Scientists fix brain circuit to reverse anxiety in mice

Scientists reversed anxiety in mice by fixing a specific brain circuit in the amygdala. This discovery offers a potential new target for treating anxiety disorders. The research identified a group of amygdala neurons whose imbalanced activity causes anxiety and social deficits. Restoring normal function in these neurons reversed these behaviors in mice. This finding suggests a general principle of emotional regulation in the brain and could lead to more targeted treatments for affective disorders.
