Disrupted directed connectivity along the cingulate cortex determines vigilance after sleep deprivation
2013
NeuroImage
Preserved Fulltext
Effective connectivity along the cingulate cortex was dominant in the forward direction. ...
Sleep deprivation impairs this directed information flow, proportional to its deleterious effect on vigilance. Therefore, sleep may play a role in the maintenance of waking effective connectivity. ...
Fig. 3 . 3 Effective connectivity along the cingulate cortex is affected by eye closure and sleep deprivation, but only in the forward direction. ...

They also suggest that the occurrence of microsleeps during an active task is not a global deactivation process but involves localized activation of fronto-parietal cortex, which, despite a transient loss ...
In contrast, after sleep deprivation, disruption in thalamic and visual processing areas occurs during slowed responses [Chee and Tan, 2010; Chee et al., 2008] . ...
