Q
  • pulse quickens
  • breathing becomes fast and irregular
  • but our brainstem blocks messages from the motor cortex
  • after, we go back to stage 1
  • brain waves pick up speed and strengthens
  • 8-9 hours asleep–> last 4 hours will be spent more in this stage then first half
  • brain waves look more like someone awake based on brain activity

41
Q
  • equal opportunity drug

Q

Drugs that stimulate neural activity, causing speeded-up activity body functions and associated energy and mood changes
