If a person is not able to show stress in dangerous situations and lacks fear, there might be issues with an area of their brain known as the amygdala.
The amygdala is an almond-shaped structure which can be found in the medial temporal lobe of the brain, right in front of the hippocampus. It is a region of the brain which primarily deals with regulating our emotional processes like fear response but is also responsible for other strong emotions like aggression and pleasure. In case the amygdala gets damaged, it impairs the emotional memories of the person and also results in poor decision making.
