Researchers from the University of Chicago Research concluded that overly aggressive people have small brains. Full details of this study are published in the scientific source Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.
American scientists have identified the dependence of the manifestation of aggression in people and the amount of gray matter in their brain. It turned out that often evil people have small brains. Such conclusions were made by scientists from the research University of Chicago.
This scientific work was supervised by Emil Kokkaro. The scientist said that in the course of their research work, they analyzed about 170 results of magnetic resonance imaging. More than 50 subjects suffered from episodic control disorder syndrome. Thus, specialists in the field of medicine were able to notice that people with frequent impulses of aggression have the least amount of gray matter in the brain than people who do not complain of mental disorders.
