[1] What makes a teenager grow up to live a normal life
while another turns to murder?
Researchers suggest the answer may lie in a part of
the brain that controls planning, reasoning and impulse
[5] control. Studies are revealing physiological differences
between 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
[10] Southern California. ‘‘We know there are murderers who
don’t have the usual signs - a history of child abuse,
poverty, domestic violence, brocken homes - and yet they
commit violence. Research suggests the cause may lie
internally, in terms of abnormal biological functioning.’’
[15] Raine led studies comparing the brains of 41 murderers
with those of 41 nonviolent people matched by age and gender.
He found that ‘‘murderers have poorer functioning of the
pre-frontal cortex, the part of the brain located above the eyes,
behind the forehead. This is the part of the brain that controls
[20] regulating behaviors - the part that says ‘wait a minute’.’’
In another study, Raine divided the murderers into two
groups: those from healthy, stable family backgrounds and those
from abusive, dysfunctional homes. ‘‘It’s the murderers from
good home environments who have the poorest brain
[25] functioning,’’ he says.
