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.

因为大脑网络可以用不同的分辨率和不同的神经生物学特性来识别，所以没有适合所有情况的通用大脑网络图谱。在承认这个问题的同时，Uddin，Yeo，和 Spreng 在2019年提出，以下六个网络应该被定义为核心网络，基于来自多个研究的聚合证据，以促进研究人员之间的交流。
