Ever wonder how we can react too fast for things like finger cut or burns and so on..?? Its because the nerve impulse to and from brain travels at the speed of 170 mph (273.6 km/h). It brings a very fast reactions to the affected body parts at super speed.
The brain is made up of only 2% of your entire body mass, but it consumes 20% of oxygen supply to our body, more than any other organ in the body. Hence, when a person suffers from oxygen deprivations, they may damage their brain.
When you became passive (sleep), your brain will be active. The brain is much more active at night during the day. It means that lying on the bed takes up more brain power than undergoing complicated task, calculations, movement around and so on. Scientists yet knows why is this so, but this might be a factor why we could dream while we sleep.
Our brain cell is capable of keeping 5 times as much information as Encyclopedia Britannica have.The storage capacity is said to be 1,000 terabytes in electronis terms. It means that our brain's memory power is pretty impressive.
Our brain generates energy that could light up a light bulb even while sleeping. Brain operates on the same amount of power as much as 10W light bulb. It means, the cartoon image of light bulb over the head when thought occurs isn't a joke.
Not all neurons are the same, Well, information travels at different speeds within different types of neurons. There are impulse from a neuron which travels as slow as 1/2 metres per seconds or also as fast as 130 metres per seconds.
When we are in situations of making a decision or in examination hall, we are told to drink water. This is because 80% of brain is made up of water. It isn't firm but soft, squishy and jelly-like organ. It is because of higher blood and water content of tissues. So, next time, drink water to make your brain active and productive.
The brain cannot feel the pain although it is the center of pain. It doesn't mean one cannot have headache, they can because the brain is surrounded by plenty of nerves, tissues, and blood vessels where they have loads of pain receptors can cause headache.
Higher the I.Q. that a person have, the more they dream. But don't feel that you mentally lacking if you can't recall your dreams. The average length of a dream is around 2-4 seconds and its pretty impossible to register them. Talking about I.Q. , scientists found that its better for someone to talk to themselves. It seems that the more you talk to yourself, the more I.Q. you will have.
