Chapter 6 endnote 21, from How Emotions are Made: The Secret Life of the Brain by Lisa Feldman Barrett.
Some context is:

These major hubs help to synchronize so much of your brain’s information flow that they might even be a prerequisite for consciousness.

A recent neuroimaging study using MEG (magnetoencephalography) showed that the default mode network, which is part of the interoceptive network, had the highest cross-network interaction when compared to other networks. (The other part of the interoceptive network, the salience network, was not studied.) The nodes of the default mode network are often considered to be the cortical core for dynamic integration across intrinsic networks.[1][2][3][4] Interestingly, regions of the default mode network contains traces of neural information from other networks, providing further evidence of its importance for integrating and synchronizing information flow across networks.[5]
