Association areas are parts of the cerebral cortex that receive inputs from multiple areas; association areas integrate incoming sensory information, and also form connections between sensory and motor areas. Because they are involved in organizing information that comes from various other areas of the brain, association areas are often linked to complex functions. Association areas regulate intersensory association, communication and memory. Whereas the Limbic system is responsible for the regulation of sexual behaviour.
