  2. 3. one of a class of drugs that results in profound alterations in sensory and perceptual experiences, often with vivid hallucinations
  3. 8. brain’s control of switching between sleep and wakefulness as well as coordinating this cycle with the outside world
  4. 14. second stage of sleep; the body goes into deep relaxation; characterized by the appearance of sleep spindles
  5. 15. clearing the mind in order to achieve a state of relaxed awareness and focus
  6. 16. consistent difficulty in falling or staying asleep for at least three nights a week over a month’s time
  7. 17. internal cycle of biological activity
  8. 20. one of a group of sleep disorders characterized by unwanted, disruptive motor activity and/or experiences during sleep
  9. 22. awareness of internal and external stimuli
  10. 24. variety of negative symptoms experienced when drug use is discontinued
  11. 26. first stage of sleep; transitional phase that occurs between wakefulness and sleep; the period during which a person drifts off to sleep
  12. 28. people become aware that they are dreaming and can control the dream’s content
  13. 29. sleep disorder in which the sleeper experiences a sense of panic and may scream or attempt to escape from the immediate environment
  14. 31. sleep disorder in which the sufferer has uncomfortable sensations in the legs when trying to fall asleep that are relieved by moving the legs
  15. 33. result of insufficient sleep on a chronic basis
  16. 34. sleep disorder defined by episodes during which breathing stops during sleep
  17. 35. device used to treat sleep apnea; includes a mask that fits over the sleeper’s nose and mouth, which is connected to a pump that pumps air into the person’s airways, forcing them to remain open
  18. 36. state of extreme self-focus and attention in which minimal attention is given to external stimuli
  19. 37. hidden meaning of a dream, per Sigmund Freud’s view of the function of dreams
  20. 38. storyline of events that occur during a dream, per Sigmund Freud’s view of the function of dreams

Down
  1. 1. characterized by high levels of sensory awareness, thought, and behavior
  2. 4. sleep-deprivedindividuals will experience shorter sleep latencies during subsequent opportunities for sleep
  3. 5. theoretical repository of information shared by all people across cultures, as described by Carl Jung
  4. 6. biological rhythm that occurs over approximately 24 hours
  5. 7. period of sleep characterized by brain waves very similar to those during wakefulness and by darting movements of the eyes under closed eyelids
  6. 8. infant (one year old or younger) with no apparent medical condition suddenly dies during sleep
  7. 9. sleep disorder in which the sufferer cannot resist falling to sleep at inopportune times
  8. 10. endocrine structure located inside the brain that releases melatonin

  10. 12. work work schedule that changes from early to late on a daily or weekly basis
  11. 13. sleep disorder with periods of interrupted breathing due to a disruption in signals sent from the brain that regulate breathing
  12. 18. sleep disorder defined by episodes when breathing stops during sleep as a result of blockage of the airway
  13. 19. tendency to maintain a balance, or optimal level, within a biological system
  14. 21. hormone secreted by the endocrine gland that serves as an important regulator of the sleep-wake cycle
  15. 23. lack of muscle tone or muscle weakness, and in some cases complete paralysis of the voluntary muscles
  16. 25. drug that tends to suppress central nervous system activity
  17. 27. rapid burst of high frequency brain waves during stage 2 sleep that may be important for learning and memory
  18. 30. state marked by relatively low levels of physical activity and reduced sensory awareness that is distinct from periods of rest that occur during wakefulness
  19. 32. period of sleep outside periods of rapid eye movement (REM) sleep
