在Nissl和Golgi染色的脑切片中研究了Wulst的细胞组织，以识别视觉感受神经元。根据其索马大小、树突形态和棘分布密度，将高尔基体浸渍神经元分为四种类型。I型神经元是Wulst中最大的细胞，具有长而直的树突和许多棘。II型神经元是具有长而直的树突的中等大小的细胞。这些树突有许多刺。III型神经元是具有无棘树突的中型或小型细胞。IV型神经元是Wulst中最小的细胞，具有短树突和稀疏的棘。通过Fink-Heimer方法确定丘脑前背外侧核外侧部（DLL）到Wulst的投影。DLL病变后，退化的终端被认为是在背外侧部分的第二，第三和第四型神经元分布的intercalatus hyperstriatum accessorium。DLL轴突的突触后元件通过电子显微镜连续切片的重建来鉴定。大部分突触后成分为II型和IV型神经元的树突棘，少数为III型神经元的树突轴。
The cellular organization of the Wulst was studied in Nissl‐ and Golgi‐stained brain sections in order to identify the visual receptive neurons. Golgi‐impregnated neurons were divided into four types according to their soma size, dendritic configuration, and density of spine distribution. Type I neurons, the largest cells in the Wulst, have long, straight dendrites with many spines. Type II neurons are medium‐sized cells with long, straight dendrites. These dendrites have numerous spines. Type III neurons are medium‐sized or small cells with spine‐free dendrites. Type IV neurons, the smallest cells in the Wulst, have short dendrites with sparse spines. The projections of the nucleus dorsolateralis anterior thalami pars lateralis (DLL) to the Wulst were determined by the Fink‐Heimer method. After lesions of the DLL, degenerating terminals are seen in a dorsolateral portion of the nucleus intercalatus hyperstriatum accessorium where the types II, III, and IV neurons are distributed. Postsynaptic elements to the DLL axons were identified by reconstruction of electron microscopic serial sections. Most of the postsynaptic elements were dendritic spines of the type II and IV neurons and a few were dendritic shafts of the type III neurons.
