How yawning switches the default-mode network to the attentional network by activating the cerebrospinal fluid flow
2013
Clinical anatomy (New York, N.Y. Print)
Preserved Fulltext
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 ...
