Interesting Facts of Brain 

1. About 85% of the total weight of a human brain is the Cerebrum—the region of the brain responsible for motor control. More than 8,000 autopsies revealed the average weight of the male brain is 1,336 grams and the female brain is 1,198 grams. As we age the weight of the brain decreases.

2. Humans have the largest brain in terms of size ratio when compared to other creatures in the world. Elephants are considered as having the largest brain, which is partially true. If the ratio of the whole body and the size of the brain are compared it is only 0.15% in the elephant case; however, it is 2% in the case of humans.

3. The adult human brain weighs nearly 1.5 kilograms (3 pounds). While it makes up only 2% of a person’s weight, it consumes around 20-30% of the total energy.  That is why glucose is drained so fast in the brain.

4. A brain produces almost enough energy to light a bulb. On an average, a brain produces up to 30 – 35 watts at the time of awakening. The main energy source of the most energy hungry organ is glucose.

5. A brain uses approximately 20% of whole blood and oxygen flowing through the body to perform actions like yawning and intelligence. A person can lose consciousness if the brain is deprived of oxygen for around 7-9 seconds.
