Frontoparietal network relative shift

Frontoparietal network relative shift has no effect on fluid cognition in humans.

“Within-person coupling between the frontoparietal shift and fluid cognition was not detected.”

elapsed follow-up is associated with frontoparietal network relative shift in humans (5–8% per 5 years).

“the frontoparietal network shifted positively relative to the other nine networks in all four states, by 5-8% per 5 years.”
