The Physiology of the Senses

visual visual auditory auditory vestibular vestibular taste taste b Higher order visual Premotor Higher order somatosensory Higher order auditory c Inferior Temporal association Parietal-temporal-occipital association Prefrontal association d The 5 main subdivisions of the cerebral cortex. The primary sensory and motor areas. This is where most of the sensory information first arrives. Primary motor areas send commands to the muscles. In the rat these areas occupy nearly all the cortex. In humans they occupy only about 20%. The higher order (secondary) sensory and motor areas. Higher order visual, somatosensory, and auditory lie near the respective primary areas. This is where sensory information is further processed. These are also called unimodal association areas. Premotor areas send commands to the motor areas. This is where: a) different modalities combine. b) attention is shifted. c) planning occurs. d) things are remembered.
