Educação pode mudar sua vida

What makes a teenager grow up to live a normal life while¹ another turns to murder?
Researchers suggest the answer may lie in a part of the brain that controls planning, reasoning and impulse control. Studies are revealing physiological differences between² the brains of normal people and those of people who kill.
"There is clearly a biological predisposition to violence", says psychologist Adrian Raine of the University of Southern California. "We know there are murderers who don’t have the usual signs – a history of child abuse, poverty, domestic violence, broken homes – and yet³ they commit violence. Research suggests the cause may lie internally, in terms⁴ of abnormal biological functioning".
Raine led studies comparing⁵ the brains of 41 murderers with those of 41 nonviolent⁶ people matched by age and gender. He found that ‘‘murderers have poorer⁷ functioning of the pre-frontal cortex, the part of the brain located above⁸ the eyes, behind the forehead. This is the part of the brain that controls regulating behaviors – the part that says 'wait a minute⁹'".
In another study, Raine divided the murderers into two groups: those from healthy, stable family backgrounds and those from¹⁰ abusive, dysfunctional homes. "It’s the murderers from good home environments who have the poorest brain functioning", he says.
