FeaturedNeuroscience·March 25, 2026·8 min readHow the Amygdala Decides Between Freezing and FleeingResearchers have identified brain circuits in the central amygdala that decide whether an animal freezes or flees. The study shows that "unlearning" fear is actually a process of recalibrating these circuits, offering new insights into PTSD.Read More
