  1. Smooth electrical activity of 8-12 Hz recorded from the brain; generally associated with state of relaxation.
    Alpha activity
  2. Irregular electrical activity of 13-30 Hz recorded from the brain; generally associated with a state of arousal
    Beta activity
  3. EEG activity of 3.5-7.5 Hz that occurs intermittently during early stages of slow-wave sleep and REM sleep
    theta activity
  4. Regular, synchronous electrical activity of less than 4 Hz recorded from the brain; occurs during the deepest stages of slow wave sleep
    Delta activity
  5. The stage with the transition between wakefulness and sleep. Eye lids open and the eyes roll up and down.
    Stage One
  6. Short bursts of waves of 12-14 Hz that occur between two and five times a minute during stages 1-4 of Sleep
    Sleep spindles
  7. Sudden, sharp wave forms that are usually found only during stage 2 sleep. Occur at a rate of about one per minute but can also be triggered by noises
    K complexes
  8. This stage contains 20-50 percent delta activity
    Stage 3
  9. Stage that contains more than 50 percent delta activity
    Stage 4
  10. A period of desynchronized EEG activity during sleep, at which time dreaming and muscular paralysis occur. Also called paradoxical sleep.
    REM sleep
  11. A 90-minute cycle of waxing and waning alertness, controlled by a biological clock in the caudal brain stem; controls cycles of REM sleep and slow-wave sleep
    Basic rest-activity cycle
  12. Sleep characterized by synchronized EEG activity during its deeper stages.
    Slow-wave sleep
  13. If you deprive people of sleep, what type of sleep do they make up?
    People make up slow-wave sleep, as the cycles become longer. But they don't make up total sleep.
  14. A loss of slow wave sleep and decreased REM sleep. Can cause insomnia and damage to the thalmus.
    Fatal familial insomnia
  15. Infants engage in mostly what kind of sleep?
    REM sleep
  16. This sleep disorder affects 25% of the population. Can cause anxiety and depression.
    Insomnia
  17. A sleep disorder when breathing stops during sleep.
    Sleep apnea
  18. A sleep disorder where that has to do with the central nervous system's inability to control REM. You can begin REMing at any point during the day.
    Narcolepsy
  19. A part of narcolepsy where there is muscular paralysis but the person is awake. It is triggered by strong emotion or sudden movement.
    Cataplexy
  20. When a person is close to falling asleep or just woke up and cannot move.
    Sleep paralysis
  21. When a person dreams during sleep paralysis (sees people in the room)
    Hypnagogic hallucinations
  22. When there is no physical paralysis and people physically act out dreams.
    REM without atonia
  23. A slow wave sleep disorder that is very common in children and adolescence.
    Sleep walking
  24. A slow wave sleep disorder where a person goes from stage 4 to stage 1 in about 30 seconds. Shocks the nervous system
    Night terrors
  25. Sleep duration can depend onĀ 
    body size. The larger you are the longer you sleep
  26. Daily rhythmic changes in behavior and physiological processes.
    Circadian rhythms
  27. This is the part of the body that works with circadian rhythms. Part of the hypothalmus on top of the optic chiasm. This is our biological clock.
    Suprachiasmatic nucleus
  28. Attached to the dorsal tectum; produces melatonin and plays a role in seasonal rhythms.
    Pineal gland
