This paper focuses on the brain. The most complicated part of the brain is the cerebral cortex made up of the right hemisphere and left hemisphere with each having four lobes. The cortex is full of wrinkles and folds. Each of the hemispheres has their own unique way of processing information. The right hemisphere is more holistic, visual spatial, and intuitive. The left hemisphere is more linear, verbal analytic, and logical. The cerebral hemispheres control the opposite sides of the body (Savage 2002).
