Transcript of Human Brain

prezi made by Meiramov Daniyar 10"B" class
The brain does not feel pain
In the brain, no pain receptors. Therefore, surgeons can perform operations on the brain without entering patients anesthesia. This helps prevent damage to any visual or motor functions. But it looks pretty scary.
Interesting facts of Human Brain
Children who are learning two languages ​​at the age of five, alter the structure of their brains, and in adulthood have a much denser gray matter.
The average number of thoughts that are carried in our minds every day 70,000.
Living brain is so soft that it can be cut using a table knife.
The adult human brain weighs on average about 3 lbs. (1.5 kg) with a volume of around 1130 cubic centimetres (cm3) in women and 1260 cm3 in men, although there is substantial individual variation. Men with the same body height and body surface area as women have on average 100 grams heavier brains, although these differences do not correlate in any simple way with IQ or other measures of cognitive performance.
Thanks for attention!
The brain is the center of the nervous system in all vertebrate and most invertebrate animals—only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have one, even if diffuse neural tissue is present. It is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell.
In our brains 100,000 miles of blood vessels
The brain also consists of one hundred billion neurons , as much as in the whole galaxy. Using only 17% of the body's energy and 20 % oxygen , his weight is only 2 % of the body , with spillage brain creates an electric field in the 10-23 watts , which is sufficient to ignite the bulb. Composed of 75% water , the brain involves more than 100 trillion synapses interconnecting neurons , and also enough space to accommodate the five volumes of the Encyclopedia Britannica , or 1,000 terabytes of data . The myth of the incomplete use of the brain is not true. You always use your brain completely.
Einstein's brain kept still
When in 1955 Albert Einstein died, his skull was opened to extract from it the brain. Dr. Thomas Harvey carried out this operation in seven and a half hours after his death. Presumably, this was done for research purposes.
There is a difference between the right and left hemispheres
The brain is divided into two hemispheres. They work concurrently, but the left hemisphere is responsible for rational, analytical thinking, and the right - for visual and thinking. They also work as opposed to - you lift your left leg and right side of the sensations perceived. But there is a very strange thing, if half of the brain is turned off, the man still survives.
Highest IQ - 210 in Ung Yang
Born March 8, 1972, Ung Yang mastered algebra at the age of 8 months. By age 2, he was fluent in four languages. He entered the University of 4 and finished it in 15. But he is strong not only in the exact sciences. He also paints and writes excellent poetry. He now lives in South Korea and enjoys the fact that he did not have before, such as childhood.
