7. 
    What does an Electroencephalogram (EEG) do? 
    • It measures waves of electrical brain activity.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 



 
 
 
 
 
 

8.
What is Rapid Eye Movement (REM) Sleep like? 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 



 
 
 
 
 

8.
What is Rapid Eye Movement (REM) Sleep like? 
  • Brain waves speed up: look like active wakefulness Beta waves
  • Body is paralyzed except for eyes, which move back and forth rapidly.
  • This is when we dream.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 



 
 
 
 
 

9.
What is the Adaptive or Circadian Function of Sleep?

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 



 
 
 
 
 

9.
What is the Adaptive or Circadian Function of Sleep? 
  • Sleep keeps us quiet at night while we’re vulnerable because it’s dark.
  • Millions of years ago we were vulnerable at night.
  • People who went outside at night got eaten by lions.
  • People who stayed quiet at night survived.
  • We learned to stay quiet at night.

    • To keep from getting too bored we go into a daze - that's why we sleep.
