# Brain circuit keeps tabs on what just happened to aid judgment of what’s happening now

**[MIT News](https://daily.dev/sources/mit)** · 6 min read · 0 upvotes · 0 comments

## Summary

MIT neuroscientists identified a brain circuit linking the pulvinar (lateral posterior thalamus in mice) with the anterior cingulate cortex that helps compare current sensory input against recent past experience. Using mice trained on a moving-dot direction task, two-photon imaging, and optogenetic perturbation, researchers found the pulvinar advises the ACC on how much sensory conditions have changed, allowing the ACC to decide whether to maintain or update a decision. The findings could inform research into autism, where predictive sensory filtering often differs from neurotypical patterns.
