WCUI Human Brain Discussion

Category: Nursing


Consider the following facts about the human brain:

  • The adult brain uses 20% of the body’s energy but accounts for only about 2% of the body’s total weight (averaging around 3 pounds).
  • When a person is awake, his or her brain generates 25 watts of power; this is enough to power a lightbulb.
  • The left side of the brain controls the right side of the body, while the right side of the brain controls the left side of the body. Relate this to a stroke on the right side of the brain. Ask students what could be affected on the left side of the body.
  • The average human brain contains 100 billion neurons; the rate of neuron growth during development of a fetus is 250,000 neurons per minute. This is a good opportunity to bring up the effects of alcohol on the developing fetus (fetal alcohol syndrome).
  • There are more neurons in the human brain than there are stars in the Milky Way.
