The Criminal Brain

Most criminal brains work differently than the average human brain. Some criminals turn to crime after a rough childhood, but criminals who are psychopaths and have personality disorders their minds are wired for it. Here are 10 interesting facts about a criminal's brain.
1. Parts of a criminal's brain are deformed- Some parts in their brains are not all the same size like they should be. Two parts of the frontal lobe are smaller in people who have antisocial personality disorder, they have the tendency to act violent and become repeated offenders. One part was 18% smaller and the other was 9% smaller in the antisocial compared to the normal. Also it is found that the amygdala has a volume of about 18% smaller and that's where human emotion is found.
2. There could be a tumor- It is not common for a criminal to have a brain tumor, but it has been found that some do have brain tumors and that would be in control of their unthinkable acts.
3. Chemical levels in the brain could be off- Some criminal brains have different levels of neurotransmitters like serotonin or dopamine than a normal brain. The serotonin in the brain when its at a proper level keeps people from acting aggressively when they get frustrated, so when this chemical is lower people may act impulsively and violently. Dopamine levels in the brain will affect whether a person will feel rewarded, so if this chemical increases while the person is acting aggressively he/she will more likely feel good about doing it and do it again.
4. The brain won't respond to facial expressions- Psychopaths may not have brains that register fearful expressions on other's faces. Psychopaths have a harder time knowing when an expression is sad. They have almost no reaction to the expression of fear, while normal people's brains get active when they see a scared expression.
5. They are fearless- Psychopath's brains don't react with fear as frequently as normal people's do. They lack the fear conditioning that causes normal people to be afraid when they know fear is coming. The lack of anxiety over the future and the consequences can result in a very dangerous criminal.
6. Warning signs as early as the age of three- Researchers tested a group of three-year-olds to certain sounds and they expected them to have a measurable reaction when they knew an unpleasant sound was coming up. Only 8% of children didn't have any reaction to the bed or frightening sounds. Then about 20 years later they found that about 8% had criminal records for crimes ranging in severity from violent or serious driving infractions.
7. The rational side and irrational side communicate too much- The corpus callosum connects the rational left side of the brain to the irrational right side of the brain. This bundle of fibers in psychopaths is longer and thinner than it is in the average person. It also has more activity which means more communication between the two hemispheres. This can often lead to more impulsive behavior.
8. They're genetically predisposed to crime- There is research that to support the idea that many criminal brains are genetically prone to aggressive or illegal behavior. Some criminals happen because of their environment, but a large number of murders were raised in conflict-free households. They were born with a trait that gave them a higher likelihood of becoming violent criminals. Their brains are more inclined to them than the average humans.
9. Teens' brains aren't fully formed yet- Reasoning and judgment are known to mature throughout the teen years into a person's 20s. Teenagers are more impulsive, more susceptible to peer pressure, less likely to look at the long-term consequences of their actions, and less able to think of ways out of bad situations. Aggression can also peak in the teenage years, so a violent teen may not be a violent adult.
10. Smoking while pregnant can lead to children with criminal tendencies- When smoking while pregnant the mother may be harming her baby's brain in a way that is more likely to make them a criminal. Research has shown that the average adult is 31% more likely to have been arrested at some point if their mother smoked while pregnant. Those who have heavily smoker mothers were more likely to be repeat offenders. Nicotine can cause abnormalities in the development of attention and impulse control in the brain.
