Left or Right Brain? What's the Difference?.
A creative person is a person that can process information that is available to everyone. A writer needs words, a musician needs notes, an artist needs visual perceptions, and they all need some knowledge of different techniques of their abilities. Creative people see possibilities for transforming plain data into new creations, beyond the raw material. The human brain looks like the two halves of a walnut. Both halves appear similar, two rounded halves connected at the center. These two halves are called the left and right hemispheres. The nervous system is connected to the brain in a crossover fashion. The left hemisphere controls the right half of the body, and right hemisphere controls the left side of the body. If you suffer a stroke or brain damage on the left half of your brain the right half of your body would be most affected. Because of the crossing over of the nervous system the left hand is connected to the right-brain and the right hand is connected to the left-brain. In the brains of animals, the cerebral hemispheres are basically alike in function. The hemispheres, however, develop asymmetrically in functionality. The most noticeable effect is handedness. .
For the past one-hundred fifty years or so, scientists have known that language and language related functions come mainly from the left hemisphere on most people, approximately ninety-eight percent of right-handers and about sixty-six to sixty-seven percent of left-handers. The knowledge that the left half of the brain controls language came from observations of people that suffered brain injuries. For example, an injury on the left side of the brain would probably cause a loss of speech than an injury of equal damage to the right side of the brain. The left side of the brain is thought to be the dominant hemisphere by nineteenth century scientist because language is so closely related to thinking, reasoning, and higher mental functions.
