中缝正中核的功能研究进展

Recent advance in functions of median raphe nucleus

中缝正中核(MRN)是中缝核群的主要核团之一,细胞数量和类型众多,涉及的神经环路范围广泛,功能非常复杂。近年来的研究发现其可能参与情绪、记忆形成与提取、睡眠-觉醒以及成瘾等过程的调节。本文围绕近年来对中缝正中核的功能研究进展进行综述,以期为后续研究提供参考。

Median raphe nucleus(MRN)is one of the main nuclei of the raphe nucleus group.It has a large number and types of cells and involves a wide range of neural circuits,so its function is complicated.Numerous studies have found that it may be involved in emotion regulation,memory formation and retrieval,sleep-wake and addiction processes.This article summarized research progress of MRN function in recent years,in order to provide reference for future research.
