Salience network

The functional-network construct that recurs across the wiki’s predictive and anatomical accounts. Anchored on the anterior insula and ACC (with amygdala and hypothalamus), identified by Seeley et al. (2007) as an emotional “salience” network dissociable from an “executive-control” network (DLPFC + parietal). See craig-2009-anterior-insula, ad-craig.

Role in the two frameworks

• Craig (2009): cites the salience network as evidence for the AIC/ACC dyad and notes that the right AIC appears to switch between the central-executive and default-mode networks — a hub role consistent with the AIC as the apex of the global-emotional-moment.
• Seth (2013): locates interoceptive-inference within a salience network “anchored on the anterior insular and anterior cingulate cortices,” where interoceptive predictions are generated, compared, and updated (his Figure 2). So the same network is read as an ascending salience detector (Craig) and as a predictive comparator (Seth) — the two poles of feedforward-vs-predictive-interoception.

Note

The salience network is a widely cited construct that will recur in future ingests (anxiety, addiction, psychosis all implicate it); this page is intentionally concise and will grow as sources accumulate.
