Snakes, spiders, haunted houses and horror movies may frighten most of us, but there is one woman who doesn’t seem to be afraid of them or anything else.
Identified only as ‘SM’, she is the subject of a new study that looked at how a certain part of the brain experiences fear.
Researchers at the University of Iowa have found an almond-shaped structure in the brain, called the amygdala, which develops the emotion of fear.
Earlier studies have shown that the amygdala plays a key role in generating fear in animals.
The new study confirms for the first time that the amygdala triggers fear in human beings too.
