The salience network, also referred to as the midcingulo-insular network or cingulo-opercular network in anatomical parcellation schemes, is a large scale network of the human brain that is primarily

…cortex with the pregenual anterior cingulate cortex (Brodmann area 33) and the anterior and posterior mid-cingulate cortices, and, second, a general salience network concerned with environmental monitoring, response selection, and skeletomotor body orientation that involves all of the insular cortex and the mid-cingulate…
The salience network is theorized to mediate switching between the default mode network and central executive network.
Interaction between the ventral (salience) and dorsal attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation.
