What is lateralization of the brain, and why does it occur?
What will be an ideal response?
Answer: The cerebral cortex has two hemispheres, or sides, that differ in their functions. The specialization of functions is called lateralization. Studies using fMRI reveal that the left hemisphere is better at processing information in a sequential, analytic way, a good approach for dealing with communicative information—both verbal and emotional. In contrast, the right hemisphere is specialized for processing information in a holistic, integrative manner, ideal for making sense of spatial information and regulating negative emotion. A lateralized brain may have evolved because it enabled humans to cope more successfully with changing environmental demands. It permits a wider array of functions to be carried out effectively than if both sides processed information in exactly the same way. However, the popular notion of a "right-brained" or "left-brained" person is an oversimplification. The two hemispheres communicate and work together, doing so more rapidly and effectively with age.
