Summary of core intrinsic functional networks.

Network	Hub Regions	Functional Roles
Salience network (SN)	Dorsal anterior cingulate cortex, anterior insula	Salience detection, attentional switching
Default mode network (DMN)	Medial prefrontal cortex, posterior cingulate cortex	Internally directed cognition
Central executive network (CEN)	Dorsolateral prefrontal cortex, posterior parietal cortex	Goal-directed cognition, cognitive control
Basal ganglia network	Striatum, cerebellum	Motivation, autonomic function, arousal
Limbic network	Amygdala, hippocampus, thalamus	Motivation, autonomic function, arousal
