Granger causal influence predicts BOLD activity levels in the default mode network.

Human Brain Mapping 2011 Qing Jiao, Guangming Lu, Zhiqiang Zhang et al.

Although the brain areas in the default-mode network (DMN) act in a coordinated way during rest, the activity levels in the individual areas of the DMN are highly heterogeneous. The relation between the activity levels and the pattern of causal interaction among the DMN areas remains unknown. In the present fMRI study, seven nodes of the DMN were identified and their activity levels were...
