Classical electron microscopic morphological studies provide detailed ultrastructural information, which may lend insights into cellular functions. As a follow‐up to our morphological investigation of the adult zebrafish (Danio rerio) optic tectum, in this study, we have analyzed the ependymal structures lining the surfaces of the tectal ventricle: the torus, tegmental surface of the valvula cerebelli and the periventricular gray zone of the optic tectal cortex. We used toluidine blue stained plastic (semithin) sections for light microscopy and scanning electron microscopy. Our morphological findings of gated entrances and/or egresses indicate that, at least in the adult zebrafish brain, there may be a bidirectional direct flow communication between the ventricular cerebrospinal fluid and the parenchymal interstitial fluid.

斑马鱼成年斑马鱼视轴心室室管膜的区域差异，其结构涉及大脑流体动力学。

经典的电子显微镜形态学研究提供了详细的超微结构信息，可能有助于深入了解细胞功能。作为我们对成年斑马鱼（Danio rerio）视神经支架，在本研究中，我们分析了衬在脑室脑室表面的室管结构：环面，小脑被盖表面和视神经皮质的脑室周围灰色区域。我们将甲苯胺蓝染色的塑料（半胱氨酸）切片用于光学显微镜和扫描电子显微镜。我们通过门控入口和/或出口的形态学发现表明，至少在成年斑马鱼脑中，脑室脑脊液和实质间质液之间可能存在双向直接流动相通。
