本文是作者发表的有关神经系统胚胎学的多篇论文的总结和讨论。脑分为原脑和后脑两部分只与神经板阶段有关。当神经板形成后，3个连续的增殖强化波以吻尾顺序通过，分别产生原神经节、神经节和迁移区的横带，即核原基。这些带后来被4个纵向带交叉。这样就形成了一个移民区网络。从每一个区域发生一次或多次连续的迁移，形成连续的迁移层。这些层最终被分成核。这些过程在脊椎动物系列中是极其一致的。迁移区域的4个纵向柱大致对应于生理学定义的His和Herrick的4个柱。最后，根据这些结果，试图确定5个经典脑区之间的界限。
The paper is a summary and discussion of a number of papers, published by the authors, on the embryology of the nervous system. The subdivision of the brain into an archencephalic and a deuteroencephalic part has relevance only to neural plate stages. When the neural plate has been formed, 3 successive waves of proliferation intensification pass in a rostro-caudal sequence, giving rise to proneuromeres, neuromeres and transverse bands of migration areas, i.e. nuclear anlages respectively. The bands are later crossed by 4 longitudinal bands. In this way a network of migration areas is formed. From each area one or more successive migrations take place, forming successive migration layers. The layers are finally divided into nuclei. These processes are astonishingly uniform in the vertebrate series. The 4 longitudinal columns of migration areas roughly correspond to the 4 columns of His and Herrick, defined physiologically. Fianlly an attempt was made to define the limits between the 5 classical brain parts on the basis of these results.
