophoretically decreased or completely blocked the hypothalamic excitatory effect as well as that of acetylcholine. Atropine did not change the depressing influence of the rostral region of the lateral hypothalamus on the neuronal cortical activity. It is concluded that the hypothalamo-cortical excitatory relationships are M-cholinergic in nature.
电刺激家兔下丘脑外侧腹尾区对视皮层神经元的兴奋作用，主要见于那些在微量离子电泳施加乙酰胆碱影响下活动增强的细胞。同时，微量离子电泳施加阿托品可降低或完全阻断下丘脑的兴奋作用以及乙酰胆碱的兴奋作用。阿托品并不改变下丘脑外侧头端区域对皮层神经元活动的抑制作用。由此得出结论，下丘脑 - 皮层的兴奋关系本质上是M - 胆碱能的。
