The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive sensory input, motor areas control movement of muscles.Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.The central sulcus divides the primary sensory and motor areas.Both the sensory cortex and the motor cortex have been mapped out according to what part of the body it controls.ssociation areas are involved with more complex functions such as learning, decision making and complex movements such as writing.
