47 Facts About The Brain


The human brain has amazed and baffled people throughout the ages of time. Many scientists and doctors have devoted their entire lives to learning how the brain works, but still we do not know everything about this incredible machine.

However, researches that have been carried out have proved the following interesting facts about the brain.

Facts about the Brain
  1. It is believed that we use about 7% of the brain, while Einstein used 10%.
  2. Our ability to store information in memory is huge; human brain cells can store five times more information than the Encyclopedia Britannica.
  3. The weight of the human brain is about 3 lbs.
  4. The brain is made up of about 75% water.
  5. There are no pain receptors in the brain, so the brain can feel no pain.
  6. While an elephant’s brain is physically larger than a human brain, the human brain is 2% of total body weight (compared to 0.15% of an elephant’s brain), meaning humans have the largest brain to body size.
  7. There are 100,000 miles of blood vessels in the brain.
  8. The human brain is the fattest organ in the body and may consists of at least 60% fat.
  9. Your brain consists of about 100 billion neurons.
  10. A newborn baby’s brain grows about three times its size in the first year.
  11. Your brain stops growing at the age of 18.
  12. Reading aloud and talking often to a young child promotes brain development.
  13. The capacity for such emotions as joy, happiness, fear, and shyness are already developed at birth. The specific type of nurturing a child receives, shapes how these emotions are developed.
  14. The first sense to develop  is the sense of touch. The lips and cheeks can experience touch at about 8 weeks and the rest of the body around 12 weeks.
  15. Your brain uses 20% of the total oxygen in your body.
  16. As with oxygen, your brain uses 20% of the blood circulating in your body.
  17. If your brain loses blood for 8 to 10 seconds, you will lose consciousness.
  18. Information can be processed as slowly as 0.5 meters/sec or as fast as 120 meters/sec (about 268 miles/hr).
  19. While awake, your brain generates between 10 and 23 watts of power–or enough energy to power a light bulb.
  20. It is thought that a yawn works to send more oxygen to the brain, therefore working to cool it down and wake it up.
  21. The neocortex makes up about 76% of the human brain and is responsible for language and consciousness. The human neocortex is much larger than in animals.
  22. The brain can live for 4 to 6 minutes without oxygen, and then it begins to die. No oxygen for 5 to 10 minutes will result in permanent brain damage.
  23. A study of one million students in New York showed that students who ate lunches that did not include artificial flavors, preservatives, and dyes did 14% better on IQ tests than students who ate lunches with these additives.
  24. You cannot tickle yourself because your brain can distinguish between unexpected external touch and your own touch.
  25. A study from Australia showed that children with imaginary playmates between the ages of 3 and 9 tended to be first-born children.
  26. Without any words, you may be able to determine if someone is in a good mood, is feeling sad, or is angry just by reading the face. 
  27. Scientists have discovered that men and women’s brains react differently to pain, which explains why they may perceive or discuss pain differently.
  28. Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.
  29. Some studies indicate that while some people are naturally more active, others are naturally more inactive, which may explain why getting out and exercising is more difficult for some.

  39. If you are awakened during a dream, you are much more likely to remember the dream than if you slept until a full night’s sleep.
  40. As those who invest in dream dictionaries can attest, dreams almost never represent what they actually are. The unconscious mind strives to make connections with concepts you will understand, so dreams are largely symbolic representations.
  41. Juggling has shown to change the brain in as little as seven days. The study indicates that learning new things helps the brain to change very quickly.
  42. Laughing is no simple task as it requires activity in five different areas of the brain.

  46. London taxi drivers are famous for knowing all the London streets by heart.  These drivers have a larger than normal hippocampus, especially the drivers who have been on the job longest. The study suggests that as people memorize more and more information, this part of their brain continues to grow.
