Interesting facts about the brain

Does big brain make you smarter? The blind hear better hearing ordinary people? There are many surprising secrets about the human brain that we are not yet aware of.

Interesting things about the human brain you may not know

Fact: Watching a photo is harder than playing chess

When computer scientists try to write a program that simulates human ability, they find it quite easy to get computers to follow logic and do complex calculations, similar to moves - but very difficult to make the computer understand what it is seeing in a picture.

The best computer program today can beat a grandmaster, but any baby will beat the top software in exploring the visual world.

The cause stems from the difficulty in recognizing individual objects . You can only feel this ambiguity when you look at something that you mistakenly think - like a rock in the middle of the road that suddenly turns out to be a cat.

Mistake: You only use about 10% of the brain

In fact, every day you make full use of your brain. The truth is that even the simplest tasks create activity in the brain.

Truth: Yawning wakes up the brain

We often associate yawning with sleepiness and boredom, but the reality of that action helps awaken us. It will expand the windpipe, bringing air into the lungs and oxygen into the blood, helping us to be more alert.

Yawning also spreads. No one knows why, but it may be an advantage to help each other communicate to be alert.

Mistake: The blind heard better

In tests, blind people do not detect weak sounds better than others. But blind people have better memory . Since they cannot rely on images to identify things, they must keep in mind constantly, so honing more space-saving abilities.

They also perform better language exercises, including understanding the meaning of sentences, indicating the source of the sound - a way to help them determine the location of the object.

Fact: Video games help you be more flexible

The modern world is full of relentless activities - messages, emails, video games, and it all seems to happen simultaneously. If you are over 30 years old, you may wonder why children are not suffocated by all these activities. But their brains have simply been trained to deal with that. Extensive multitasking activities will increase the ability of people to pay attention to many things at the same time.

One of the sources of this type of activity is the video game, in which the goal is to shoot as many enemies as possible before they shoot us down. Games of this type require players to allocate attention throughout the screen, and quickly detect and respond to events.

So it is not a bad thing for children to play electronic games

Mistake: Big brains make you smarter

Brain size does not reflect your intelligence. After all, Einstein's brain was no bigger than a normal person's brain.

However, research shows that our intelligence depends on when synapses are formed . These synapses develop and shrink throughout childhood and puberty, and the model of this process will affect intelligence.

Fact: Exercise helps the brain stay healthy

Forget the word games or sudoku, new physical activity keeps your brain healthy as you get older.

As your circulatory system ages, the blood supply to nerve cells is reduced, causing them to lack the necessary oxygen and glucose. Regular exercise increases the number of small blood vessels in the brain, thereby boosting the supply of oxygen and glucose to neurons.

In fact, exercise is the only thing useful to maintain cognitive ability when you get older. Those who have been athletes throughout their youth will have better mental abilities than those who are less active in the same age.

To be effective, exercise every 30 minutes , several times a week, but not necessarily strong.

Fact: Your brain has a capacity not equal to a refrigerator light bulb

The message between brain cells and the entire body is transmitted by electricity - but only in very small amounts. The human brain only uses about 12 watts of electricity , less than energy to light a light bulb behind the refrigerator.

Although the brain is quite effective, it is also very wasteful. Only accounts for 3% of body weight, but consumes 1/6 of the entire body's energy.

Mistake: Listening to Mozart music makes children smarter

There is no scientific evidence for this.

The mistake began in 1993, when Nature science magazine reported that listening to 10 minutes of a Mozart sonata would boost the ability of college students to take a thinking test.

The idea was repeated a few years later by a US governor. He gave parliament members a listen to Beethoven's Ode To Joy and asked for $ 100,000 to send classical music to new born mothers in the state.

The Mozart effect comes from that - despite the fact that no one has verified it on children. But the idea of classical music makes children smarter has been repeated in magazines, books, documents and stories about Mozart music effects for students replaced by babies.

But even if classical music does not improve children's minds, it also encourages them to play music. Children who learn a musical instrument will be able to think space better.

Fact: The silly melodies are so unforgettable

There is nothing more annoying than a certain verse repeating in your mind again and again. The cause comes from the ability to remember the sequence of events of the brain.

We need to keep in mind a series of daily events, from morning coffee to the road to go to work.

This ability to remember makes everyday life happen smoothly. And when you think about a song melody, your brain automatically attaches it to that sequence. This makes you always remember the verse and continue to enhance memorization. It is this cycle that helps you keep memories.

One way to eliminate this model is to think of another event to replace the old one. So find another song and hope that it will be more pleasant than that annoying melody.

Reality: You cannot tickle yourself

The reason is because your brain focuses on what's happening in the outside world, to prevent important signals from sinking in the mess of your own actions. For example, you will not notice the contact of socks on your feet, but you notice a pat on your shoulder. People will not be able to feel the sensation of tickling caused by their brain knowing that you do it yourself.
