Large-scale brain networks (also known as intrinsic brain networks) are collections of widespread brain regions showing functional connectivity by statistical analysis of the fMRI BOLD signal or other recording methods such as EEG, PET and MEG. An emerging paradigm in neuroscience is that cognitive tasks are performed not by individual brain regions working in isolation but by networks consisting of several discrete brain regions that are said to be "functionally connected". Functional connectivity networks may be found using algorithms such as cluster analysis, spatial independent component analysis (ICA), seed based, and others. Synchronized brain regions may also be identified using long-range synchronization of the EEG, MEG, or other dynamic brain signals.

大规模脑网络Large-scale brain networks(也称为内在大脑网络intrinsic brain networks)是在对基于血氧水平依赖BOLD效应的功能性磁共振成像fMRI信号的统计分析或其他记录方法(如脑电图EEG、正电子发射断层扫描技术PET和脑磁图MEG)中，表现出功能连接的脑区的集合。根据神经科学中一个新出现的范式，认知任务不是由单个脑区独立执行的，而是由几个互不相连的脑区“功能连接”组成的网络执行的。功能连接网络可以通过数据聚类Cluster analysis、空间独立元素分析Spatial ICA、种子点方法seed-based等算法来发现。同步的脑区也可以用脑电图、脑磁图或其他动态脑信号的远程同步来识别。
