Show Answers:

  1. Cerebral Cortex
    • the intricate fabric of interconnected neural cells covering the cerebral hemispheres
    • the body's ultimate control and information processing center
  2. Frontal Lobes
    • portion of the cerebral cortex lying just behind the forehead
    • involved in speaking and muscle movements and in making plans and judgments
  3. Parietal Lobes
    • portion of the cerebral cortex lying at the top of the head and toward the rear
    • receives sensory input for touch and body position
  4. Occipital Lobes
    • Portion of the cerebral cortex lying at the back of the head
    • includes areas that receive information from the visual fields
  5. Temporal Lobes
    • portion of the cerebral cortex lying roughly above the ears
    • Includes the auditory areas, each receiving information primarily from the opposite ear
  6. Motor Cortex
    an area at the rear of the frontal lobes that controls voluntary movements
  7. Sensory Cortex
    area at the front of the parietal lobes that registers and processes body touch and movement sensationsAssociation areas
  8. Association Areas
    • Areas of the cerebral cortex that are not involved in primary motor or sensory functions
    • Involved in higher mental functions such as learning, remembering, thinking, and speaking
  9. Corpus Callosum
    the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
  10. Split Brain
    a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them
