The fearless person

Snakes, spiders, 'ghost' houses and creepy horror movies . are topics that every time they mention or witness, there will be many people who are scared to the point of bumps and hairs standing up. up, but there is a woman in the world who is not afraid of any of them, she is not afraid of anything.

Strange fate of fearless woman

It was an American woman, the protagonist would be allowed to remain anonymous but only carry the name sign with the words 'S.M', currently living in a poor neighborhood, where many dangerous crimes are taking place. dangerous. Her anonymity was meant to help this woman avoid being murdered from criminal gangs and the strange case of this woman was quoted in the scientific journal ' Biology contemporary '.

Neuroscience researchers at the University of Iowa in Iowa City, Iowa (USA) are in the midst of studying SM's case for a long time because her case is particularly rare. it damaged the Amygdala lymph nodes on both sides of her brain. Amygdala is an almond-shaped structure that plays an important role in forming fear and other emotional states, although experts say that the true role of this structure is still unknown. very clear.

Amygdala lymph node on the brain of SM woman
has no longer displayed.

Amygdala damage in SM women is caused by Urbach-Wiethe disease (this is a rare disease, it is an inherited disorder, causes calcium deficiency and Amygdala lymph node damage ). According to Daniel Tranel, one of the study authors and professor of neurology and psychology at the University of Iowa, said: 'We want to know: Whether or not a common form of fear has responded. to SM causing fear agitation? '. In order to identify the implications for this rare case in response to fear, Daniel Tranel and his colleagues have exposed SM in turn to things that ordinary people feel scared like spiders. , snakes, one of the 'ghost' houses and watch horror movies. At the same time, they conducted a lot of questions about SM's fear syndrome during the three-year experimental period and also asked how SM feels to assess different levels of emotion at times. Random points for a period of 3 months.

SM said that she had no impression of the "torture" of scientists as well as reports that SM still maintained her normal feelings during the tests. . On the other hand, SM also expressed other emotions such as joy, happiness and sadness. In the past, SM had collided with many suffering. She was threatened with death with a gun, with a knife and seemed to die in an accident. SM told the researchers that she had no sense of fear during periods of testing. SM is also aware that she is unable to react to fear while ordinary people scream out of fear. According to Dr. Jon Shaw, a professor of psychiatry at Miami Medical University (USA): ' SM's body didn't have the necessary reactions when scared because Amygdala lymph nodes are not in the brain .' Daniel Tranel said that the study, along with SM's past experiences, has shown that Amygdala lymph nodes play a vital role in responding to fear.

Benefits and harms of the disease are not afraid

SM's eldest son (she has three children) remembers her mother's case as follows: ' I and my brothers are playing in the yard and my mother is sitting on the porch. At that time all three brothers saw a snake crawling along the way. The snake is not afraid of anyone but just comes near us. Too scared, the flood screamed and ran to a corner. I shouted: God. Giant snake! What about my mother? She rushed to the crawling snake, picked it up, placed it on the grass and the straight bull snake. Perhaps she is afraid of my mother too! Once in a gang payment, the bastards shot at my mother, and added another blow to my body, at which time we thought that my mother was going to die because of blood, but strangely my mother was still peaceful. static, not afraid at all, she pecked the bullet herself, bandaged the wound and then gradually recovered. In this story the local police testified '.

The researchers wrote: 'S. M lives clean and has never joined a gang. Life of SM is obviously very dangerous, but she is still indifferent, not afraid even the most severe situations '. SM said that she was not afraid of anything but was angry because the bad things were happening. To confirm this strange disease phenomenon, scientist Feinstein said: ' Unfortunately, patients with this disease are rare and rarely able to bring them to light for further research '. . The US National Institute of Health Research (NIH) and the US National Science Scholarship Fund fund this rare study.
