The Real Rain Man Kim Peek was born without a corpus callosum. The bundle connecting the brain's hemispheres. Instead, his hemispheres worked independently. He read left page with the left eye. Right page simultaneously with the right eye. Two pages in about ten seconds. He memorized twelve thousand books.
