Salience Network

Salience Network (Ventral Attention Network/Midcingulo) #

  • 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.) 600
  • Hypnosis decreases DMN-CEN connectivity.

  • 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.
