Disrupted directed connectivity along the cingulate cortex determines vigilance after sleep deprivation

Giovanni Piantoni, Bing Leung P. Cheung, Barry D. Van Veen, Nico Romeijn, Brady A. Riedner, Giulio Tononi, Ysbrand D. Van Der Werf, Eus J.W. Van Someren
2013 NeuroImage  
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.  ...

Losing the struggle to stay awake: Divergent thalamic and cortical activity during microsleeps

Govinda R. Poudel, Carrie R.H. Innes, Philip J. Bones, Richard Watts, Richard D. Jones
2012 Human Brain Mapping  
Visual rating of performance and eye-video revealed that 70% of the participants had frequent microsleeps. fMRI analysis revealed a transient decrease in thalamic, posterior cingulate, and occipital cortex  ...  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] .  ...
