8 interesting things you may not know about the brain

The human body is an incredibly complex and perfect system, a masterpiece that still holds great questions for doctors and researchers. Among the parts of the body, the brain is the most complex and confusing. There's a lot we don't know, but here are a few interesting facts that science has discovered.

Superfast nerve impulse conduction

The speed of nerve impulse conduction to and from the brain is more than 270km/h (meaning it takes less than 2% of a second to travel from the toe to the brain). Have you ever wondered how you can react so quickly to the impacts around you, or why your feet feel pain almost immediately after being stepped on? It's due to the super-fast movement of nerve impulses from your brain to the rest of your body and back, delivering the responsiveness of the latest high-speed sports cars.

Brain radiates energy

When the brain is active, it radiates the same amount of energy as a 10 watt light bulb. The promotional images depicting a light bulb glowing overhead when someone comes up with a big initiative actually depicts the process literally. And because the human brain is always active, it always generates energy like a small light bulb that never goes out, even when you're asleep.

Huge amount of memory

In your opinion, how much information can people “remember”? The answer may surprise you. Human brain cells can hold 5 times more information than Encyclopedia Britannica (the world's oldest English-language encyclopedia). Or any other encyclopedia you know. Scientists still do not have a unified number, but the storage capacity of the brain electronically can be up to 1,000 terabytes. Britain's National Archives, which contains more than 900 years of history, occupies only 70 terabytes, a comparison that makes brain memory truly impressive.

The brain "consumes" the most oxygen

Guess which muscles of the arms, calves or organs consume the most oxygen in the body? Actually, the answer is another answer. Your brain uses 20% of the oxygen that enters your bloodstream. The brain makes up only about 2% of our body mass, but consumes more oxygen than any other organ in the body, which makes it extremely vulnerable to oxygen deprivation. So, breathing deeply will keep the brain "happy in the ocean of oxygen".

The brain never sleeps

In your opinion, does the brain rest at night like humans? Logically, most of us think that the complex process of working, thinking, calculating, and general human interaction during working hours will consume a lot more brain power than lying down. in bed. In fact, the opposite is true. The brain is still active at night and more active than during the day. That is, the time when we go to sleep is the time when the brain is actively working. Scientists still can't explain this, but you can thank the hard and silent work of your brain while you sleep for all of our pleasant dreams.

The smarter the brain, the more dreams

Scientists say that the I.Q. The higher yours, the more dreams you have. This is true, but don't think that if you can't remember your dreams, you're showing signs of depression. Most of us don't remember much about our dreams and it's surprising to learn that the length of most dreams is usually very short, sometimes as little as 2-3 seconds.

The brain is 80% water

We are all used to television models and images of the solid, gray human brain. Actually not. 80% of the brain's weight is water. Live brain tissue is a wet, pink, and jelly-like mass thanks to its numerous blood vessels and high water content. So the next time you're feeling dehydrated drink something to quench your thirst.

The brain doesn't know pain

Many people, including you probably, still believe that the brain is the organ most susceptible to pain, so humans and many other animals have to hide their brains in a thick, sturdy skull. This is not entirely true. As noted above, the brain is in its soft, jelly-like form and is very vulnerable. But the brain itself cannot feel pain. So what makes you often find yourself having a headache like a hammer? The answer is: because the brain is surrounded by a multitude of tissues, the nerves and blood vessels contain many pain receptors and it is the pain center when your body is injured.
