Answer:
Cortical localization
Explanation:
The theory of localization explains that certain functions are associated with specific areas of brain. According to theory of cortical localization of function different cerebral cortical territories perform different functions, such as vision and language. Such as any damage to Broca's area will render a person to speak although he is able to understand the language. In the same way any damage to ventral occipital lobe/cortical region will cause a problem in color vision.
