The posterior cingulate cortex (PCC) is a region at the back of the cingulate cortex, heavily connected to the Default Mode Network. It is involved in self-reflection, autobiographical memory, and the sense of being an observer of one's own experience.
Key Functions
- •Self-referential processing — "me" vs "not me"
- •DMN hub — active during mind-wandering, less active during focused attention
- •Witness position — PCC modulation can support the sense of "outsideness" — observing thoughts rather than being absorbed by them
- •Spatial orientation — contributes to the sense of where "I" am in relation to the world
In ONDA Life
Part 16 (I Witness) engages the PCC as a key element for maintaining a position of "outsideness" relative to one's own experience — the foundation of metacognitive monitoring and the witness stance.
