  11. What sleep stage lasts 1-7 minutes that includes; Theta waves, slow and slow rolling eye movement ?
    Stage 1
  12. What sleep stage includes the presence of K complexes and sleep spindles against a background of mixed frequencies predominantly in the Theta range ?

    K Complex (1-3 per minute)
  14. What is a brain wave of about 12-14 cps lasting .5 - 1.5 seconds and often waxes and wanes in amplitude ?
    Sleep Spindle (3-8 per minute)
  15. What stages are known as Slow-wave sleep ?
    Stages 3-4
  16. Where is there no eye movements and while muscle tensions is still present, the levels are low ?
    Slow-wave Sleep
  17. What stage is where the body restores itself and increases growth hormones in children ?
    Non-REM sleep (Stages 1-4)
  18. What REM sleep includes muscle twitching with bursts of eye movements ?
    Phasic REM sleep
  19. What REM sleep includes few or no eye movements and muscle twitches ?
    Tonic REM sleep
  20. What hormone is secreted by the tutelary glands and allow an individual to just lie awake in complete darkness and still get the benefits of sleep ?
    Prolactin
  21. What term refers to the time that it takes to fall asleep ?
    Sleep Latency
  22. What term refers to the ratio of actual time spent asleep to time spent in bed ?
    Sleep Efficiency
  23. What term refers to the overall balance of sleep and wakefulness during a night of sleep ?
    Sleep Continuity
  24. What drug can inhibit movement during sleep ?
    Fluoxetine
  25. Can people still dream in non-REM sleep ?
    Yes, but because less brain waves we forget the dreams due to the feeling of grogginess
  26. Who conducted the study where participates awakened from REM sleep 74% reported detailed dreams involving visual imagery, and when awakened from Non-REM sleep 9% reported dreams at all ?
    Aserinsky
  27. What is Soliloquy ?
    When you are talking when you are sleeping
  28. Is it true that REM sleep dream reports were significantly longer, had more characters other than oneself as well as having more undefined characters such as groups of people, and contained more emotion than SWS dream reports ?
    Yes
  29. What is considered to be core sleep ?
    First three stages
  30. During NREM sleep noradrenalin and serotonin decrease allowing what neurotransmitter to become active ?
    Acetylcholine
  31. What drug potentiates the effects of noradrenalin and serotonin through a number of mechanisms ?
    Amphetamine
  32. What drug increases sleep latency, worsens sleep continuity, increases body movements, reduces the total amount of sleep and decreases SWS and REM sleep ?
    Alcohol
  33. Which drug slows down the re uptake of noradrenalin, and reduces total amount of sleep ?
    Cocaine

    Opioid
  35. What sleeping disorder includes symptoms of; irresistible sleep attacks, cataplectic attacks, and sleep paralysis
    Narcolepsy
  36. What symptom includes an individual falling asleep at anytime, anywhere for a time frame of a few minutes to more than an hour ?
    Sleep attacks
  37. What symptom includes bilateral muscle weakness that can occur spontaneously or can be brought on by emotions such as laughter, anger, stress, fatigue, or heavy meals
    Cataplectic attack
  38. What symptom includes partial or total paralysis lasting a few seconds or minutes that occurs during transitions between sleep and wakefulness ?
    Sleep paralysis
  39. What is the term where an individual visualizes vivid images while falling asleep ?
    Hypnagogic
  40. What is the term where an individual visualizes vivid images while waking up ?
    Hypnopompic
  41. What is the term that describes experiences that appear to occur outside of one's body, including seeing one's body lying some distance below oneself ?
    Exosomatic
  42. What disorder includes an person falling asleep, her muscles relax, and the upper airway becomes blocked so that she cannot breathe. While she is not breathing, the level of carbon dioxide in the blood increases until the increase is registered by the nervous system, which wakes the person up enough to restore muscle tension, thereby opening the upper airway and allowing her to breathe ?
