Neurulation is an important stage in the embryo development of vertebrate, during which the ectoderm thickens into epidermal neural plate and then forms neural folds and neural tube.
脊椎动物胚胎发育过程中，神经胚期是一个重要的发育时期。这个阶段胚胎外胚层增厚形成上皮型神经板，神经板两侧隆起形成神经褶，随后神经褶两侧向背中线合拢并愈合成神经管。

The results show that the single-layered neural tube fails to form and the neural crest cells remain at the lateral regions in the explants with NTDs. However, the patterning of the neural tube is not affected as indicated by the normal expression of the preneural genes.
结果显示神经管闭合缺陷的移植体不能形成单层化的神经管，并且神经晴细胞滞留在侧面区域不能向背侧中线迁移，而对神经前体标记基因的检测显示神经管的背腹图式形成并未受到影响。

neural tube：神经管
在胚胎第四周长约2.5mm时,随着神经沟的不断加深,两侧的神经板也向背侧正中线包卷、融合,并脱离覆盖它的外胚层,这样就形成了神经管(neural tube),中空的管道称中央管.
