大脑边缘系统是中枢神经系统的重要组成部分,其解剖、生理都较复杂,近20多年来人们对它进行了较多的研究。早在1878年,法国外科医生Broca首先提出了“大边缘叶”这一名称。现在所谓的“边缘系统”便是由这一名称发展而来的。当时Broca所谓的边缘叶包括扣带回、海马回、胼胝体下回以及海马结构和齿状回。因这几部分结构都在大脑内侧面,呈环形包绕在大脑与间脑交接处的边缘,所以称为“边缘叶”,现在一般把边缘叶及其有关的皮质和皮质下结构,总称为“边缘系统”。
The limbic system is an important part of the central nervous system. Its anatomy and physiology are more complicated. More studies have been done on it in the past 20 years. As early as 1878, the French surgeon Broca first proposed the name “big margin leaf.” The so-called “fringe system” was developed from this name. At that time, Broca’s so-called marginal lobes included cingulate gyrus, hippocampus, inferior callosum and hippocampal formation and dentate gyrus. Because these parts of the structure are in the inner side of the brain, the ring is wrapped around the junction of the brain and the brain of the edge, so called “edge of the leaf,” now generally the edge of the leaf and its related cortical and subcortical structures, collectively “Edge System.”
