室管膜细胞的许多基底突起外周延伸到所检查的四种哺乳动物的下丘脑的每个细胞群和区域：小鼠、大鼠、兔子和猫。通过高尔基-考克斯浸渍和尼氏复染，室管膜细胞过程似乎具有多种形式，并且与下丘脑内的神经元和毛细血管具有复杂的结构关系。有人提出，下丘脑室管膜细胞及其过程充当第三脑室脑脊液与下丘脑内神经元和毛细血管之间的通讯系统。讨论了这样一个系统在腺垂体功能调节中可能发挥的作用。还注意到，在所有下丘脑细胞群中，一些神经元的树突延伸到室管膜层。漏斗核内的一种不寻常的细胞，类似于小胶质细胞的形式，似乎被采用的高尔基-考克斯技术选择性地浸渍。该细胞具有漏斗核的特征，除极少数例外，仅限于该细胞群。其中一些蜘蛛细胞位于室管膜层上，并且还具有延伸至室管膜心室表面的末端。
Numerous basal processes of ependymal cells extend peripherally into every cell group and area of the hypothalamus of the four species of mammals examined: mouse, rat, rabbit and cat. With Golgi‐Cox impregnation and Nissl counterstaining, ependymal cell processes appear to have a variety of forms and of intricate structural relationships with neurons and capillaries within the hypothalamus. It is proposed that hypothalamic ependymal cells and their processes function as a communication system between the cerebrospinal fluid of the third ventricle and neurons and capillaries within the hypothalamus. The role that such a system may play in the regulation of adenohypophysial function is discussed.It was also noted that in all hypothalamic cell groups, dendrites of some neurons extend to the ependymal layer.An unusual cell, resembling microglia forms, within the infundibular nucleus appears to be selectively impregnated by the Golgi‐Cox technique employed. The cell is characteristic of the infundibular nucleus and, with rare exceptions, is confined to that cell group. Some of these spider‐cells lie on the ependymal layer and also have endfeet extending to the ventricular surface of the ependyma.
