There’s a theory suggesting that certain activities of the brain have been divided into the two hemispheres. This theory also suggests that many people prefer one side (or method) of brain function over the other. The western culture as opposed to the eastern cultures tends to prefer teaching to deploy the left brain more-so than the right.

Physiologically, brain functionalities are also divided. In other words each half of the brain controls one half of the body. However, the functions are inverted, in so much that each side of the brain controls the opposite side of the body. (Right Brain = Left side). This issue presents a paradox, because most artists use both hands when creating. Therefore, the entire brain is at work coordinated in such a way that what is expressed in art creation is indeed a combination of both sides.
