中文摘要：

自闭症谱系障碍（Autism spectrum disorders，ASD）是一种常见的神经发育障碍，ASD在社交、语言、行为等方面的障碍与其异常的大脑功能连接存在密切关系。与正常发育者相比，ASD大脑既表现出远距离功能连接不足，也表现出局部功能连接过度增强。ASD这种异常的脑功能连接受到结构异常、扫描状态、个体发展、分析方法等多种因素的影响。未来的ASD脑机制研究中，要综合分析脑功能与结构，关注年龄发展变化，并将任务状态、被试取样、数据分析标准等因素纳入考察。

英文摘要：

Autism spectrum disorders （ASD） is a common neurodevelopmental disorder. These patients suffer from social, language, and behavioral disturbances, which are associated with abnormal functional connectivity of the brain. Compared with typically developing participants, autistic people show an abnormal brain pattern of cortical under-connectivity and local over-connectivity. This abnormal brain function connection is influenced by many factors, such as atypical brain structures, scanning state, individual development, and analysis methods. In order to better understand the potential mechanisms under autism brain connectivity, future research should examine both the brain structures and functions, and consider participants＇ age, task status and other factors.
