神经突

Objective To observe the normal morphology of axons in brainstem.

邓平目的观察脑干组织中神经轴突的正常形态。

Results The expressions of PDGF-B were increased in proximal nerve segments and regenerating axons in both models.

结果：两类损伤模型中，损伤近端神经和再生轴突PDGF-B的表达均增强。

Most axons in adult nerve tissue are ensheathed by single or multiple folds of a sheath cell.

成年人神经组织的大多数轴突外面都包裹着一层或多层鞘细胞。

Aike Guo and colleagues showed that mushroom bodies and the dopaminergic system may have some functional cooperation and that the circuit from the dopamine system to MBs is crucial for choice behavior in Drosophila.

抉择可以分为两个阶段，在抉择建立期需要蘑菇体和多巴胺能系统的突触传递功能，而在抉择执行期就不需要此神经环路机制。

Two-chamber shared culture medium can promote NSCs to differentiate into oligodendrocytes.

共培养液培养促进神经干细胞向少突胶质细胞分化。

NGF and BDNF reduced differentiation of NSCs into astrocytes, andincreased into oligodendrocytes in co-culture and two-chamber sharedmedium assay.

NGF或BDNF在不同的共培养体系中，可以起到减少神经干细胞向星形胶质细胞分化，增加少突胶质细胞分化的作用，而对神经元的分化没有影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
