Document Summary
Primary sensory cortex - makes you aware of a sensation. Association areas - gives meaning to/make associations with a sensation. Multimodal association areas - make associations between different types of stimuli: motor areas - allow you to act upon a sensation. Primary motor cortex - sends signals to generate movements. 2 special motor cortices (frontal eye friend, broca"s area for speech) Homunculus - motor and sensory: homunculus of primary somatosensory cortex in blue. Each hemisphere receives info from the opposite side of the body. Different body parts require different amounts of the cortex. Functional areas - lateral view (l: functional areas of the cerebral cortex. Functional areas - parasagittal view (r: functional areas of the cerebral cortex. Action vs. movement: action - the outcome of a number of cognitive processes that translate the goals and intentions of an individual into a motor output.
