Summary

Story summary

A study in Nature Communications shows the brain builds a seamless experience using three predictive models—a State model for context, an Agent model for others, and an Action model for events—integrated in the precuneus.
Functional MRI reveals belief updates during naturalistic experiences, such as watching a film, aligning brain activity patterns.
The results suggest that individual differences in prediction integration shape subjective experience and advance understanding of cognition.
