Light and electron microscopic studies have been made on degenerative changes in the nervous tissue induced by experimental destruction of the median brain bulb at the 5th day of incubation, in parts of the tecto-thalamo-telencephalic visual system in 13-day chick embryos (in the visual tectum, round nucleus of the thalamus and ectostriatum of the telencephalon). It was shown that to this period tecto-thalamic connections are already formed in the visual system, whereas thalamo-telencephalic connections are, presumably, indirect ones.
对孵化第5天经实验破坏中脑延髓后，13日龄鸡胚的顶盖 - 丘脑 - 端脑视觉系统部分区域（视觉顶盖、丘脑圆形核和端脑外纹状体）神经组织的退行性变化进行了光镜和电镜研究。结果表明，到这个时期，视觉系统中顶盖 - 丘脑连接已经形成，而丘脑 - 端脑连接据推测是间接连接。
