Shocking facts about the human brain

The brain is the most complex and mysterious organ in the human body. Scientists have had many studies on them but the brain still has many mysteries with us. But from the past there was a lot of information, false assumptions about this agency.

1. The brain is gray

You may have seen brains that are white, gray or yellow and think the brain has that color. In fact, the brain is white, black and red. However, this legend is somewhat true because there are also gray parts on the brain. These are often places that contain many types of cells, like nerve cells.

2. Listening to Mozart music makes the brain smarter

Many people have long assumed that listening to Mozart music can help develop children's cognitive abilities. But according to a recent study by scientists at the University of California, Mozart music doesn't really make us smarter. In fact, it only helps us improve our ability to perform some temporary and spatially related tasks.

3. When learning something new, you have new wrinkles on your brain

When in the first weeks of pregnancy, our brain has almost no wrinkles. Along with the development of pregnancy, the brain gradually improves. By the 40th week, the brain was almost shaped. So the brain can't have new wrinkles when we learn new things.

4. You can learn from subconscious messages

The subconscious message is the word given by American market researcher James Vicary in 1957. It is attached to images or sounds, which work deeply into awareness and affect their behavior. me. However, tests conducted later confirmed that subconscious messages do not have any effect on us.

5. Human brain is the biggest brain

The right species is the smartest animal in the world, but that doesn't mean the world's largest human brain. The adult's brain weighs only 1,361kg, while the brain of sperm whale weighs 7.8kg. While actually sperm whales are smarter than other mammals, if compared to us, it is a lame comparison. Intelligence depends on many factors, not on the weight of the brain.

6. The brain is still active after being cut down

Many people believe that after being cut down, the brain can still function for a short time (tens of seconds). However, the fact is that immediately after being cut off from the heart, the brain falls into a coma and begins to die. Eyelid movements that many people think are signs of brain activity are actually reflexes of the muscle.

7. Brain damage is permanent

Many people believe that the damage that the brain endures will be eternal. This is not entirely true. By having some brain damage can be partially recovered after injury. When nerves are damaged or die, they cannot grow back, but the connections between nerves can be restored to create new connections between nerves.

8. Using opium, your brain will have holes

Many people believe that if you use addictive substances, your memory will be reduced. If you use more addictive drugs like cocaine or ecstasy, you may have some holes in your brain. This is absolutely not true. You only get holes in your brain if you are physically damaged.

9. Alcoholic kills brain cells

Many studies have shown that alcohol has a direct effect on your brain. But to kill brain cells is not. Alcohol can cause messages not to travel between nerve cells. Although they did not die, the cells had to change the way they linked together.

10. People use only 10%

Many people believe that we only use 10% of our brain in activity, but this idea is not true. The brain is a collection of many types of cells, often used. It is not necessary to use it at the same time, for example when we walk, the part of the brain that is responsible for controlling the foot will be more active than other parts. There are no parts of the brain that we don't use. Although the brain only accounts for 3% of the body's weight, it uses up to 20% of its energy to work properly. We can be paralyzed if there is any damage to the brain, no matter where it is, and it is always active, no matter what you do.

11. Speed ​​of nerve impulse transmission

The nerve impulses coming and going from the brain spread at a speed of 270 km / h, which is equivalent to the speed of a large-capacity supercar. Have you ever wondered how your body responds immediately to the effects around you or why when your feet stumble into an object, does the pain feel instantly? This is due to the super-fast movement of nerve impulses from the brain to every part of the body and vice versa.

12. Ability to store information

The brain can store five times the information of the Britannica Encyclopedia. Scientists have not yet determined the exact capacity of the brain. They think that, in terms of electronic storage units, the brain has a capacity of 3 to 1,000 terabytes. The UK National Archives Center stores data for more than 900 years of history, but only about 70 terabytes. That number shows us the tremendous data storage capacity of the brain.

13. The time when the brain is most active

The brain works more at night than during the day. Many people believe that moving, calculating, thinking, interacting during the day will make the brain work much more tired than the night time the body rests in bed. The truth is quite the opposite. When you rest, your brain starts working. Scientists still cannot explain this phenomenon. However, they argue that thanks to these brain code activities you can experience beautiful dreams.

14. Smart people dream a lot

The higher the IQ is, the more likely it will be when you sleep. However, you should not feel confident if you cannot remember the happenings in your dreams. Most people cannot remember all the events in their dreams because they last only 2-3 seconds, too short for the brain to record.

15. Speed ​​of transmission of different information

Different neurons transmit information at different speeds. Many neurons exist in the brain. Some have only 0.5 m / s propagation speed while others transmit new information at super speed of 120 m / s.

16. The brain does not feel pain

As the center to receive pain when you cut into your hands or burns, but the brain itself does not feel pain when it hurts because there is no pain receptor. Terrible headaches occur due to the numerous surrounding tissues, nerves and blood vessels that receive pain from the damaged sites.

17. The brain has many senses

The brain has more than the usual senses. For example, the senses of sensing pain, senses sensing the position of the body, senses sensing balance, height, temperature, sense of time, etc.

18. We have about 100 billion brain cells

In 2009, scientists conducted experiments and found that humans only averaged about 86 billion brain cells , compared with 100 billion previously identified. Although the difference seems to be small, 14 billion is the number of menstrual cells of African apes. For a more intuitive comparison, imagine 1 million seconds is 12 days, and 1 billion seconds equals 31 years, the 14 billion figure is not small at all.

19. The memory loss when aging is due to brain degeneration

Only 3% of people aged 65-75 are affected, while 85 years of age have nearly 50% of dementia. The disease is a common health problem in developed countries, which causes shrinkage, especially in the hippocampus information center. Middle-aged obesity is also a risk factor for this disease.

20. Weight of the brain

Our brain is only heavier than 1400 grams and the brain of a man is 10% larger than a woman's brain. But this does not mean that men are more likely or smarter, women's brains have more neurons and joints, and are more effective than men 's brains. Moreover, women tend to handle things in the left hemisphere more emotionally, while men concentrate in the right hemisphere of the brain, which is 'more logical'. In addition, an area called the "straight brain roll" of the brain - the area responsible for nourishment, feminine characteristics - accounts for a greater proportion in women.

21. An important part of brain function is personality

This part may be due to genetics or because we are affected by the childhood environment. There are five distinct characteristics of personality division in the brain, these characteristics also play a decisive role for human personality: open, honest, extroverted, pleasant and impatient. Open-minded people seem less sad, honest honest people can be loved by everyone but get more pain in life. An extrovert is more fun but tends to be less alert. The easy-going people are warm, but too trusting people and the ability to judge problems is also poor.
