Interesting Facts about Brain

Humans have the most complex brain of any animal on earth.

1) Your brain is about 1300-1400 cubic centimeters in volume, about the size of a cantaloupe and wrinkled like a walnut.

2) Your brain contains about 100 billion neurons which is about 16 times the number of people on Earth. Each of them links to as many as 10,000 other neurons. This huge number of connections opens the way to massive parallel processing within the brain.

3) Your brain is full of nerve cells, but it has no pain receptors. Doctors can operate on your brain while you're awake and you won't feel a thing.

4) Your brain is about 75% water.

5) 750ml of blood pumps through your brain every minute which is 15-20% of blood flow from the heart.

6) The brain feels like a ripe avocado and looks pink because of the blood flowing through it.

7) Your brain is divided into two sides. The left side of your brain controls the right side of your body; and, the right side of your brain controls the left side of your body.

8) Your cerebral cortex is about as thick as a tongue depressor. It grows thicker as you learn and use it.

9) The neocortex (a section of the brain involved with language and consciousness) accounts for about 76% of the mass of the human brain. Human neocortex is much larger than any animals. It gives humans unique mental capacities although its brain architecture is similar to that of more primitive species.

10) Your brain is the most energy-consuming part of your body. The brain represents only 2% of the body weight, but it uses up to 20 percent of the body’s energy production. The energy is used for cell-health maintenance and to fuel electrical impulses that neurons employ to communicate with one another.

11) Your brain generates 25 watts of power while you're awake---enough to illuminate a light bulb.

12) Neurons multiply at a rate 250,000 neurons per minute during early pregnancy.

13) A newborn baby's brain grows almost 3 times in course of first year. When you are born, your brain weighs about a pound. But by age 6, it weighs three pounds. What happens? Learning to stand, talk, and walk creates a web of connections in your head—two pounds worth!

14) Studies have shown that children who are breast fed display IQ's up to 10 points higher by the age of three.

15) Humans do not use only 10% or less of their brain. This is a common misconception. Even though many mysteries of brain function persist, every part of the brain has a known function.

16) Most strange fact, Our brain often fools us. It often perceives things differently from the reality. There are various illusions present, which will justify this statement.

17) It is estimated that the human brain has a raw computational power between 1013 and 1016 operations per second. It is far more that 1 million times the number of people on Earth. If 100 million MIPS (Million Instructions Per second) could do the job of the human brain's 100 billion neurons, then one neuron is worth about 1/1,000 MIPS, i.e., 1,000 instructions per second. If you think that your brain is slower than super computers, you are definitely wrong. Because you don't know the processing speed it takes for what you see, what you hear, what you think, what you speak, what you feel, all done simultaneously.
