Normal vs Psychopath

There was an experiment that was used to see how you can try to tell the difference between a psychopath from a normal person's brain. He decided to get a brain scan of himself and compare it to a known psychopath's brain. He was observing the brain scan and noticed there was no orbital cortex activity and no temporal lobe activity in one of the images of a brain. He assumed it was a killer's brain but then realized it was his own brain and did some research of the high-risk genes and found matches that made him question himself about the behaviors. The family was not surprised at the results because they could see some of the traits or see that something was wrong with him. He admitted that he had some of the traits of a psychopath for example he knows right from wrong but does not care if he is in the wrong. Even if he has the genes it depends on how he grows up and his childhood that determines how he should behave. A normal brain would have regular activity in the orbital cortex and the temporal lobe and not have the traits.
