  • Amazingly, there are no nerves in the human brain. No other human organ can claim the same. It cannot feel any pain.
  • The human brain consumes a fifth of the energy generated by the human body. That is the largest portion of energy to any body part. What’s unbelievable about this is that the brain is only 2 percent of a person’s body weight. This energy can even light up a light bulb.
  • There are approximately 100 billion neurons in the brain. That’s over 15 times the human population of the world.
  • Around 60 percent of the brain is fat, which is why it the fattest (or fattiest) human organ.
  • Three-fourths of human brain mass is made up of water.
  • The neocortex makes up over 75 percent of the human brain. This part is where language and consciousness come from.
  • When the heart pumps blood, around 750ml of it heads towards the brain every 60 seconds.
