The secret of fear

Frightening is a kind of complex affection rooted at the bottom of the human heart, forming an instinct to stay away from danger, protecting yourself from being hurt. However, excessive fear reduces the quality of life.

In the brain stem section there is a lobe called Almond (amygdala).Although scientists soon knew that lobe almonds were the "terrifying center" in the brain, it was critical for the awful signal judgment, but it was unclear how it played in the process. judge this expression in humans.Recently, American scientists have also discovered this secret.

 

Conducting this study is Apollonia, a professor of American psycho-psychology and science.He has been watching for more than 20 years for a 38-year-old woman with a rare genetic disease that causes the lobe of the almonds to be damaged, so that regardless of the terrifying expression in others.

 

He showed the woman and other volunteers through the pinhole picture showing different emotions on the face, including a picture of a face showing terror, another image of a human face. show happiness.As a result, people with normal brains often look directly into their eyes, especially when faced with a face that shows fear.But the woman could not have an instinctive look at her eyes, but stared at the photo, finally judging that the face on the image did not show anything special.

 

Notably, if the scientist reminds the woman to pay more attention to the eyes of the people in the photos, she can also judge who is in a state of terror.But that ability only kept very short, constantly reminding her to pay attention to looking at the eyes of the people in the picture.

 

Researchers have come to the conclusion: The damaged almond lobe, although unable to direct the visual system to gather information, but its ability to process visual signals is still complete.In other words, besides analyzing the eyes' signals, the almonds also tell you first to pay attention to the eyes of others.

 

The bigger the white eyes appear, the easier it is to be intimidated

 

Scientists at the University of Wisconsin (USA) have studied a step further, found that on the face of people who are intimidated, white eyes (sclera) are exposed.

During the experiment, the researchers showed volunteers a series of photos showing affection and co-use of magnetic resonators to measure their brain activity.The results showed that the almond lobe of the volunteers only reacted to the eyes that were wide open because of fear, no reaction to pupils and black eyes.The level of reaction of the almond lobe is positively related to the large and small size of the eye white.Researchers speculate that the large variation of eye whites may be the only "terrifying" signal in the almond lobe that can absorb and react.

 

Find new ways to cure fear

 

Appropriate fear can help people avoid danger, protecting themselves from being hurt.But the fear for ordinary people who are not afraid will cause trouble, difficult for people to understand, even seriously affect the daily life and work.Therefore, finding the mechanism of brain recognition and elimination of panic can help liberate people who are surrounded by terror and obsession.

 

Neuroscience studies show that, assuming other parts of the brain are considering some of the events, not even realizing that they are in a state of attention to a terrible object, then lobe almonds still hour by hour, every minute warning that accidents are coming!For example, if the photo shows a facial expression that shows emotion on the screen at a very short time and is replaced by a photo of a face of indifference, the participant will say that only one set is seen. face accidentally.In the meantime, the almond lobe feels like it should increase its activity when the photo has feelings.When the photo with a face accidentally appeared, it immediately recovered as usual.

 

Almond lobes have a key effect in the process of recognizing and eliminating fear, especially in the early stages of the process.If there is a drug that can affect the lobes of almonds, it may have a therapeutic effect on panic and panic.
