From groupwise to individual brain functional networks parcellation and application

Numerous brain imaging studies revealed that human behavior and cognition, which included perception, attention, memory and personality, are complex processes. The neural correlates underlying these fundamental cognitive functions are not associated with a particular brain region, but closely related with our human brain functional networks. In recent years, the development of new brain connectivity technologies for mapping the whole brain functional networks advanced the knowledge of comprehensive neuronal circuits and systems. For instance, we can examine the architecture of these functional networks by a wide variety of graph theory tools. Previous studies suggested that brain networks were modular and hierarchically organized, and they consisted of blocks or subnetworks that were particularly densely connected, but not spatially depended.
