The mother of 44 three referred in the journal Current Biology as MS, with a rare emotional disorder due to a genetic disease called fat proteinosis that left holes where the amygdala - threatening brain detector - would normally resident.

The patient felt excitement, but never fear in a series of threatening scenarios monitored by researchers at the University of Iowa, led by Justin Feinstein, a clinical Neuropsychologist.

American woman took her pet store to interact with snakes and spiders, where it has been reported to have exclaimed, "This is so cool!" while rubbing the snake scales and touching his language.

Pet Shop employees had warned about the danger of exotic animals. Previously, the patient also admitted that she hated snakes and spiders. During testing, however, it should be lured away to reach toward a Tarantula.

Requested by researchers to evaluate its fear of 0 to 10, it never exceeded two.

Led by scientists in a "haunted house", Ms approached staff eagerly disguised as monsters, even amazing an interpreter hidden by attacked at the head, thinking that she was "curious" to know how he would feel the mask.

While she viewed as the experience of being "very exciting and fun", comparing it to the feeling of a roller-coaster ride, rating of fear was zero.

Horror like The Blair Witch Project and the shining path also recorded minimum readings for fear of it.

Scientists are studying MS for more than two decades, with several articles on his fear-related anomalies.

While she recalled feeling fear as a child, after a meeting with a snarling Doberman pinscher scary that it forced, she could not recall fearing anything in adulthood.

Overnight in 1995, a strange man fried to a park bench and pressed a knife to her throat, threatens to cut.

"If you're going to kill me, you'll pass by the angels of my God," she replied, he quietly watching. Then, she left and returned to the Park the next day.

Scientists seek to conduct DM coach react differently in such dangerous situations.

"It's quite remarkable that she is still alive," said Feinstein, noting that she presented itself unduly dangerous scenarios because of his inability to deal with fear.

Researchers believe that understand how works of spirit of the DM can assist with the discovery of treatments for PTSD.
