It also allowed them to reliably see patterns: the seemingly inscrutable mass of connections in the cerebral cortex is highly organized, consisting of eight
distinct subnetworks that are relatively segregated.
Researchers have identified eight
distinct neural
subnetworks that together form the connectivity infrastructure of the mammalian cortex, the part of the brain involved in higher - order functions such as cognition, emotion and consciousness.
In this study, they examined anti-correlations of different
subnetworks within the DMN during rest using both seed - based and point process analyses, and discovered that: (1) the ventral branch of the DMN (vDMN) yielded significantly weaker anti-correlations than that associated with the dorsal branch of the DMN (dDMN); (2) vDMN anti-correlations introduced by GSR were
distinct from dDMN anti-correlations; (3) PCC / precuneus seeds employed by earlier studies mapped to different DMN
subnetworks, which may explain some of the inconsistency (in addition to preprocessing steps) in the reported DMN anti-correlations.
