The salience network is a large scale network of the human brain that is involved in detecting and filtering salient stimuli, as well as in recruiting relevant functional networks. wikipedia

Together with its interconnected brain networks, the salience network contributes to a variety of complex functions, including communication, social behavior, and self-awareness through the integration of sensory, emotional, and cognitive information.
Within the framework of our network model, the disparate functions ascribed to the insula can be conceptualized by a few basic mechanisms: (1) bottom–up detection of salient events, (2) switching between other large-scale networks to facilitate access to attention and working memory resources when a salient event is detected, (3) interaction of the anterior and posterior insula to modulate autonomic reactivity to salient stimuli, and (4) strong functional coupling with the anterior cingulate cortex that facilitates rapid access to the motor system. pub
A rare brain stimulation study suggests that a brain circuit known as the “salience network” contributes to differences in our ability to overcome challenges and cope with stress. post
