Right and left spheres of brain have an important role in shaping individuals’ talents and guiding their behaviours. Although it is too naive to explain this concept here in one page I wanted to point out the essence of the issue by Neurologist Dr. Mehmet YAVUZ’s short blog on the subject and comments of a writer and educator Kendra CHERRY, who specializes in making psychology more understandable for students.
The right brain-left brain theory grew out of the work of Roger W. Sperry, who was awarded the Nobel Prize in 1981. While studying the effects of epilepsy, Sperry discovered that cutting the corpus collosum (the structure that connects the two hemispheres of the brain) could reduce or eliminate seizures.
However, these patients also experienced other symptoms after the communication pathway between the two sides of the brain was cut. For example, many split-brain patients found themselves unable to name objects that were processed by the right side of the brain, but were able to name objects that were processed by the left-side of the brain. Based on this information, Sperry suggested that language was controlled by the left-side of the brain.
Later research has shown that the brain is not nearly as dichotomous as once thought. For example, recent research has shown that abilities in subjects such as math are actually strongest when both halves of the brain work together.”
