Kim Peek

- Though Kim Peek is a savant, he has some exceptional brain abilities. He is lacking a functional corpus callosum (which makes it impossible for his right and left brain hemispheres to exchange information) and has a damaged cerebellum. Without a corpus callosum, some develop above average memory abilities. In Kim Peek’s case, he can read a new book in about 1 hour and manages to retain over 98% of the information within the book! Impressive.

Laurence Kim Peek (November 11, 1951 – December 19, 2009) was an Americansavant. Known as a "megasavant", he had an exceptional memory, but he also experienced social difficulties, possibly resulting from a developmental disability related to congenital brain abnormalities. He was the inspiration for the character of Raymond Babbitt, played by Dustin Hoffman in the movie Rain Man. Unlike Babbitt, Peek had FG syndrome.

Peek was born in Salt Lake City, Utah with macrocephaly, damage to the cerebellum, and agenesis of the corpus callosum, a condition in which the bundle of nerves that connects the two hemispheres of the brain is missing; in Peek's case, secondary connectors such as the anterior commissure were also missing. There is speculation that his neurons made unusual connections due to the absence of a corpus callosum, which resulted in an increased memory capacity. According to Peek's father, Fran Peek, Kim was able to memorize things from the age of 16–20 months. He read books, memorized them, and then placed them upside down on the shelf to show that he had finished reading them, a practice he maintained. He could speed through a book in about an hour and remember almost everything he had read, memorizing vast amounts of information in subjects ranging from history and literature, geography and numbers to sports, music and dates. According to an article in The Times newspaper, he could accurately recall the contents of at least 12,000 books. Peek lived in Murray, Utah.
Peek did not walk until the age of four and then in a sidelong manner.[ He could not button up his shirt and had difficulty with other ordinary motor skills, presumably due to his damaged cerebellum, which normally coordinates motor activities. In psychological testing, Peek scored below average (87) on general IQ tests.
