This illness is a result of the physical brain matter being normal but the way the brain functions is different than other people's brains. During a thermal scan of the brain activity psychopath's brain's bypass the frontal lobe where emotions are usually processed. As a result, they do not feel fear, love, empathy, shame or remorse. They do feel anger, frustration &bordom. Dr. Hare, formost authority on this has studied this for over 20 years. His most revealing tests involve hooking up test subjects to a brain scan machine along with a control group. The subjects then viewed photos that ranged from friendly to horrifically disturbing. The experiments showed the control groups scans as appropriately responsive. The disturbed mind showed no change or flatline. Dr. Hare was quoted as saying that these brain patterns were not human.
