How yawning switches the default-mode network to the attentional network by activating the cerebrospinal fluid flow

Olivier Walusinski
2013 Clinical anatomy (New York, N.Y. Print)  
In this article, we propose a new theory involving the brain network that is functional during the resting state, that is, the default mode network.  ...  When this network is active, yawning manifests a process of switching to the attentional system through its capacity to increase circulation of cerebrospinal fluid (CSF), thereby increasing clearance of  ...  ACKNOWLEDGMENTS The authors thank the revievers for their pertinent suggestions and Maria Rosaria Melis for her thoughtful comments in the preparation of this manuscript (Department of Biomedical Sciences  ...

2013 Frontiers in Human Neuroscience  
Nowadays, a network perspective is considered to be essential to the understanding of the development, progression, and management of epilepsy.  ...  Although the reasons for surgical failure are not fully understood, electrophysiological and imaging data suggest that anomalies extending beyond the temporal lobe may have negative impact on outcome.  ...  The default mode network includes a collection of medial frontal, midline parietal, and lateral parietal regions that show increased activation in the absence of a specific tasks, and whose function may  ...
