Abstract
Development of human brain is the essential process in the prenatal period of human growth. The total surface of human brain area is 1820 cm 2 , and the average cortical thickness is 2.7 mm. We reviewed and referred to several articles in this field. Comparative studies of the primate's brain show that there are general architectural basis governing the brain growth and evolutionary development. In this study, it is discussed about the human brain development with highlighting on the main mechanisms in the embryonic stage and early postnatal life as well as the general architectural values in brain evolution from primates to now. It is suggested that neurodevelopment involves some genetic bases in the neural stem cells proliferation, cortical neurons migration, cerebral cortex folding, synaptogenesis, gliogenesis, and myelination of neural fibers.
人脑的发育是人在产前发育过程中必不可少的过程。人脑区总表面积为1820 cm 2，皮层平均厚度为2.7 mm。我们回顾并参考了这一领域的几篇文章。对灵长类动物大脑的比较研究表明，大脑的生长和进化有一个共同的结构基础。本研究主要讨论了人类大脑的发育，重点讨论了胚胎阶段和出生后早期生命的主要机制，以及从灵长类动物到现在大脑进化的一般结构价值。提示神经发育涉及神经干细胞增殖、皮层神经元迁移、大脑皮层折叠、突触发生、胶质形成和神经纤维髓鞘形成等遗传基础。
