Decode the phenomenon of dead people with fear

In nature, fear is a primitive instinct to help protect animals from predators. However, for humans, this emotion can be much more complicated.

In humans, fear can trigger a "fight or run" response , increase the heart rate, and sharpen the senses and increase energy to cope with the threat of survival.

Sometimes, the threat is so intense that it can cause "frozen" or "deadly" reactions . This phenomenon can be interpreted as when the brain is overwhelmed or a way to remain immobile to hide the enemy during evolution.

The feeling of fear is sometimes so intense that it can cause a "freeze" or "deadly" reaction.

Currently, neurologists have discovered exactly how the brain connects its survival system to the spine, causing the body to "die" in the face of danger.

As we all know, memories are acquired and stored in a small structure in the brain, called the amygdala . Any disturbing event will activate nerve cells in the lateral area and then the center of the amygdala. These signals are then transmitted internally, before connecting to nerve cells in the brain stem, the center is responsible for the fear response.

The researchers believe that the gray matter of the midbrain (PAG) can trigger reactions like "freezing", increase heart rate and blood pressure as well as the desire to fight or flee. Research by Bristol University (USA) has discovered a pathway of brain activity from the PAG region leading to the tower of cerebellar movement.

Tests have shown that the cerebellar region of the cerebellum is associated with the onset of deadly behavior when someone confronts danger. This discovery is expected to help develop effective treatments for emotional disorders, such as anxiety, panic or phobia.
