So we're interested in exactly where in the brain, and what's the most important part of the brain. So we've been looking at this: the interaction of genes, what's called epigenetic effects, brain damage, and environment, and how these are tied together.
And how you end up with a psychopath, and a killer, depends on exactly when the damage occurs. It's really a very precisely timed thing. You get different kinds of psychopaths. So we're going along with this. And here's, just to give you the pattern. The pattern is that those people, every one of them I looked at, who was a murderer, and was a serial killer, had damage to their orbital cortex, which is right above the eyes, the orbits, and also the interior part of the temporal lobe.
So there is the pattern that every one of them had, but they all were a little different too. They had other sorts of brain damage. A key thing is that the major violence genes, it's called the MAO-A gene. And there is a variant of this gene that is in the normal population. Some of you have this. And it's sex-linked. It's on the X chromosome. And so in this way you can only get it from your mother. And in fact this is probably why mostly men, boys, are psychopathic killers, or are very aggressive.
Because a daughter can get one X from the father, one X from the mother, it's kind of diluted out. But for a son, he can only get the X chromosome from his mother. So this is how it's passed from mother to son. And it has to do with too much brain serotonin during development, which is kind of interesting because serotonin is supposed to make you calm and relaxed.
