Modulatory Interactions between the Default Mode Network and Task Positive Networks in Resting-State
Communication between different brain systems is essential for complex functions. Using resting-state fMRI and a technique called physiophysiological interaction, the authors found that the salience network may modulate the relationship between the default mode network and executive networks. The basal ganglia and thalamus positively interacted with the salience and dorsal attention networks, while negatively interacting with the salience network and default mode network. These results reveal complex, modulatory interactions among brain networks during rest.
