Very few things intrigue people as much as the human brain. How come people can do the things they do? What compels people to feel the way they do? How come some people are born with disabilities such as autism? And how can these disabilities be cured? Here are some of the facts about the human brain that people may not know.
- 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.
