The cholinergic innervation of the superficial layers of the ferret's superior colliculus was investigated with a combination of electron microscopy and choline acetyltransferase immunohistochemistry. Cholinergic boutons in the superficial layers of the superior colliculus possess spherical vesicles and make predominantly asymmetrical synapses onto the profiles of small dendrites, as do the terminals of cortical and retinal axons. In most areas of the brain studied so far, cholinergic terminals tend to form synapses of the symmetrical variety.
结合电子显微镜和胆碱乙酰转移酶免疫组织化学技术，对雪貂上丘表层的胆碱能神经支配进行了研究。上丘表层的胆碱能终扣含有球形囊泡，主要与小的树突形成不对称突触，皮质和视网膜轴突的终末也是如此。在目前为止所研究的大脑大多数区域中，胆碱能终末倾向于形成对称型突触。
