Mad Science

By Marlowe Hood

NEW YORK — Psychopaths are known to be wily and manipulative, but even so, they unconsciously betray themselves, according to scientists who have looked for patterns in convicted murderers' speech as they described their crimes.

NEW YORK (AP) — It sounds like science fiction: While volunteers watched movie clips, a scanner watched their brains. And from their brain activity, a computer made rough reconstructions of what they viewed.

Scientists reported that result Thursday and speculated such an approach might be able to reveal dreams and hallucinations someday.
