10 strange things of the brain

The brain is one of the most complex parts of the human body, with many mysteries that can shock people.

Very fast speed of nerve impulse conduction

The nerve impulse coming and leaving the brain moves at about 273km / h, equivalent to the speed of a large-capacity sports car. Therefore, the human body reacts almost immediately to the surrounding effects.

The active energy is equivalent to a 10W light bulb

Images of light bulbs are often drawn on someone's head when they think of new ideas. The brain consumes energy as a small light bulb even when we are sleeping.

Ability to store large information

Human brain cells can store large amounts of information five times the Britannica Encyclopedia. Scientists have not yet determined the exact capacity of the brain, but it is estimated that between 3 and 1,000 terabytes. Meanwhile, the UK National Archives holds more than 900 years of data when it only accounts for 70 terabytes. This figure shows an impressive memory power of the brain.

High demand for oxygen

The brain only accounts for about 2% of body weight but consumes 20% of oxygen in the blood, more than any other organ. Therefore, it is very vulnerable to lack of oxygen.

The brain works more at night than during the day

Many people think that movement, complex calculations, work and human interaction during the day make the brain more active than at night. However, the reality is quite the opposite. The scientific community still cannot explain the phenomenon, but according to them, thanks to the activity of the brain during sleep, people can have beautiful dreams.

Smart people dream much

According to researchers, the higher the IQ, the more likely the dream will appear during sleep. However, the average length of dreams usually lasts only two to three seconds, too short for the brain to remember.

Neurons develop throughout human life

Although it does not function in the same manner as tissues in many other parts of the body, neurons are still capable of developing throughout human life. This finding opens up a whole new direction in brain research and brain-related diseases.

Speed ​​of transmission of information varies

Not all neurons in the body are the same. The rate of communication along these different neuron types may be slow (about 0.5m / s) or fast (120m / s).

The brain cannot feel pain itself

The brain is the center of pain when we cut or burn. However, the brain cannot feel pain when it is hurt because there is no receptor for pain.

80% of the brain is water

The brain is not a solid gray mass we often see on television. The brain tissue is very soft, pink, like jelly, because it contains a large amount of water and blood inside.
