Large-scale brain networks are identified by their function and provide a coherent framework for understanding cognition by offering a neural model of how different cognitive functions emerge when different sets of brain regions join together as self-organized coalitions. The number and composition of the coalitions will vary with the algorithm and parameters used to identify them. In one model, there is only the default mode network and the task-positive network, but most current analyses show several networks, from a small handful to 17. The most common and stable networks are enumerated below. The regions participating in a functional network may be dynamically reconfigured.

大规模脑网络是通过其功能来进行识别的。通过研究大规模脑网络建立神经模型，对不同脑区组合所形成的自组织联合体如何实现不同的'''<font color="#ff8000">认知Cognition</font>'''功能进行解释，就能够为认知理解提供一个连贯的框架。识别算法和参数的不同会导致所识别出的上述联合体的数量和组成有所不同。（一个模型理论认为，符合上述条件的神经模型只包含'''<font color="#ff8000">默认模式网络Default mode network</font>'''和'''<font color="#ff8000">任务激活网络Task-positive network</font>'''，但目前大多数分析理论都包括从几个到17个不等的网络。）CY下面列举了最常见且稳定的网络。'''<font color="#32CD32"> （人脑）</font>'''可以动态地重新配置参与功能网络的脑区。

*The default mode network is active when an individual is awake and at rest. It preferentially activates when individuals focus on internally-oriented tasks such as daydreaming, envisioning the future, retrieving memories, and theory of mind. It is negatively correlated with brain systems that focus on external visual signals. It is the most widely researched network.

*默认模式网络在个人清醒和休息时处于活动状态。当个体专注于面向内部的任务时，比如做白日梦、展望未来、回忆和心理理论，它就会优先激活。它与专注于外部视觉信号的大脑系统负相关。它是研究最广泛的网络。
