The human brain comprises two hemispheres separated by a bundle of nerves. The left brain controls movement for the right side of the body, while the right brain directs the left side. Different neural regions are responsible for different functions, such as information processing, short-term and long-term memory storage, sensory-data collection, language ability, logical reasoning, and more. One widespread theory about the brain suggests that people who are left brain dominant are more quantitative and analytical, while right-brained individuals are more creative free spirits; however, there is no evidence to support these classifications. On the contrary, most behaviors and abilities require the right and left side of the brain to work together to achieve a common objective.
