A Neuroscientist Uncovers A Dark Secret : NPRFirst in a three- part series. Fallon with his wife, daughters and son. When he compared the brain scans of his family — including his wife, siblings, children and mother — his was the only one that resembled the brain of a pyschopath. When he compared the brain scans of his family — including his wife, siblings, children and mother — his was the only one that resembled the brain of a pyschopath. For nearly 2. 0 years, the neuroscientist at the University of California- Irvine has studied the brains of psychopaths. He studies the biological basis for behavior, and one of his specialties is to try to figure out how a killer's brain differs from yours and mine. About four years ago, Fallon made a startling discovery. Warriors of Blue Genetic Killers. Buy link http:// Tracklisting A-Genetic Are killers born with 'murder gene'? Scientists now say they have the answer 12:13,. Some of the world's worst serial killers: VIEW GALLERY.
It happened during a conversation with his then 8. Jenny, at a family barbecue. One of his direct great- grandfathers, Thomas Cornell, was hanged in 1. That line of Cornells produced seven other alleged murderers, including Lizzy Borden. Because he has studied the brains of dozens of psychopaths, he knew precisely what to look for. To demonstrate, he opened his laptop and called up an image of a brain on his computer screen. There are patches of yellow and red. Then he points to another section of the brain, in the front part of the brain, just behind the eyes. This is the orbital cortex, the area that Fallon and other scientists believe is involved with ethical behavior, moral decision- making and impulse control. But in some people, there's an imbalance — the orbital cortex isn't doing its job — perhaps because the person had a brain injury or was born that way.? This is the area that Fallon and other scientists say is involved with ethical behavior, moral decision- making and impulse control. The normal scan on the left is his son's. But he wanted to be sure. Conveniently, he had everything he needed: Previously, he had persuaded 1. PET brain scan and give a blood sample as part of a project to see whether his family had a risk for developing Alzheimer's disease. After learning his violent family history, he examined the images and compared them with the brains of psychopaths. His wife's scan was normal. His children: normal. What he didn't want to reveal was that his orbital cortex looks inactive. Scientists are just beginning to study this area of the brain — much less the brains of criminals. Still, he says the evidence is accumulating that some people's brains predispose them toward violence and that psychopathic tendencies may be passed down from one generation to another. The Three Ingredients. And that brings us to the next part of Jim Fallon's family experiment. Along with brain scans, Fallon also tested each family member's DNA for genes that are associated with violence. He looked at 1. 2 genes related to aggression and violence and zeroed in on the MAO- A gene (monoamine oxidase A). Serotonin affects your mood — think Prozac — and many scientists believe that if you have a certain version of the warrior gene, your brain won't respond to the calming effects of serotonin. Fallon calls up another slide on his computer. It has a list of family members' names, and next to them, the results of the genotyping. Everyone in his family has the low- aggression variant of the MAO- A gene, except for one person. I have the pattern, the risky pattern. He doesn't believe his fate or anyone else's is entirely determined by genes. They merely tip you in one direction or another. They believe that brain patterns and genetic makeup are not enough to make anyone a psychopath. You need a third ingredient: abuse or violence in one's childhood. Significantly, he says this journey through his brain has changed the way he thinks about nature and nurture. He once believed that genes and brain function could determine everything about us. But now he thinks his childhood may have made all the difference. But what about people who rape and murder — should we feel empathy for them? Should they be allowed to argue in court that their brains made them do it? Enter the new world of . Genetic Killers on Apple Music. Discover and share new music, movies, TV, books, and more.
