摘要

中央外侧核是丘脑内与痛和针刺镇痛有关的重要核团。它接受大脑皮层运动区和脊髓等脑部的纤维。其与皮质体感区的投射仅有 Jones 和 Künzle 用放射自显影方法证明皮质体感Ⅰ区有纤维至中央外侧核。而我们曾采用 HRP 方法证明中央外侧核内皮质体感Ⅰ区下行纤维起源于第Ⅴ层的锥体细胞。但至目前

有关皮质体感Ⅰ区与中央外侧核内神经原间的突触联系

还未见有文献报导。为此

本文应用光镜与透射电镜溃变方法研究皮质体感Ⅰ区下行纤维与中央外侧核的超微结构联系。

Abstract

Consecutive electrolytic lesion was made in the somatosensory area I of the cats.Axonal and terminal degenerations in the central lateral nucleus were observed by mean of light and electron microscope.The result showed that the somatosensory area I projects to caudal part of the central lateral nucleus via internal capsule.The fibers from synapses with neurons of the central lateral nucleus.These synapses mainly belong to the axo-dendritic and asymmetrical synapses.
