Cerebral cortex

  1. Primary sensory area (Post-central gyrus) Parietal Lobe
    • Image Upload 1
    • Where we first become consciously aware of a sensation. body region being stimulated is identified via spatial discrimination.
  2. Somatosensory association cortex (Parietal Lobe)
    Produces an understanding of sensory inputs. Would not be able to recognize objects without looking at themImage Upload 2
  3. Somatosensory homunculus
    shows the relationship of body part sensitivity relative to what its size would be
  4. Primary visual cortex (Occipital lobe)
    Produces visual sensations from neural impulses originating from the eyeImage Upload 3
  5. Visual association area (occipital lobe)
    uses past experiences to make sense of what is presently seenImage Upload 4
  6. Primary auditory area (temporal lobe)
    pitch, loudness, and location of soundis interpretedImage Upload 5
  7. Auditory association area (temporal lobe)
    permits what we “hear.” past sounds are also stored hereImage Upload 6
  8. Primary olfactory cortex (temporal lobe)
    Smell impulses are sent here
  9. Olfactory association cortex (temporal lobe)
    conscious awareness of odors/interpretationImage Upload 7
  10. Primary gustatory area (temporal lobe)
    Interprets tasteImage Upload 8
  11. Wernicke’s area (temporal lobe)
    arranges vocabulary into meaningful speechImage Upload 9
  12. Premotor cortex (frontal lobe)
    “Executive decision area” Decides whether or not to do something, if so compiles the plan for muscle contractionsImage Upload 10
  13. Prefrontal cortex (frontal lobe)
    Controls group muscle contractionImage Upload 11
  14. Primary motor cortex (pre-central gyrus)
    Allow us to control voluntary movements of our skeletal musclesImage Upload 12
  15. Broca’s area (frontal lobe)
    Controls motor speech function. Coordinates lips, tongue, and cheeks for speechImage Upload 13
