Summary

Story summary

A study by UAB and Ruhr-Universität Bochum identifies brain signals related to fear memory extinction, published in *Nature Human Behaviour*.
Researchers examined 49 epileptic patients with implanted electrodes, linking neutral images to unpleasant sounds.
Increased theta activity in the amygdala during extinction learning suggests a safety signal.
Extinction memories rely on context, influencing their retrieval likelihood.
Findings may enhance therapies for PTSD and anxiety disorders.
