NASA scientists taking a peek at Rain-Man's brain

NASA scientists are scanning the brain of a Utah man who was an inspiration for the 1988 hit movie "Rain Man" in hopes that the technology used to study the effects of space travel on the brain will help explain the mental capabilities and inconsistencies of Kim Peek.

He's called a "mega-savant" because he is a genius in about 15 different areas, from history and literature and geography to numbers, sports, music and dates. He is also severely limited in other ways. Ask him where the silverware is kept and he likely won't know. He doesn't do simple things. He can't dress himself. He may not be able to figure out the light switch, his father Fran says. But Kim Peek's mental abilities in certain categories seem to be getting even stronger with age. That's one reason scientists in California are so interested in running tests.
