A frightening memory can protect you, or make a safe place feel dangerous. This study finds that the brain can change how widely fear spreads without changing how strong the fear itself is. What if a fear memory could become broader or more specific without stress hormones being the thing that controls it? This study identifies a prefrontal circuit that separates memory specificity from memory strength.
