The initial premise of this web search was to determine what differences, if any, were known to exist in the brain of the ambidextrous individual.

The debate over the 5% to 30% who are not "right-handed" finds that they might be classified as: ambidextrous, left-handed, or non-right handed, depending on the individuals particular traits and by whom they are scrutinized. In relation to brain lateralization those individuals not characterized as "right-handed" tend to have, as a group, a less predictable pattern of specialization (3). A contrasting approach to addressing the "left-handed" and ambidextrous persons dispersed processes would be to conceive of the "right-handed" as dextrally bias (1).

In popular culture individuals have often been classified as "right or left -brained". This classification has to do with those functions generally specialized in each hemisphere. "Left-brained" individuals are deemed strong in those functions localized in the left hemisphere, which include: number skills, written language, reasoning, scientific, and the spoken language. While a "right-brained" individual proves characterized by those functions localized in the right hemisphere, which include: insight, 3D spatial reasoning, art awareness, imagination, and music awareness
