Scientists: anxiety helps humans in dangerous situations

Researchers from France have come to this conclusion during a series of experiments involving 24 volunteers. People were shown pictures with faces expressing different emotions.

Brightest volunteers took photos with people looking directly in the eye or expressing anger. In the brain of subjects at this point, scientists have detected a particular signal, indicating the transition of the nervous system in anxiety.
