UCLA Study Reveals Neurons Key to Decision-Making Under Uncertainty

10/11/2025

Summary

Story summary

Researchers at the University of California, Los Angeles identified neurons in the orbitofrontal cortex that activate when outcomes are uncertain.
Experiments with rats show these neurons contribute to decision-making and learning flexibility.
Inactivating the orbitofrontal cortex impaired rats' ability to adapt strategies under uncertainty.
Because humans have similar neurons, findings could inform treatments for anxiety and substance use disorders.
The study emphasizes that uncertainty is essential for learning and adaptation.
