Scientists Study Woman With No Fears
Is there anything you're not afraid of? Imagine what it must be like to never experience fear of any kind.
A woman with a rare genetic disorder, Urbach-Wiethe disease, isn't frightened by anything – haunted houses, spiders, snakes, movie monsters, death threats, being attacked or robbed, the Live Science website reports.
Researchers at the University of Iowa have done their best to scare the 44-year-old woman, identified only as "SM" for confidentiality reasons.

An undated image of a brain scan provided by the University of Iowa Department of Neurology shows MRI scans of patient SM's brain. The arrows point to the amygdala, the region of the brain that SM is missing, as shown by the vacant black holes underneath the arrows.
Writing in the journal Current Biology, study co-author Justin Feinstein indicates that SM's Urbach-Wiethe condition has damaged her amygdala, an almond-shaped portion of the brain that may be connected with "abnormal fear reactions and a reduced experience of fear."
"We conducted a new study in a rare human patient, SM, who has focal bilateral amygdala lesions," Feinstein and his colleagues wrote.
"To provoke fear in SM, we exposed her to live snakes and spiders, took her on a tour of a haunted house, and showed her emotionally evocative films."
