It is hoped that such research may make it easier to identify and catch serial killers in the future. 'One most likely reason is that although I have the genetic makeup of a "born" psychopath, some of those very same "risk" genes in someone showered with love (versus abuse or abandonment), from childbirth through the critical first few years of life, appear to offset the psychopathy-inducing effects of the other "risk" genes.' Writing in The Guardian, Professor Fallon said: 'Why, in the light of the fact I have all of the biological markers for psychopathy, including a turned off limbic system, the high risk genetic alleles, and the attendant behaviours, including well over half of those listed in the psychopathy tests and low emotional empathy, did I turn out to be a successful professor and family man? He now believes childhood experiences may also act as some sort of trigger that combines with these other factors to turn someone into a serial killer or a psychopath. He brutally murdered at least 30 women, confessing to the homicides shortly before being put to death in 1989 
Serial killer Ted Bundy (pictured) was one of the most notorious in American history. Scans of his son's brain showed normal orbital cortex activity.
Perhaps most surprisingly he found that his own brain scans show the same low orbital cortex activity as a serial killer. His work has shown that some people's brains appear to be predisposed towards violence. He found low activity in the orbital cortex seems to be involved in sociopathic behaviours and have trouble suppressing rage and violence.
Research by Professor Jim Fallon, a neuroscientist at the University of California, Irvine, has also been studying the brains of psychopaths using brain imaging. This ultimately leads them to feel a lack of empathy for their victims. Similarly Richard Speck, who tortured, raped and murdered eight student nurses in Chicago, had an extra Y chromosome.ĭr Morrison has also said serial killers tend to develop a sense of detachment from the rest of the world from a very early age. This may interact with brain activity and childhood experience Researchers have also found psychopathic tendencies may be passed down through families and could be linked to a gene known as the Warrior gene, or MAO-A, which regulates the mood hormone serotonin in the brain (illustrated above).
