The brain of the criminals is anatomically different

The Mayo Clinic in the United States. UU. He conducted a study neuroscientist dedicated anatomical composition of the brain of the criminals. They discovered that the volume of the gyrus of the frontal lobe of the brain of people with antisocial behaviour – the frontal lobe contains the primary motor cortex, i.e., neurons that control the muscles of the body – is 18% smaller than the standard average for individuals without behavior disorders. Another feature of the criminals is the volume declined by 9 per cent of the orbital gyrus.

Previous investigations of several groups of scientists dedicated to the analysis of behavioral reactions guesses that antisocial behaviour is characterized by the lack of empathy and feelings of shame and guilt, which equals the criminals with people with mental disorders in that regard. It is a proven fact that a serious mental disorder presupposed deformation of the cerebral amygdala: reduces a 18% compared to the individuals in the control group. The amygdala is a set of nuclei of neurons whose primary role is the processing and storage of emotional reactions.

A team of specialists from the University of Pennsylvania study conducted with 1795 children over 20 years, with ages between 3 and 23 years, analyzing various aspects of their growth and development.

When participants were 3 years old passed a test to measure your response to fear. The children heard a sound and received a tiny electric shock. In the majority of children during the subsequent experiments the same sound separately caused a reduction in involuntary muscles. However, in another part of the participants was not developed the automatic reflex of fear. Scientists say that the majority of this part of children, some 137, then became criminals.

However, the initial biological parameters cannot be considered as essential factors which predetermine future criminal. The experts that are dedicated to studying the development of the brain comment that both the anatomical composition and the functioning of the cortex, can change over time, even in middle age already.

In addition, there are some cases in which an offender leaves their anti-social activities and changes his life completely. To perform a series of studies, American experts from the University of Pittsburgh revealed that the brain of a person who in the past was a criminal is not distinguished from the brain of a criminal ‘in asset’.

As for the aggressive activity in children caused by anatomic characteristics of his brain, physiologists comment that at an early age, it is possible to compensate for the reduced volume of an area with a special diet. The main ingredient of the diet is the liver oil of cod, which is capable of stimulating the increase in the number of nerve cells in areas with a volume deficit and thus reduce inclination to aggression and violation of social norms.

Psychologists added that it is easier to educate children who suffer from emotional reactions weakened (lack of some kinds of feelings) appreciate his good behavior rather than punish them if they do something wrong.
