Leu-enkephalin-like immunoreactive (ENK-I) elements appearing in the superficial layers of the rat superior colliculus (SC) after eye-enucleation were examined by means of immunoelectronmicroscopy. ENK-I somata were of a single type and formed symmetric and asymmetric synapses with non-immunoreactive axon terminals. Some degenerating retinal terminals made synaptic contacts only with small ENK-I dendrites, suggesting that deafferentation-induced ENK-I neurons in the rat SC receive retinal input onto the distal portions of their dendrites.
通过免疫电子显微镜检查摘除眼球后大鼠上丘（SC）表层出现的亮脑啡肽样免疫反应性（ENK-I）成分。ENK-I胞体为单一类型，与非免疫反应性轴突终末形成对称和不对称突触。一些退化的视网膜终末仅与小的ENK-I树突形成突触联系，这表明去传入诱导的大鼠SC中的ENK-I神经元在其树突远端接受视网膜输入。
