- [[Default Mode Network (DMN)]] - Active during rest, mind-wandering, self-referential thought - Key regions: medial [[Prefrontal Cortex]], posterior cingulate cortex, angular gyrus - [[Frontoparietal Control Network (FPCN)]] - Supports cognitive control, flexible [[goal-directed behavior]] - Interacts dynamically with [[Default Mode Network (DMN)|DMN]] and attentional networks depending on task demands - Key regions: dorsolateral [[Prefrontal Cortex]], inferior parietal lobule - [[Salience Network]] - Detects behaviorally relevant stimuli, facilitates switching between [[Default Mode Network (DMN)|DMN]] and [[Frontoparietal Control Network (FPCN)|FPCN]] - Key regions: anterior insula, dorsal [[anterior cingulate cortex]] - [[Dorsal Attention Network]] - Supports top-down, voluntary [[Attention]] toward external stimuli - Key regions: frontal eye fields, intraparietal sulcus - [[Ventral Attention Network (VAN)]] - Supports bottom-up, stimulus-driven [[Attention]], especially to salient or unexpected stimuli - Key regions: [[Temporoparietal Junction (TPJ)]], ventral frontal cortex
