Answer and Explanation:
In the late 1970s, the scientist Roger Sperry developed studies on the functioning of both cerebral hemispheres, warning of the importance of balancing the right and left sides of the brain through exercises that stimulate both: logical thinking and the creativity. Basically the conclusion of his work tells that if you often solve problems "logically," that means you are using the left side of your brain more. But if your choices are mostly driven by "emotion," that means you use the right side of the brain more.
Roger Sperry was an american scientist who won the 1981 Nobel Prize for Medicine and Physiology in proposing brain division into hemispheres and functions. He was a neurobiologist and physiologist and had developed a technique for treating epilepsy called split-brain surgery, which was performed to reduce the risks of nerve impulses and seizures from epilepsy by separating a set of fibers that connect both sides of the brain.
After the first surgeries, Sperry noticed changes in patient behavior and, after clinical analysis and follow-up, found that the corpus callosum had the function of integrating the cerebral hemispheres for balance, between logic and creativity of thought. He concluded that the right and left sides of the brain perform different but complementary functions in shaping ideas and concepts that guide each individual's choices.
