#8 – Why the brain covered with convolutions?
The human brain has a distinctive sinuous texture. Formation and gyri depend on several parameters. The growth of the gray matter of the brain and the thickness of the material determine the formation of the brain.
Scientists have discovered that gray and white matter are similar in hardness, but they grow at different rates. One can assume the structure of convolutions depending on the size of the brain. The larger the brain, the greater will be proportional difference between the growth rates. As the gray matter of the brain grows, white substance begins to bend and form convolutions, which increase the surface area.
