Perhaps there is no more complex thing in the universe than the human brain. It regulates the work of all organs, is responsible for balance, allows you to think about various thoughts that come into it, and sometimes it is able to create beauty, and it turns into material objects. True, he is capable of terrible things, but still thanks to the Creator for the fact that we have him! Even if it doesn't work the same for everyone. In order to appreciate this most important device, which every person is equipped with from birth, it is enough to think a little about the simplest parameters to be quantified. For a long time they were collected by scientists: physicians, physicists, chemists and specialists in other exact sciences. Interestingly, they themselves used the subject of their research. Some of the facts are simply amazing.

Weight and power consumption

The brain consumes less energy than a refrigerator light bulb - only 12 watts, which is 17% of the total energy consumed by the human body.

Interesting facts about the human brain

The human brain is generally recognized as one of the most complex and at the same time the most advanced devices in the universe. Users of modern tablets and smartphones do not even think about the fact that in their head there is a storage device and a processor immeasurably more advanced than the most powerful computer.

1. In 2015, the fourth most powerful supercomputer in the world for 40 minutes to simulate only one second of human brain activity. According to the American inventor Raymond Kurzweil, only in 2023 personal computers will reach the processing power of the human brain.

2. The memory of the brain can accommodate the number of bytes expressed as a number with 8432 zeros. According to rough estimates of scientists, this is about 1000 terabytes. For comparison: the National British Archives, which stores the history of the last nine centuries, occupies only 70 terabytes.

3. There are 100,000 kilometers of blood vessels in our brain. The brain is also made up of one hundred billion neurons, as many as there are stars in our entire galaxy. The brain includes more than 100 trillion neural connections (synapses). New neural connections in the brain are formed every time you memorize something. That is, when you learn something new, the structure of the brain changes.

4. When waking up, the brain creates an electric field of 23 watts, which is enough to light a light bulb.

5. The brain only makes up 2% of the body, but it uses 17% of the body's energy and 20% of oxygen and blood.

6. The human brain is 75% water, and its consistency resembles tofu cheese. 60% of the human brain is fat. Therefore, for its proper functioning, it is very important to eat right and consume the “right fats” found in fish, olive oil, seeds and nuts.

7. Scientists believe that diet can cause the brain to “eat” itself. And the lack of oxygen in the brain for 5 minutes leads to irreversible damage.

8. A person cannot tickle himself. The fact is that the human brain is tuned to the perception of external stimuli, so as not to miss important signals in the stream of sensations caused by the actions of the person himself.

9. Forgetting is a natural process for the brain: removing unnecessary information helps the nervous system to maintain its flexibility. Alcohol does not affect memory - it's just that when a person gets drunk in the trash, the brain temporarily loses the ability to remember.

10. It only takes 6 minutes for the brain to react to alcohol. That is, intoxication begins 6 minutes after alcohol enters the body.

11. The world's largest brain donor is the monastic order of sister teachers in Mankato, Minnesota. The nuns of this order donated more than 700 brain units posthumously to science.

12. A person has more nerve cells at birth than in his entire subsequent life.

13. The brain is divided into two hemispheres. In this case, only the left or right hemisphere of the brain cannot work. They always work simultaneously, but the left hemisphere is responsible for rational, analytical thinking, and the right hemisphere is responsible for visual and mental thinking. They also work in opposition - your left heel is itchy, and the sensations are perceived by the right side of the brain. But there is one interesting fact, if half of the brain is turned off, then the person still survives.

14. Cruelty in the family has the same effect on the brain of a child as war does on the brain of a soldier. It has been scientifically proven that even a weak sense of power changes the way a person's brain works and reduces his ability to empathize.

15. Pathologist Thomas Harvey, who performed Albert's autopsy in 1955, stole his brain and stored it in formalin solution for about 20 years. In 1978, American journalist Steven Levy tracked Dr. Harvey to Wichita, Kansas, where the medic admitted that he still had his brain in a formaldehyde solution.

16. The size and mass of the brain have nothing to do with the intellectual abilities of a person. For example, Einstein's brain weighed one kilogram two hundred and thirty grams, which is less than the average weight of a human brain at this age - one kilogram four hundred grams.

17. Despite the fact that the male brain is 10 percent larger than the female, the female brain has more nerve cells and connectors, and it works faster and more efficiently than the male. Women process information more emotionally using the right hemisphere, while men use the left "logical" part of the brain.

18. Confidence can be generated without the need for a rational explanation, but simply by stimulating a certain part of the brain.

19. Long conversations on a mobile phone significantly increase the risk of a brain tumor. Mobile phones send 217 electromagnetic pulses to the human head every minute, that is, the brain is irradiated. The brain of a child is most susceptible to such radiation, in contrast to the brain of an adult.

20. A baby's brain can use up to 50% of all glucose in the body, which explains why babies need so much sleep. Lack of sleep in an adult significantly affects the functioning of the brain, leading to poor judgment and slow reaction. The brain makes our consciousness spend a third of our life in a dream, and at this time it is actively working.

21. Half of the brain can be surgically removed with no apparent effect on personality or memory.

22. According to scientists, the brain perceives rejection as physical pain.

23. In the human brain, there are areas with the following names: “aqueduct”, “beak and knee of the corpus callosum”, “cerebellar vermis”, “head of the caudate nucleus”, “bridle of the upper cerebral sail” and even “seahorse toes”.

24. An interesting fact is that most people who have had a body part amputated feel heat, pain or pressure in a non-existent limb. Scientists have not come to a single conclusion that would explain this phenomenon. Some say that the nerve endings that led to the amputated limb make new connections and send signals there, as if it were in place. Others suggest that the human brain has a memory of the entire body, and therefore it works with a limb even after its loss.

25. Another interesting fact is that the human brain does not feel pain, because there are no pain receptors in the brain. But this does not apply to headaches. When we have a "headache" - the pain is felt not by the brain itself, but by the tissues adjacent to it.

26. Half of our genes describe the complex structure of the brain, while the other half describes the organization of the remaining 95% of the body.

27. During orgasm, the brain produces so much dopamine that when it is scanned, the results will be the same as those of a drug addict under the influence of a hard drug.

31. The highest IQ - 210 was recorded by the Korean child prodigy Ung Yang, born in 1972. The child prodigy mastered algebra at the age of 8 months. By the age of 2, he was fluent in 4 languages. He entered the university at the age of 4 and graduated at the age of 15. In addition, Young is excellent at drawing and writing poetry. Now he lives in South Korea and enjoys what he was previously deprived of, that is, he takes a break from science, from work, from study.

32. The IQ of Anatoly Wasserman is 150. The highest national average is recorded in Japan and is 130. In Russia, the average result is 99 units. Belarus and Ukraine scored 92 points each. Naturally, these data are approximate and may differ in different sources.

33. The human brain continues to develop until the age of 50. Physical training helps keep the brain in good shape even after fifty. Regular sports activity contributes to an increase in the number of capillaries in the brain, which accordingly improves the access of oxygen and glucose. Former athletes with age are much less likely than others to experience brain diseases, sclerosis and schizophrenia.

34. Intellectual activity causes the production of additional brain tissue, which compensates for the diseased, so do not be lazy to “pump your brains” - this will save you from senile dementia and mental disorders.

Engaging in unfamiliar activities is the best way to develop the brain. Associating with those who are superior to you in intelligence is also a powerful means of developing the brain.

Ecology of life: The brain is the central organ of the human body. It is extremely complex and sophisticated. The functions of the brain were considered by the ancient Egyptians and Greeks in 400 BC. Hippocrates was the first to discover that the brain plays an important role in sensation and intelligence. Nowadays, everyone understands the importance of having a brain, but most of us know little about it. Here are some interesting facts for you.

The brain is the central organ of the human body. It is extremely complex and sophisticated. The functions of the brain were considered by the ancient Egyptians and Greeks in 400 BC. Hippocrates was the first to discover that the brain plays an important role in sensation and intelligence. Nowadays, everyone understands the importance of having a brain, but most of us know little about it. Here are some interesting facts for you.

1. And Latin cerebrum, and Greek ἐ γκέφαλος denoting the brain, firmly entered the Russian language. Cerebral palsy, encephalitis, encephalogram, even the Cerebro device in X-Men - everything contains these words.

2. There is no direct relationship between the weight (volume) of the brain and mental abilities. The heaviest brain known to science belonged to a person with idiocy (this is a diagnosis, not a curse!) and weighed 2850 grams, and Turgenev's brain weighed twice as much as the brain of Anatole France. For comparison: the heaviest brain of the living animals - in sperm whale (7800 g). At the same time, the weight of the brain of a hamster - one and a half grams.

3. The degree of development of the brain can be estimated by the ratio of its mass to the mass of the spinal cord. In cats, it is 1:1, in dogs - 3:1, in lemurs - 16:1, in humans - approximately 50:1.

1 - brain, 2 - central nervous system, 3 - spinal cord

4. There are no pain receptors in the brain tissue itself. therefore, surgical intervention in this area of ​​the body does not require anesthesia of the brain itself. However, this fact does not prevent the mass prevalence of headache.

5. Even Wikipedia states that the brain is made up of neurons that form synapses with each other. About about half of the cells that make up this organ - neuroglial cells, which until recently were left only a supporting role, - not a word is said. However, studies of the last ten years directly demonstrate the most significant role of glia in the functioning of the brain and even in thinking.

6. Humans have an olfactory brain. This is the name given to the collection of structures in the telencephalon (the most anterior and largest part of the organ) that is associated with the sense of smell.

Olfactory brain

7. Dinosaur brains were very, very small - even by human standards. More recently, archaeologists have found the skull of Sarmientosaurus (one of the titanosaurs, a pangolin 15 meters long and weighing 12 tons). Examination of the skull showed that the brain of this dinosaur was the size of an average tangerine.

8. The human brain in some cultures served as a gourmet dish and a source of terrible diseases.. Even in Neanderthal funeral rituals, traces of its eating from dead people can be traced. The Fore tribe of Africa also observed the custom of eating the brains of deceased sick people, which led to the spread of kuru fever, the discovery of prion diseases and the Stanley Prusiner Nobel Prize. As for the brain of animals, for example, a dish Cervelle de veau- is a traditional delicacy in French cuisine, veal brains.

Stanley Prusiner

9. Our brain is the body's biggest energy consumer.. Just 2 percent of our body mass (which it makes up) consumes as much as 20 percent of all energy coming from outside.

10. The main external distinguishing feature of the brain is the gyrus. As recently found out, they are formed purely mechanically. Field experiments of British scientists helped to understand this, they managed to set up an experiment with the formation of convolutions on a model printed on a 3D printer.published
