The human brain is a very complex organ that controls everything that makes us who we are. The function of the brain is divided into two hemispheres, each responsible for different aspects of the thinking process. The left and right hemispheres affect learning by directly controlling the process in which information is analyzed using the specific function of each hemisphere. The two hemispheres of the brain are the left and right hemispheres. Each has its own unique purpose and function. The two hemispheres are separated by a central fold connected only by a thick nerve cord called the corpus callosum. The left hemisphere is believed to be the logical side that controls speech, reading, writing, details, facts, mathematics, science, and rational, literal, and practical analysis. The right hemisphere is believed to control the intuitive and creative side of life, with spatial perception, symbols and images, facial recognition, imagination, beliefs and fantasy. (Vered, 2013, www.brainskills.co.uk) These two hemispheres are thought to function independently when separated from each other. The idea that these two hemispheres of the brain can coexist independently functioning as separate conscious minds is interesting. An idea that was explored in 1981 by Roger Sperry. He pioneered the study of what he called “split-brain” patients. A “split-brain” patient is a person who has had the two hemispheres of the brain disconnected to treat severe epilepsy. The left hand and eye provide data to the right hemisphere, while the right hand and eye provide data to the left hemisphere. Tests were conducted in these “split brain” patients to show that each half was isolated from the other. These same tests made it possible to evaluate the efficiency and potential of each half.
