Oddly enough, the brain can tell a lot about a person. I have always been interested how the brain of a normal person differs from the brain of a serial killer. What drives these people to do these awful things? Is there even anything that drives them to do these things or are they just one in a million?
Helen Morrison, a forensic based psychiatrist, has interviewed many serial killers and found many similarities. She has come to the conclusion that one of the triggers may be a chromosome abnormality. She found that this chromosome abnormality begins to show itself during puberty and is especially prominent in men who display their homicidal tendencies. When killing victims, brain scans show that they never develop a form of attachment or belonging to the world which makes it easier to kill.
Jim Fallon, a neuroscientist, has studied the brains of psychopaths for over 20 years and found that they have low orbital cortex activity. The orbital cortex is in charge of behaviors. If you have low activity in this region that means that there is less normal suppression of behaviors, including rage, violence, eating, sex, and drinking. This change in the brain could be the result of many things including child abuse. Many serial killers have experienced child abuse, psychological abuse, and/or maltreatment. Fallon’s research made him come to the conclusion that childhood experience could make all the difference when it comes to the making of a serial killer.
You don’t have to be enlightened to realize that there is something wrong/different with serial killers. There is a lot of medical evidence that shows us this. For example, the two people above who talked about the differences in the brain of a serial killer. There are many differences and disorders shown. In most cases, as a child they suffered home issues but in others this may not be the case.
