To date, there are a number of interesting numbers that reflect the structure and functioning of the brain. So, according to rough estimates, it contains about 100 billion neurons – cells that process, organize and remember information. If you add up all the nerve fibers that are inside both hemispheres, they will stretch into a line half a million kilometers long. The surface of the brain is not smooth, it has a network of convolutions, which eventually form an area of about 20 m2.
No less impressive is the work of the brain. Impulses from one cell to another and to organs are transmitted at a speed of 288 km / h, but with age, the speed slows down a little – by about 10-15%. Therefore, older people are slower, think longer, remember worse. If we compare the brain with a computer, then its memory capacity reaches 5 Petabytes. To understand such a volume is 300 years of continuous film viewing. But that’s not all of the incredible abilities of the brain, it’s such an amazing and unique organ that neuroscientists are constantly learning something new.
