人脑通过神经元突触之间相互连接形成一个复杂的网络系统,多数神经、精神疾病都与这一系统中的连接受损有关[1]。人脑的不同区域有其不同的功能,但功能的实现需要多个脑功能区相互作用、彼此协调,即大脑功能的执行依赖于多个脑区广泛的交互作用[2],因此需要从网络的角度研究人脑的功能。图论是描述网络特征的重要工具,近年来影像等技术的发展使得基于图论的复杂脑网络研究成为可能[3]。
The human brain interconnects neuronal synapses to form a complex network system, and most neurological and psychiatric disorders are implicated in impaired connectivity in this system [1]. Different regions of the human brain have different functions, but the realization of the function requires the interaction and coordination of multiple brain regions, that is, the execution of the brain functions depends on a wide range of interactions in multiple brain regions [2] Study the function of human brain. Graph theory is an important tool to describe network features. In recent years, the development of imaging technologies has made it possible to study complex brain networks based on graph theory [3].
