-
Basically manages the shifting between the Default Mode Network and the Executive Network. Consists of the Anterior Cingulate Cortex and Insula.
- Also related is the AKA dorsal attention network. Consists of the intraparietal sulcus and the frontal eye fields.)

Dissociable intrinsic connectivity networks for salience processing and executive control (Seeley et al. 2007) a landmark paper. >6k citations on semantic
- We identified a “salience network,” anchored by dorsal anterior cingulate (dACC) and orbital frontoinsular cortices with robust connectivity to subcortical and limbic structures, and an “executive-control network” that links dorsolateral frontal and parietal neocortices.
- What I know for sure is that the default mode network and more broadly a task-negative fMRI was already conceptualized for some years.
- Prior to this study, these 2 networks were less distinct
- They also coined the term “intrinsic connectivity network” here, I think.
