5 Matching questions

  1. desynchronization
  2. after a length period of sleep deprivation, when you finally go back to sleep, the subject's first night of sleep contains a much higher proportion of _____ waves.
  3. REM deprivation studies show that
  4. dreaming occurs during ____ sleep.
  5. Muscle tone changes
  1. a REM sleep may be regulated separately from the amount of slow wave sleep (because it rebounded after being deprived) and that REM sleep may serve a special function.
  2. b Delta waves. Slow waves
  3. c REM
  4. d when two different cycles (core body temperature, and sleep-wake cycles become desynchronized). This suggests that there are more than one circadian timing mechanism, and that sleep is not casually related to decreases in body temperature that normally correlates with it.
  5. e When a sleeper has come back down to one from 4, and they are at stage 1 again, they have a loss of muscle tone in the muscles of the body core.

5 Multiple choice questions

  1. that REM is the default state of sleep. If your body needs to perform any other function, than it switches-out to NREM, but once everything is take care of, you switch back to the default state of sleep: REM.
  2. no, they only can entrain the timing of it. But in an controlled environment with constant light and stuff, people still go through periods of wakefulness and sleep.
  3. (a precursor of serotonin) doesn't appear to have any therapeutic benefit in helping people sleep with insomnia.
  4. They block REM, but people are just fine. so it makes you question the need for REM sleep...
  5. because sleep becomes more efficient (more REM) in people who need it because they have been sleep deprived, it means that conventional sleep-deprivation studies are virtually useless for discovering how much sleep people really need.

5 True/False questions

  1. effects of sleep deprivationwhen two different cycles (core body temperature, and sleep-wake cycles become desynchronized). This suggests that there are more than one circadian timing mechanism, and that sleep is not casually related to decreases in body temperature that normally correlates with it.

          

  2. why sleep?2-3 second long periods of sleep--can even happen standing up. Usually happens while sleep deprived.

          

  3. ________ sleep appears to play the major recuperative role.According to Pinel, only 5.5 hours.

          

  4. environmental cues that can entrain circadian rhythms are called ______.thought to be responsible for maintaining wakefulness. High levels = wakefulness. Low levels = sleepiness.

          

  5. micro-sleeps2-3 second long periods of sleep--can even happen standing up. Usually happens while sleep deprived.
