25 facts about the human brain is incredibly powerful
The supercomputer inside the human skull simultaneously processes and face the facts, stores memories, regulates movement and speech, and makes decisions. Over the past few years, new technologies have allowed scientists to study the brain is even better.
So what do we know today? Website has collected 25 cases of wonderful, weird and incredibly powerful human brain.
1. The brain of a living person has a pink hue. The gray cells that make up 40% of our brains turn gray just after the death.
2. The brain is about 80-100 billion neurons (nerve cells). In the left hemisphere, nearly 200 million neurons ahead right.
3. The neurons vary in size from 4 to 100 microns in width. To get an idea of how it is not enough, take a look at the point at the end of this proposal, it is the order of about 500 microns in circumference, it means more than 100 neurons in the smallest can fit inside it.
4. Sex differences in the brain are controversial, but according to a study in 2014, published in the Journal of Neuroscience, gray matter in the brain more than women
5. A greater percentage of gray matter may be people humanitarian mindset.
6. Studies show that regular exercise can lead to an increase in gray matter in the hippocampus.
7. In men with less gray matter and more white cerebrospinal fluid.
8. White agent comprising the remaining 60% of the brain gets its color from myelin, which insulates axons and increases the rate at which electrical impulses are moved.
9. Fat can damage the heart, but it is good for the brain. More than half of the brain, including myelin consists of fat.
10. With a weight of about 1, 3 kg, the brain is only 2% to 3% of body weight, but consumes 20% of the oxygen in the body, and from 15% to 20% of its glucose.
11. The brain generates an incredible amount of energy. The energy of the sleeping brain would light a 25-watt light bulb.
12. The size of the brain does not affect mental abilities. For example, Albert Einstein's brain weighed 1, 2 kg, which is slightly smaller than the average size of the human brain.
13. The axons (neurites through which nerve impulses coming from the cell body to the innervated organs) in the brain of each person can be of the order of 161,000 km, and can envelop the Earth four times.
14. In the brain, there is no pain receptors. Therefore, neurosurgeons can cut the human brain in consciousness.
15. Do not believe the stupid myth of 10%. We use 100% of our brain.
16. The wrinkles of the brain, the so-called Smart, increase the surface area of the brain, allowing you to keep more neurons responsible for memory and thought.
17. Want more convolutions? Try meditation. The process of knowing their inner world is closely associated with the number of convolutions in the brain responsible for concentration, introspection and emotional control.
18. Tired of reading this text? Yawn! Yawn cools the brain, while the lack of sleep raises its temperature.
19. Even jaded brain can be productive. Some experts say that on the day the person skips 70,000 thoughts.
20. information in the brain goes through different types of neurons at different speeds ranging from 1, 5 kilometers per hour to 440 kilometers per hour (comparable with the speed of the fastest car in the world).
21. Our brain can scan and process complex images (such as the subway platform at rush hour) for only 13 milliseconds. It's pretty fast considering that flashing eye takes a few hundred milliseconds.
22. 15 years ago, scientists believed that the brain is formed during the first years of life. But recent studies have shown that adolescents occur critical changes in the brain, particularly in the prefrontal cortex and the limbic system, responsible for the adoption of social decision-making, impulse control and emotional processing.
23. When it comes to the brain, the delay in its development is absolutely normal. Of course, you legally become adults in 18 years, but, according to neuroscientists brain development continues until 25 years of age.
