study of the evolutionary process of the vertebrate telencephalon

我们研究了七鳃鳗、龟、鼠等几种脊椎动物的发育过程。通过比较分析，我们确定在脊椎动物的共同祖先中已经建立了制造大脑皮层的基本形态机制。另一方面，哺乳动物和爬行动物从端脑到丘脑的神经元投射是不同的，这表明在羊膜动物的谱系中，神经元回路形成的机制似乎发生了改变。

We studied the developmental process of several vertebrates including the lamprey, turtle, mouse and so on. Through the comparative analysis, we identified that the basic morphological mechanism to make pallium has been established in the common ancestor of vertebrates. On the other hand, the neuronal projection from telencephaon to thalamus is different between mammals and reptiles, suggesting that the mechanism for the neuronal circuit formation appear to be modified in the amniote lineage.
