The Salience Network

The Salience network is made up of the anterior cingulate cortex and the insula.  Together they coordinate to monitor the conditions in the body for homeostasis (insula) from temperature, to pH, to pain, to hormonal discomfort and notify the anterior cingulate cortex.  You may recall that the ACC handles conflict.  Well, those would be the conflicts.  Also keep in mind that information coming in through the senses, including auditory, visual, and tactile are part of the data integrated by the insula.

Once the salience network is activated it modulates the default mode network.  It kicks the brain out of daydreaming, mind wandering,  and other self-referential behavior and into ready for action mode.
