三叉神经中脑核的研究进展

Progress of the Studies on the Mesencephalic Trigeminal Nucleus

三叉神经中脑核是唯一的位于中枢内的初级感觉神经元 ,主要传递口面部本体感觉信息。由于其结构和分布的特殊性 ,使得人们对它的了解很不完全。近年来随着方法学的进步 ,有关三叉神经中脑核的研究逐渐增多起来。本文结合形态学和电生理学两个方面 ,综述了关于三叉神经中脑核的研究进展 ,以期为进一步阐明口面部本体感觉信息的产生和调控机制奠定基础。

The mesencephalic trigeminal nucleus (Vme) consists of a unique population of primary sensory cell somata located within the central nervous system which transmits proprioceptive sensory signals from orofacial region. Because of the specificity of configuration and distribution, the understanding of Vme is limited. Recently, with the development of methodology, the study on Vme is becoming one of the highlights in neuroscience. We reviewed the progress of morphological and electrophysiological studies in recent years, which will make contribution to the understanding of transmition and regulation mechanisms of orofacial region porprioceptive sensory information.
