Brain Facts – Intriguing Things You Should Know About the Human Brain

According to renowned neurosurgeon, Ben Carson, “The brain is a miracle”. The human brain has never stopped amazing and baffling individuals all through the ages. Various scientists and researchers have devoted their entire lives to learning and studying how the brain works.

Here are some facts about your brain:

Physical Attributes

  • The weight of your brain is about 3 pounds.
  • Your skin weighs twice as much as your brain.
  • Your brain is made up of about 75 percent water.
  • Your brain consists of about 100 billion neurons.
  • There are anywhere from 1,000 to 10,000 synapses for each neuron.
  • There are no pain receptors in your brain, so your brain can feel no pain.
  • There are 100,000 miles of blood vessels in your brain.
  • Your brain is the fattest organ in your body and may consist of at least 60 percent fat.

The Developing Brain

  • At birth, your brain was almost the same size as an adult brain and contained most of the brain cells for your whole life.
  • A newborn baby’s brain grows about three times its size in the first year.
  • Humans continue to make new neurons throughout life in response to mental activity.
  • The first sense to develop while in utero 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.

Brain Function

  • Your brain uses 20 percent of the total oxygen in your body.
  • If your brain loses blood for 8 to 10 seconds, you will lose consciousness.
  • While awake, your brain generates between 10 and 23 watts of power — or enough energy to power a light bulb.
  • The old adage of humans only using 10% of their brain is not true. Every part of the brain has a known function.
  • 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.
  • A study of 1 million students in New York showed that students who ate lunches that did not include artificial flavors, preservatives, and dyes did 14 percent better on IQ tests than students who ate lunches with these additives.

Psychology of Your Brain

You can’t tickle yourself because your brain distinguishes between unexpected external touch and your own touch(the only place you can tickle yourself is your upper part of your mouth).

There is a class of people known as super tasters who not only have more taste buds on their tongue, but whose brain is more sensitive to the tastes of foods and drinks. In fact, they can detect some flavors that others cannot.

The connection between body and mind is a strong one. One estimate is that between 50-70 percent of visits to the doctor for physical ailments are attributed to psychological factors.


  • Every single time you recall a memory or have a new thought, you are creating a new connection in your brain.
  • Memories triggered by scent have a stronger emotional connection, and therefore appear more intense than other memory triggers.
  • While you sleep at night may be the best time for your brain to consolidate all your memories from the day. Lack of sleep could actually hurt your ability to create new memories.

Sleep and Dreams

  • Most people dream about 1-2 hours a night and have an average of 4-7 dreams each night.
  • Studies show that brain waves are more active while dreaming than when you are awake.
  • Some people (about 12 percent) dream only in black and white while others dream in color.
  • While you sleep, your body produces a hormone that may prevent you from acting out your dreams, leaving you virtually paralyzed.
