使用Golgi-Cox方法与中性红或甲酚紫复染研究了大鼠视上核的细胞结构，以准确确定核的界限。在每个脑切片中都观察到少量染色的神经元，但它们在视上核中的分布不均匀。后视束细胞较多。研究的少数细胞（总共4个）是圆形的（直径约20 μ m）和多极的，并被解释为中间神经元。所研究的大多数染色细胞（60）具有椭圆形细胞体（在冠状切片中平均长直径为22.7 μ m），具有指向背侧和内侧的单个细轴突和穿过腹侧的1-3个较重的树突。主要细胞类型的胞体和树突均呈棘状突起，树突和轴突均具有一定程度的弯曲。较大细胞群（假定的神经分泌细胞）的解剖学与它们具有大量突触输入一致，并且长树突（高达205 μ m）的存在意味着在解释实验时必须谨慎，其中当活性材料放置在细胞体附近时监测细胞活性。
The cytoarchitecture of the rat supraoptic nucleus was studied using the Golgi-Cox method with a neutral red or Cresyl violet counterstain to allow the limits of the nucleus to be determined accurately. A small number of stained neurons were seen in each of the brains sectioned but they were unevenly distributed in the supraoptic nucleus. There were more cells posteriorly and close to the optic tract. A minority of cells studied (a total of 4) were round (diameter approximately 20 .mu.m) and multipolar and were interpreted as interneurons. The majority of stained cells studied (60) had oval cell bodies (mean long diameter 22.7 .mu.m in coronal sections) with a single fine axon directed dorsally and medially and 1-3 heavier dendrites passing ventrally. Both cell bodies and dendrites of the major cell type showed spines and both dendrites and axons had some varicosities. The anatomy of the larger cell group (the presumed neurosecretory cells) is consistent with their having a substantial synaptic input and the presence of long dendrites (up to 205 .mu.m) implies that caution is necessary in the interpretation of experiments where cell activity is monitored while active materials are placed near the cell bodies.
