10. How can we With an EEG: Electroencephalography.
study Sleep?
11. What are the • Stage #1 (2-5 min): you're easy to wake up. Going from alpha to theta waves.
stages of sleep? Twitches happen here.
• Stage #2 (20 min): theta waves, random neurons are firing. Sleep-talking hap-
pens here.
• Stage #3 (30 min): going from theta to delta waves. Heart rate, respiration and
brain slow down. Bodily movements. Sleep-walking happens here.
• Stage #4 (20-30 min): delta waves. Slowest and deepest sleep.
-R.E.M or Rapid Eye Movement (10 min): Paradoxical Sleep. You see alpha, theta
and beta waves. After each cycle, the R.E.M times increase.

the information collected during the day.
c) The "Evolutionary/Circadian" view: we sleep in order to keep safe when we can
least defend ourselves, that is at night.

Sleep Disorders? • Other: sleepwalking, sleep apnea, narcolepsy, night terrors (happen in Stage #4).
