NASA scientists taking a peek at Utahn'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.

When he was born, doctors found a water blister on the right side of his skull, similar to hydrocephalus. Later tests showed his brain hemispheres are not separated, forming a single, large "data storage" area. It is likely that is why he has been able to memorize books his father numbers at well over 9,000. He has a photographic memory, too. But in other areas he has lagged.

His motor skills developed more slowly and less well than those of his peers. His motor control is poor, though it has improved somewhat with training. He has trouble filtering out distractions, so he sometimes hums or uses other focusing devices to tune those distractions out.

Early in his life, doctors said he had mental retardation and would never be able to do much.

They were wrong, both in the assessment of his condition and the prediction of his future.

In the past 16 years, Peek, now 53, has charmed and enthralled scientists and students, parents and politicians — 2.3 million in all in the course of public appearances that have taken him all over the country, often for days at a time.

It was just such a trip that brought him to the attention of NASA researchers at the Center for Bioinformatics Space Life Sciences at the NASA-AMES Research Center in central California.

Last week, researchers subjected Peek to a number of scanning techniques including computerized tomography and magnetic resonance imaging, the results of which will be melded to create a three-dimensional look at his brain structure. Researchers hope the tests will answer some of the questions about the human brain, from its origin to how it works.

Not only are Peek's brain and his abilities unique, noted Richard D. Boyle, director of the center, but the fact that he seems to be getting smarter in his specialty areas as he ages in unexpected, too.
