Default Mode Network
- Three main subdivisions: ventromedial prefrontal, dorsomedial prefrontal, and posterior cingulate (Raichle 2015)
- Involved in self-referential thoughts (reflecting on one’s past, envisioning the future, emotion recognition) (Raichle 2015; Buckner and DiNicola, 2019)
- Can be divided into anterior component (more involved in self-reflection / emotion) and posterior component (more involved in episodic memory / perceptual processing) (Coutinho et al, 2016).
- Depressive / anxiety symptom scores have greater correlation with anterior components and negative correlation to posterior components (Coutinho et al, 2016; Mulders et al, 2015)
