The ependyma in the region of the telencephalon of Salmo irideus is composed of a great number of various elements: uni- and bipolar tancytes, ependymal astrogliacytes, ciliated ependymal cells, intraependymal neurons and neuron-like cells exhibiting ventricular contact. There are regional differentiations in the ventricular wall which can be attributed to certain structurally defined nuclear areas. When comparing the various regions of the ventricular wall in the telencephalon of Salmo irideus with appropriate regions of amphibians and reptiles, some, at least partially, far-going morphological similarities can be found. The ependymal differntiations could, thus, be regarded as an additional morphological criterium concerning the question of the homologization of the telecephalic nuclear areas with those of other verebrates. The abundnat occurrence of tanycytes of the bipolar type in the telecephalon appeared surprising; they are discussed to act in a preponderantly resorptive manner, as it is, above all, hitherto known for hypothalamic regions of other vertebrates. The morphological and functional characteristics of the neuronlike structures exhibiting ventricular contact are as yet not clear.
单极和双极伸展细胞、室管膜星形胶质细胞、纤毛室管膜细胞、室管膜内神经元以及与脑室有接触的神经元样细胞。脑室壁存在区域分化，这可归因于某些结构明确的核区。将虹鳟鱼端脑脑室壁的不同区域与两栖动物和爬行动物的相应区域进行比较时，至少可以发现一些在形态上有很大相似之处。因此，室管膜分化可被视为关于端脑核区与其他脊椎动物核区同源性问题的一个额外形态学标准。在端脑中大量出现的双极型伸展细胞令人惊讶；据讨论，它们主要起吸收作用，就像迄今为止在其他脊椎动物下丘脑区域所知道的那样。与脑室有接触的神经元样结构的形态和功能特征尚不清楚。
