The idea that the human brain is divided into a logical left half and a creative right half has become one of the most enduring metaphors in psychology and popular culture. While this simplification obscures the complexity of neural processing, it points to a genuine biological reality. The brain is structurally and functionally divided into two hemispheres, each specialized in subtle but important ways. Understanding why this split exists and why each hemisphere controls the opposite side of the body reveals much about human evolution, perception, and behavior (Corballis, 2014).
