Abstract

Following chronic decortication, free postsynaptic sites were found in the lateral geniculate nucleus of adult cat. Quantitative electron-microscopic analysis of the free postsynaptic sites revealed that they were not identical with the original, vacant postsynaptic sites, but were newly assembled formations. The ability of both relay cells and local interneurons of the adult lateral geniculate nucleus to assemble and/or maintain postsynaptic sites indicates that these nerve cells may be involved in the formation of new synapses.

摘要

在进行慢性去皮质手术后，在成年猫的外侧膝状核中发现了游离的突触后位点。对这些游离突触后位点进行的定量电子显微镜分析表明，它们与原来的空缺突触后位点不同，而是新组装形成的结构。成年外侧膝状核的中继细胞和局部中间神经元组装和/或维持突触后位点的能力表明，这些神经细胞可能参与了新突触的形成。
