Explain what is meant by one being "right-brained" or "left-brained."
What will be an ideal response?
The notion is that the hemispheres of the brain are involved in different kinds of intellectual and emotional activities. Research suggests that the left hemisphere is more involved in intellectual undertakings that require logical analysis, problem solving, language, and computation skills. The right hemisphere is usually superior in visual-spatial functions, aesthetic and emotional responses, and understanding metaphors. But it is not true that children are either "right brained" or "left brained.". The functions of both hemispheres overlap and communication is through the corpus callosum, a bundle of nerve fibers that connect the two hemispheres.
