摘要
以猫丘脑后核群内脏大神经单位诱发放电为内脏痛指标,研究杏仁中央核在抑制内脏痛中的作用。杏仁中央核与丘脑后核间存在一条多突触神经通路。电刺激杏仁中央核对内脏痛放电的抑制作用,是经由该通路的竞争抑制及其某些体液性因素实现的。
The authors took the unit discharges of the neuron in the posterior groupof thalamic nuclei (PO) caused by stimulating splanchnic nerve as an indi-cator of visceral pain. The result indicated that stimulating central neucleus ofamygdaloid (CE) could inhibit the most neuron discharges in PO. A multi-synaptic pathway was found to exist from CE to PO. The inhibition effectobserved arose from the competitive action between the impulses of splanchnicafferents and those of CE.
