Abstract

The fine structure of labelled spinothalamic terminals in the central lateral nucleus has been studied in the rat following injection of wheat germ agglutinin-horseradish peroxidase into the spinal cord. Myelinated axons gave rise to the labelled terminals, which were large profiles which contained round vesicles, numerous mitochondria, and formed asymmetrical contacts with large dendrites or dendritic protrusions. These profiles are similar to those described in other somatosensory thalamic nuclei, and in many other nuclei of the thalamus.

摘要

在将麦胚凝集素-辣根过氧化物酶注入大鼠脊髓后,对中央外侧核中标记的脊髓丘脑束终末的精细结构进行了研究。有髓轴突产生了标记终末,这些终末形态较大,含有圆形囊泡和大量线粒体,并与大的树突或树突突起形成不对称接触。这些形态与在其他躯体感觉丘脑核以及丘脑的许多其他核中所描述的相似。
