An adult human brain weight about 3 pounds about 75% of which is made up of water. The brain uses 20% of total oxygen in blood, if it does not get the oxygen for five to six minutes, it would not survive. There are 100 billion neurons present in the brain. Neurons works as the information carriers they move information from one place to another producing enough electrical signal to power a light bulb.
Some people believe that we use only 10% of our brain and if we can use remaining the 90% brain we would be able to do superhuman activities. Well it is just a myth. Scientists who study brain activities found that we use virtually every part of the brain and most of it is active all most all the time. Some parts of the brain might be working very harder then other but we utilize almost all of the brain.
