中文摘要：
新皮质由神经上皮经过增殖、分化和神经细胞的迁移后逐步发育而来，新增殖的有丝分裂后神经元沿着放射状胶质细胞按照由内向外的迁移原则在皮质板定居下来。Cajal—Retzius细胞在新皮质发育及片层化过程中起着关键作用，Cajal—Retzius细胞分泌的reelin是迁移中神经元的终止信号和化学趋向信号，reelin的这些功能使得从大脑皮质的细胞构筑和纤维构筑得以形成。
英文摘要：
Neocortices develop through the neuroepithelial proliferation, neuronal differentiation and neuronal migration. The new proliferous postmitotic neurons migrate along radial glia and settle in cortical plate according to ＂inside-out＂ pattern. Cajal-Retzius cells play an important role in the development and lamination of neocortex. Reelin secreted by Cajal-Retzius cells acts as stopping signal and chemoattractant to the migrating neurons. The functions of reelin make the cellular and fibrous lamination of neocortex to become possible.
