Savants

An autistic savant (historically described as idiot savant) is a person with extraordinary mental abilities, often in numerical calculation, but sometimes in art or music. These skills are often, yet not always, associated with autism or mental retardation.

Abilities
A person with an extraordinary single mental skill but an otherwise unexceptional intellect, may be described simply as a savant, without qualifier, although savant is also frequently used figuratively to mean a person of learning, especially one of great knowledge in a particular subject, without regard to the person's overall intellect.

True savantism is usually recognized during childhood and is often found in children with autism and occasionally in children with other developmental difficulties. However it can also be acquired in an accident or illness, typically one that injures or impairs the left side of the brain. There is some research that suggests that it can be induced, which might support the view that unusual savant abilities are latent within all people but are obscured by the normal functioning intellect. By the help of repetitive transcranial magnetic stimulation researchers are providing empirical evidence for the hypothesis that savant-like skills can be approved in a healthy individual by temporary disruption of the left front part of the brain - at least with some of the probates.

Most autistic savants have very extensive mental abilities, called splinter skills. They can memorize facts, numbers, license plates, maps, and extensive lists of sports and weather statistics. Some savants can mentally note and then recall perfectly a very long sequence of music, numbers, or speech. Some, dubbed mental calculators, can do exceptionally fast arithmetic, including prime factorization. Other skills include precisely estimating distances and angles by sight, calculating the day of the week for any given date over the span of tens of thousands of years, and being able to accurately gauge the passing of time without a clock.

Why autistic savants are capable of these astonishing feats is not quite clear. Some savants have obvious neurological abnormalities (such as the absent corpus callosum in Kim Peek's brain), but the brains of most savants are anatomically and physiologically normal; at least, there is no abnormality detectable by modern science.
