Parcellation-based tractographic modeling of the salience network through meta-analysis.

Background: The salience network (SN) is a transitory mediator between active and passive states of mind. Multiple cortical areas, including the opercular, insular, and cingulate cortices have been linked in this processing, though knowledge of network connectivity has been devoid of structural specificity.

Objective: The current study sought to create an anatomically specific connectivity model of the neural substrates involved in the salience network.

Parcellation-based anatomic modeling of the default mode network.

Background: The default mode network (DMN) is an important mediator of passive states of mind. Multiple cortical areas, such as the anterior cingulate cortex, posterior cingulate cortex, and lateral parietal lobe, have been linked in this processing, though knowledge of network connectivity had limited tractographic specificity.

Methods: Using resting-state fMRI studies related to the DMN, we generated an activation likelihood estimation (ALE).
