1. The nerve impulses from the brain and to the brain are transmitted at a speed of about 170 miles per hour. Have you ever wondered how you can react so quickly to things around you or why your stinging finger hurts right away? It is due to the super-fast movement of nerve impulses from the brain to the rest of the body and vice versa, bringing the reactions to the speed of a large motor sports car.
2. The brain works on the same amount of energy as a 10 watt bulb. The cartoon image of a light bulb above your head when a big thought occurs is not too far from the truth. Your brain generates as much energy as a small bulb even when you sleep.
3. The human brain cell can hold 5 times as much information as the British Encyclopedia. Or any other encyclopedia that matters. Scientists have not yet been able to decide on a definitive amount, but the brain’s storage capacity electronically is considered to be between 3 or even 1,000 terabytes. The National Archives of the UK, which contains over 900 years of history, only takes up 70 terabytes, which means that your brain has damn impressive memory power.
4. Your brain uses 20% of the oxygen that enters the brain through the lymphatic system. Only the face, which represents about 2% of our body mass, consumes more oxygen than any other organ in the body, which makes it extremely susceptible to damage from oxygen deprivation. So, take a deep breath to keep your brain happy and swim in the oxygenated cells.
5. The brain is more active at night than during the day. Logically, I should believe that all the complicated movement, calculations and tasks and the general daily interaction requires our brain more than when lying in bed. It seems that the opposite is true. When you turn off your brain it lights up. Scientists do not yet know why this is happening, but they can thank the brain for the hard work they do while they sleep for all those pleasant dreams.
6. Scientists say that the more you have an I.Q. the bigger you dream the more. While this may be true, don’t take it as a sign that you are smart enough if you can’t remember your morning dreams. Most of us don’t remember many of the dreams and the average duration for most dreams is only 2-3 seconds – just not long enough to record.
7. Neurons continued to grow throughout human life. For years scientists and doctors have believed that the brain and neuronal tissue could not grow or regenerate. Because it does not act in the same way as many other parts and tissues of the body, neurons can grow and regenerate throughout your life. , adding a new dimension to the study of the brain and the diseases that affect it.
8. Information flows at different speeds within different types of neurons. Not all neurons are the same. There are several different types in the body and transmission along these different types can be as slow as 0.5 m / sec or as fast as 120 meters / sec.
9. The brain itself cannot feel the pain. While the brain may be the center of pain, when you cut yourself or burn yourself, the brain itself has no pain receptors and cannot feel the pain. This does not mean that the head cannot cause pain. The brain is surrounded by a lot of tissues, nerves and blood vessels, which have a lot of pain receptors and can give you a dreadful headache.
10. 80% of the brain is water. Your brain is not a firm, gray table as you saw on TV. Brain tissue is represented by a jelly-like pink mass, as are other organs, due to blood loads and the high water content of the tissue. So, the next time you feel dehydrated drink onions to keep your brain hydrated.
11. For the average adult in a resting state, the brain consumes about 20 percent of the body’s energy. The brain’s primary function — processing and transmitting information through electrical signals — is very, very expensive in terms of energy use.
