Across
  1. 2. The brain’s ability to change, especially during childhood, by reorganizing after damage or experience.
  2. 4. A brain area of the left temporal lobe involved in language comprehension & expression.
  3. 5. Techniques using magnetic fields & radio waves to produce computer-generated images that distinguish among substances; this allows us to see structures within the brain as well as track blood flow to determine what parts of the brain are more active.
  4. 6. The lobe of the cerebral cortex lying at the back of the head; it includes the primary visual processing areas of the brain.
  5. 11. A neural center located in the limbic system that wraps around the back of the thalamus; it helps process new memories for permanent storage.
  6. 13. A nerve network in the brainstem that plays an important role in controlling wakefulness & arousal.
  7. 16. A series of X-ray photographs taken from different angles & combined by computer into a composite representation of a slice through the body.
  8. 18. A ring of structures at the border of the brainstem & cerebral cortex & it includes the hypothalamus, the hippocampus, & the amygdala.
  9. 20. The lobe of the cerebral cortex lying just behind the forehead that is involved in planning & judgment; it includes the motor cortex.
  10. 21. _______cortex - A strip of brain tissue at the rear of the frontal lobes that controls voluntary movements.
  11. 23. The “little brain” attached to the rear of the brainstem; it helps coordinate voluntary movements & balance.
  12. 24. The brain’s sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex.
  13. 25. Located at the base of the brainstem, it controls basic life-support functions like heartbeat & breathing.
Down
  1. 1. A visual display of brain activity.
  2. 3. The long crevice that divides the cerebral cortex into the left & right hemispheres.
  3. 7. An almond-shaped neural cluster in the limbic system that controls emotional responses, such as fear & anger.
  4. 8. An amplified recording of the waves of electrical activity that sweep across the brain’s surface; these waves, measured by electrodes placed on the scalp, are helpful in evaluating brain function.
  5. 9. A neural structure lying below the thalamus; it helps regulate many of the body’s maintenance activities, such as eating, drinking, & body temperature, & is linked to emotion.
  6. 10. The oldest part & central core of the brain; it begins where the spinal cord swells as it enters the skull & is responsible for automatic survival functions.
  7. 12. A brain area of the left frontal lobe that directs the muscle movements involved in speech.
  8. 14. The large band of neural tissue that connects the two brain hemispheres & allows them to communicate with each other.
  9. 15. A research technique in which one person is studied in depth in the hope of revealing universal principles.
  10. 17. _____cortex - A strip of brain tissue at the front of the parietal lobes that registers & processes body sensations.
  11. 19. The lobe of the cerebral cortex lying at the top of the head & toward the rear; it includes the somatosensory cortex & general association areas used for processing information.
  12. 21. Techniques using magnetic fields & radio waves to produce computer-generated images that distinguish among substances; this allows us to see structures within the brain
  13. 22. The lobe of the cerebral cortex lying roughly above the ears; it includes the auditory (hearing) areas of the brain.
