摘要 人脑是一个复杂的网络,不同的功能区域相互作用、相互协调。本文综述了静息态脑功能网络的小世界属性研究方法,首先介绍了基于图论的复杂网络模型的基本概念和特征度量,然后介绍了基于功能磁共振成像数据构建脑功能网络的方法,最后分析了构建的脑功能网络的小世界属性。 The human brain is a complex network of different functional areas which interact andcoordinate with each other. The paper reviews the research methods for the small world properties of resting stateof brain functional network. This paper introduces the basic concept and characteristics measurement of thecomplex network model based on graph theory,recommends a method of constructing brain functional networkbased on functional magnetic resonance imaging(fMRI) data. Finally,it analyzes the small-world properties ofthe brain functional network.
