Altered functional integration in the cerebral cortex during the sleep-deprived state
  Altered functional integration in the cerebral cortex is related to changes in cognitive performance
  Changes in functional integration and cognitive performance following a recovery nap
  Functional clustering of brain activity is robustly associated with conscious states
  Functional integration is linked to the amplitude of local and global signal fluctuations
  Relationships with sleepiness and physiological markers of sleep pressure
  Changes in subcortical connectivity
