Split Brain
Our brain weighs about three pounds and is divided into two similar looking, but different hemispheres, the right and the left. Both are connected to a large bundle of nerves, called corpus collosom. In some people with sever seizer disorders such as epilepsy, it was found that if this bundle of nerves were severed their seizers would stop or at least be under better control. From this surgical procedure, it was discovered that the two hemispheres had different methods of processing information, as well as controlling parts of the body. The left controls the right and the right controls the left. We rely on both hemispheres to process different information; we tend to naturally have one hemisphere that is more dominate than the other. While the brain is an organ that can be seen and held the mind is quite another matter. The mind remains unseen and physically immeasurable, yet appears to be part of us that controls everything. Roger Sperry pioneered this surgical procedure called commissurotomy. The commissurtomy surgically separates the hemispheres, making the transfer of in
I have to call my daughter ('Epilepsy & the Corpus Callosum' 1985) It was once thought that if the neurons were destroyed, that they are gone forever and will not be replaced. Researchers found that when the brain was surgically separated, each hemisphere continued to have individual and private experiences, sensations, thoughts, and perceptions (wood and wood 64). Consequently, many people have often tried to become more "right brain" or "left brain". Mark Rayport, a neurosurgeon in Ohio, had a patient who reported dramatic inter-hemispheric competition for three years following surgery:" I open the closet door. However, there is still substantial documentation on effects sometimes referred to as 'Alien hand' syndrome. Boston: Allyn and Bacon 2002Hellige, J. "Interhemispheric Interaction: Models, Paradigms, and Recent Findings" In Duality and Unity of the Brain: Unified Functioning and Specialization of the Hemispheres. Much of the research done today suggests that the left hemisphere is better at verbal, analytic, sequential, reductive-into-parts, and time oriented tasks, while the right hemisphere is better non-verbal, holistic, synthetic, visual-spatial, intuitive, and timeless tasks.
