SOME AMAZING FACTS ABOUT BRAIN

1. Human brain, which is only 3% of our body's mass, uses 20% of all the oxygen we breathe?
2. Our brain needs a continuous supply of oxygen. A 10-minute loss of oxygen will usually cause significant damage to brain cells.
3. Our brain uses a fifth of all our blood. This is because it needs it to keep up with the heavy metabolic demands of its neurons. It needs both the glucose and the oxygen.
4. Our brain feels no pain. There are no nerves that register pain within the brain itself. Due to this reason, neurosurgeons can probe the brain even when a patient is conscious. By doing this, they can use feedback from the patient to identify important regions, such as those used for speech, or visualization.
5. The cerebellum, sometimes called the "little brain," weighs about 150 grams (a little over five ounces). Found at the lower back side of brain, its function is to maintain posture, to walk, and to perform any coordinated movements. It may also play a role in your sense of smell. The human brain weighs an average of a little over three pounds, or 1.4 kilograms. Albert Einstein's brain may have been smaller than average, because he was smaller in body size than average. There is a general correlation between body size and the size of our brains.
6. An elephant's brain is about six times as large as a human brain. However, in relation to body size, humans have the largest brain of all the animals, averaging about 2% of body weight.
7. There are about 100,000 miles of blood vessels in the brain. If they were stretched out they could measure four times the circle of the earth.
8. An average sized brain has about 100 billion neurons.
9. Brain loses about 85,000 neurons each day. Fortunately, this is covered up due to the built-in redundancies and the fact that even after three years this loss adds up to less than 1% of the total.
10. Our brain continues to produce new neurons throughout our life. It does so in response to stimulation created by brain improving exercises, such as learning something new, a language, music, mathematical problem etc. The scientists agree that brain is a plastic muscle, which grows with exercise; in the same way our body muscles grow with exercise. In an experiment, it was discovered that the brains of laboratory rats showed physical changes when their environment was enriched with toys such as ladders and wheels, as well as other rats for company. Their brains were larger by 4% than those of another group of rats that were kept in ordinary environment.
11. Brain does not contain any fats in it like the rest of our body.
12. Brain consumes 40% of water consumed by the body. It may need about six glasses or one and a half liter of water per day. Therefore, on an average, we should drink at least 15 glasses of water to make our brain function to it optimum capacity. But if we drink higher quantity of water, it is even more useful, as it is helpful not only in flushing out the rejects from our body, but in further increasing brain efficiency.
13. A study has shown that the children of mothers, who frequently speak to them, learn about 300 more words by the age of 2 as compared to the children whose mothers rarely speak to them.
14. Our brain is generally more active and thinks more efficiently at night than during the day.
15. Our human brain generates more electric impulses in one day than all the telephones of world put together.
