In their research, they have found a positive relationship between criminal behaviors and genes. Brunner et al(1993) conducted an research on a Dutch family, the result showed that some of the family members from the Dutch family with tendency of aggressive behavior turned out to have mutation occurring in their monoamine oxidase A, a type of neurochemical in the brain. Therefore, we tell say that aggressive behavior is somehow related to human brain structure. In addition, Vergnes pointed out that our brain regions other than the amygdala, also the area called hypothalamus and periaqueductal gray are related to human aggressive behavior. Also it has been shown through several experiments that the increase of serotonergic synapse, a type of neurotransmitter, in our brain will constrain aggression behavior on human. Because of this, some psychological therapist would use the serotonergic drugs to use against aggressive behavior. One of a research conducted at the University of Texas supported the relationship between serotonergic synapse and aggressive behavior. The…show more content…
