What is the difference between the brains of murderers?

For years, police and psychologists have been trying to find a way to get inside the brains of murderers, but they haven't found anything yet. Now they are getting ever closer to the unusual things in this brain of this subject.

Adrian Raine, University of Southern California psychologist - Adrian Raine (Photo: bbc) Ted Bundy, Jeffrey Dahmer, David Berkowitz are notorious serial killers who must be disgusted when they hear anyone. What did they think? What happened in their heads? Is their brain different?

Normal brain and brain of murderer, who has bad behavior

Adrian Raine, Professor of Psychology at the University of Southern California has tried to find answers to these questions by observing the brains of these murderers. He had to use two scanning techniques: The positron X-ray technique (PET), which allowed him to know how the brain's function worked; and MRI techniques that help him study the structure of the brain.

Raine compared the brain function and structure of 41 murderers and 41 probes and found a lower flexibility in the prefrontal cortex (the area above the eyes and the forehead) of murderers when compared to the flexibility of people under normal detention. Raine explained that the prefrontal cortex acts as 'brakes' in the human brain, and since these individuals have poor brain function before the forehead, they cannot control and adjust. get your feelings. However, Raine said that, although there are many links between the frontal function and aggression, the abnormal behavior of the brain cannot be the only reason for violent behavior, but there are also reasons. Other reasons such as environment and society have much greater influence that makes an individual a killer.

Normal brain (left) and problematic brain (Photo: cand) He divided these murderers into two groups of 'easy-moving' killers and 'beasts' groups to study differences in their brains (emotional instability are those who kill because of impulse; and beasts are murderers with pre-intention). Although some of them cannot determine which group belongs to either group, Raine can choose 15 of the 41 names in the beast group and 9 names on the impulsive group. He found that, while impulsive murderers had less flexible frontal brain function, the frontal activity of beast killers was normal. Both groups have higher activity in the area under the cortex than usual, the area is a more primitive and deeper part of the brain.

'This is a part of the brain that increases the sense of aggression more and perhaps stimulates violent behavior' - Raine said - 'A difference between these two murderous groups is an emotional individual. , impulsive, people with a lot of violent emotions, cannot control their behavior because they have inefficient prefrontal brain function. "

In contrast, attempted killers (beastly-style killers) can feel angry and aggressive, but their forehead brains have enough functioning to be able to adjust and control. control and turn your aggressive actions into actions that can make them excited. ' According to Raine, since they carefully planned their actions, it was difficult to catch these cold and savage killers because they were thoughtful and well prepared.

Because the brain is 'infected' early

"It seems that the seed of violence has been cultivated very early in their lives" - Raine said, 'Of course, social factors also play an important role. We know that individuals Any complication at birth or spurned by the parents in the early years of life will often become violent criminals'.

Mr. Raine concluded: What we really need more is to study this area, but research on a form that results in practical application so that we can do something to treat those criminals who kill and do something to help those who are provoked to avoid the path of sin merging with the community
