Excerpt from NPR:
The criminal brain has always held a fascination for James Fallon. For nearly 20 years, the neuroscientist at the University of California Irvine has studied the brains of psychopaths. He studies the biological basis for behavior, and one of his specialties is to try to figure out how a killer’s brain differs from yours and mine.
About four years ago, Fallon made a startling discovery. It happened during a conversation with his then 88-year-old mother, Jenny at a family barbecue.
“And I said, ‘Jim, why don’t you find out about your father’s relatives?'” Jenny Fallon recalls. “I think there were some cuckoos back there.”
