Switching on generalized fear. (https://pubmed.ncbi.nlm.nih.gov/38484060/)

These scientists wanted to understand how stress can make us feel scared even in situations that are not really dangerous. They found that when we are stressed, our brain switches the type of chemicals it uses to send messages. This change in chemicals can make us feel more fearful than we normally would. The scientists did experiments to see how this switch happens in the brain and how it affects our feelings of fear.
