What is gray matter?
gray matter or gray mass is a type of nerve tissue found in the brain and spinal cord. It is named after its distinctive brownish gray color, unlike white matter, another type of nerve tissue that appears to be white because it is covered in myelin sorrows. Many people combine gray mass with intelligence and intellect because it is the main component in the brain, leading to slang terms as "using these gray cells". On the other hand, white matter is made of nerve fibers. The purpose of gray matter is to pass the sensory entry, collect information from the sensory organs and other gray matter cells and ensure that it gets where they have to go. The speed of communication is determined by white matter, so it is possible to think of gray and white mass as on the brain central processing unit.
People associate gray mass with intelligence for good reactions: When the brain is dissecting, it seems to be composed solely of gray matter. Before people understood the functioning of the body, they acknowledged that the brain is clearly different and manyThey assumed that all these gray cells had to do something. Gray matter also requires a lot of energy, using about 20% of energy at a given moment and taking advantage of abundant blood supply.
Interesting, some of the ancient cultures particularly did not bind the brain too important. For example, the Egyptians eliminated the brain during preparation for a funeral and believed that it was largely unnecessary. They believed that intellect and souls were concentrated in the heart, and some other cultures had a similar faith.
Brain research has shown that people have a different amount of gray matter. The denser the gray matter in the particular area of the brain, my probable brain owner will have intelligence or skill. People with an unusually high level of intelligence or unique skills tend to have a high level of gray matter in the brain parts that correlate with their ability. For example, qualified musicians have an unusually large Broca area.
By the way, for those who wonder why the brain is covered with groove and comb nets, the answer is that these folds increase the surface surface of the brain and maximize the number of neurons that can be packed in this area. An alternative would be to have a massive smooth brain that would require an absurdly large skull. In addition to looking nonsensical, a large skull for the host organism would be potentially dangerous and extremely impractical during birth.
