Fragmentation and multithreading of experience in the default-mode network

F. Yazin, G. Majumdar, et al.

Using fMRI during movie watching and narrative listening, this study reveals three topographically distinct midline prefrontal regions that perform separate predictive operations: ventromedial PFC updates contextual predictions (States), anteromedial PFC handles social reference-frame shifts (Agents), and dorsomedial PFC predicts transitions across abstract state spaces (Actions). Prediction-error-driven updates aligned with belief changes and were integrated with visual streams in the Precuneus, generalizing across modalities.
