  1. There are approximately 100 billion nerve cells in the human brain that communicate information to other parts of the body.
  2. There are over 100,000 miles of blood vessels in the brain.
  3. The right side of your brain interacts predominantly with the left side of your body and vice versa. Science is still in pursuit of the reason for this opposite function.
  4. The brain weighs over 3 pounds, and makes up just about 2% of your bodyweight.
  5. While many large animals have bigger brains, humans have the largest brains per body size of any type of animal.
  6. The skull, which acts as the brain’s protective casing, is comprised of more than 20 different small bones.
  7. The brain is made up of over 75% water.
  8. When deprived of oxygen, the brain will begin to die after about 5 minutes, resulting in brain damage.
  9. Humans have, on average, 70,000 different thoughts daily.
  10. Even though the brain takes up little space in the body, it utilizes over 20% of your body’s blood and oxygen.
  11. Your brain processes new information at the whopping speed of 268 miles an hour!

  13. A baby’s brain triples its size in the first year of life.
  14. When you blink, your brain amazingly keeps things illuminated so your world doesn’t go dark 20,000 times daily.
  15. Ever feel like a thought, name or question is on the tip of your tongue? Well this tip-of-the-tongue syndrome has a medical name: lethologica.
