Salience network

[3][4] Together with its interconnected brain networks, the SN contributes to a variety of complex functions, including communication, social behavior, and self-awareness through the integration of sensory, emotional, and cognitive information.

[7] Evidence that the salience network mediates a switch between the DMN and CEN comes from Granger causality analysis and studies utilizing transcranial magnetic stimulation.

[3] It has also been hypothesized that the AI receives multimodal sensory input and the ACC and the associated dorsomedial prefrontal cortex sends motor output.

In schizophrenia, both structural and functional abnormalities have been observed, thought to reflect excessive salience being ascribed to internally generated stimuli.

The VAN is commonly defined as a right-hemisphere-dominant network involving the temporoparietal junction and the ventral frontal cortex that responds to unexpected salient stimuli.

The salience network is theorized to mediate switching between the default mode network and central executive network . [ 1 ] [ 2 ]
Dorsal and ventral attention systems
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. [ 8 ]
