The cerebellar cortex of adult hens contains a dense plexus of thin varicose nerve fibers which display a formaldehyde-induced green fluorescence. This plexus is not distributed at random in the cortical layers. Within the granular layer the plexus forms a netlike pattern. The fiber branches, which have numerous varicosities, are predominantly oriented in the traverse plane of the folium. In the molecular layer the fluorescent plexus shows some variations in the convex, flat and concave portions of the folia. Many of the fluorescent branches are oriented parallel to the course of the folium. They arise from a T-division of radially oriented axons resembling parallel fibers in Golgi sections. The meshes of the fluorescent plexus in the granular layer measure 10-60 mu. In the molecular layer (top of the folia) there are about 30 fluorescent fibers per 100 mu2. The fluorescent fibers originate from the locus coeruleus and form a rostral and a caudal bundle in the cerebellar peduncle. The mode of distribution of the fluorescent fibers in the cortical layers seems to depend on the organization of the innervated tissue. Light microscopy suggests that the aminergic fibers innervate more than one class of cerebellar neurons.
成年母鸡的小脑皮质含有密集的细静脉曲张神经纤维丛，呈现甲醛诱导的绿色荧光。该神经纤维丛并非随机分布于皮质层。在颗粒层内，神经纤维丛形成网状图案。具有大量静脉曲张的纤维分支主要沿小叶的横平面排列。在分子层中，荧光神经纤维丛在小叶的凸面、平面和凹面部分呈现出一些变化。许多荧光分支与小叶的走向平行。它们源自呈放射状排列的轴突的T形分支，类似于高尔基切片中的平行纤维。颗粒层中荧光神经纤维丛的网眼大小为10 - 60微米。在分子层（小叶顶部），每100平方微米约有30条荧光纤维。荧光纤维起源于蓝斑，在小脑脚中形成一个嘴侧束和一个尾侧束。荧光纤维在皮质层中的分布方式似乎取决于所支配组织的组织结构。光学显微镜显示，胺能纤维支配不止一类小脑神经元。
