Recording from single neurons in the brain has shown that neurons responding to specific types of stimuli are often clustered in specific areas. These results support the idea of localization of function.
Localization of function is an idea used in neuroscience. It refers to the idea that functions can be attributed to specific regions of the brain (different brain areas are specialized for different functions).
