对硬骨鱼端脑大脑皮层的血管系统进行分析，可以了解位于室管膜附着部外侧的相当深的外沟。这条沟的深度是令人信服的证据，证明了在所有鳍鱼的端脑发育过程中，苍白球[每个半球的壁)都是简单的外翻过程，这在硬骨鱼中并不复杂，因为掌上细胞群的二次迁移。已知一些端脑细胞结构相对简单的鳍鱼存在简单的外翻过程，但在硬骨鱼中，基于嗅束投射的模式一直存在争议。在此，基于对脑沟解剖学和组织化学数据的重新检查，提出了一种关于横鳍鱼之间以及与其他颅骨辐射相比较的、相互矛盾的假说的解决方案。(C)2000年，爱思唯尔科学爱尔兰有限公司出版。
Analysis of vasculature in the telencephalic pallium of a teleost allows the considerable depth of the sulcus externus, which lies at the lateral extent of the ependymal attachment, to be appreciated. The depth of this sulcus is compelling evidence for a simple eversion process tan outfolding of the pallia[ wall of each hemisphere) during telencephalic development in all ray-finned fishes that is not complicated in teleosts by secondary migration of pallial cell groups. A simple eversion process is known to occur in some ray-finned fishes with relatively simple telencephalic cytoarchitecture but has been disputed in teleosts based on the pattern of olfactory tract projections. A resolution to the conflicting hypotheses of pallial relationships across ray-finned fishes and in comparison with other craniate radiations is presented here, based on a re-examination of hodological and histochemical data mandated by this sulcal anatomy.
