Localization of function refers to the idea that different areas of the brain are responsible for specific functions. Synonyms for localization of function include cerebral specialization, brain lateralization, and cortical mapping. These terms all highlight the idea that certain functions are localized or specific to particular regions of the brain. Other related terms include modularity, which refers to the idea that the brain is composed of distinct modules or functional units, and functional segregation, which emphasizes the separation of different functions within the brain. These concepts are important for understanding how the brain processes information and for developing effective treatments for neurological disorders.
