Split-Brain Theory refers to a concept in neuroscience that explores the functions of the two hemispheres of the brain, particularly after surgical procedures that sever the corpus callosum. This structure connects the left and right hemispheres, allowing them to communicate. When this connection is disrupted, each hemisphere can operate independently, leading to unique behaviors and cognitive functions. Research on Split-Brain Theory has revealed that the left hemisphere is typically associated with language and analytical tasks, while the right hemisphere is linked to creativity and spatial awareness. Studies involving split-brain patients have provided insights into how each hemisphere processes information differently, enhancing our understanding of brain function and lateralization.
