Gerhard Roth measured brain activity in violent criminal offenders and found a ‘dark patch’ in the frontal lobe. He recommends taking it out. That sounds like a labotomy. Fox news published an article covering Dr. Roth’s work. Jeremy A. Kaplan writes:
“After studying the brains of violent killers, rapists and robbers, German neurologist Gerhard Roth claims to have found a “dark patch” in the center of the brain — he calls it the evil spot, a genetic source of violent behavior.
Roth, a professor at the University of Bremen, told Germany news site Bild.de that he had shown short films to criminals and measured their brain activity. A small section at the front of their brains showed no reaction to violent scenes; it remained “dark” when shown dark scenes.
“Whenever there were brutal and squalid scenes, the subjects showed no emotions. In the areas of the brain where we create compassion and sorrow, nothing happened,” Roth said.”
Dr. Steven Maletta disagrees from NYU believes that violent behavior is more complex. He is quoted for this article:
“Certain areas are likely important for certain behaviors, certain attitudes. But it’s probably not as simple as X marks the spot for a particular behavior.”
Brain tumors can also cause violent behavior, the article continues:
“Terre Constantine, executive director of the Brain Research Foundation and the former director of the Jack Miller Center for Peripheral Neuropathy, expressed skepticism at the report, but agreed that brain abnormalities such as tumors can affect behavior.”
