In recent years, research has shown that there is a link between crimes and antisocial behavior. This is seen through genetics, which correlate to the brain and finally turn to antisocial behavior. According to Adrian Raine, genes play a significant role in structural and functional alterations. Evidence has shown that 50% of antisocial behavior are connected to genetic influences. (Moffitt, 2005), cited in, Raine (2008). One of the genes that influence antisocial behavior is the monoamine oxidases A (MAOA) gene. In a study, researchers found that by canceling out the gene from mice, it caused the mice to act extremely aggressive. Which then the researchers put back the gene turning the mice to become normal again. Cases et al.(1995) cited in (Raine, 2008). Over the years, researchers have found a total of seven genes that relate to antisocial or aggressive behavior but also, affect brain structures. For example, one of the genes MAOA cause a reduction in volume in the ventral prefrontal cortex. This was found in males with a variant of the gene. Meyer-Lindenberg et, al., (2006) cited in (Raine,2008) This part of the brain is involved in emotions which plays a role in antisocial behavior.( Raine,2008). Therefore, expressing how genes affect antisocial behavior in individuals.…show more content…
Raine also explains how to treat individuals who have antisocial behavior. The simplest answer is through nutrition. According to Raine (2008), children who experience poor nutrition in the first three years of their lives is related to long-term antisocial behavior. Furthermore, poor nutrition leads to lower IQ which in turn, causes impairments to the brain. Research has shown by giving prisoners Fish oil and dietary supplementations it increases IQ. This also leads to a reduction in antisocial behavior. (Gresch, Hammond, Hampson, Eves,&Criwder,2002), cited in
