What s going on with the wrinkles of the brain, and what is the cause of the wrinkles in the brain?

The surface part of the brain is called the cerebral cortex, and the average thickness of the human cerebral cortex is millimeters, and the surface of the cortex is highly expanded and curled, forming many furrows and fissures.

We can see that there are obvious differences in the size, smoothness and folds of different animal brains, and the vertical and horizontal furrows on the human brain, just like the surface of walnuts, in medicine these folds have their own professional names, the folds on the surface are called gyrus, and those deep grooves are called sulci.

In fact, looking at animals in nature, it seems that only the surface of the human brain is covered with such folds, and the brains of most animals are actually smooth, especially rats and rabbits, their brain surfaces are very smooth, and the brain capacity is also very small. The size of the brain also determines the intelligence of the organism, the larger the brain capacity, the more information and things can be processed, and the more intelligent the animal.

The human brain begins to form folds in the embryo, and it begins to gradually form around the 20th week of the fetus, and the folds of the brain are closely related to our IQ, the brain with more folds has a larger surface area, so that it can accommodate more neurons, and it is also able to process more information, and the depth of the folds increases the speed of signal transmission between brain cells, so the more folds, the less time and energy the cortical folds can consume to transmit information.

In fact, everyone's brain looks different, but the main groove of the brain is still the same between each individual, if a part of the brain cannot develop normally, then it will lead to brain dysfunction, and the fetus produced will have intellectual deficiency.

The degree of folds in the brain is actually inseparable from our acquired learning, and even the acquired learning factor is more important, after studying experts in various fields, their brain functional areas are larger than ordinary people. As we learn, the structure of the brain gradually improves, and the folds in the brain increase. Learning to live to be old, learning to be old is really not wrong, learning can make us smarter.

Because the cerebral cortex grows faster, and the related substances of the brain inhibit its growth, and the genes have an effect on the brain, folds appear.

Generally, it is because of some tumor in the brain that the brain is squeezed, so the brain will be folded.

It is because people are becoming smarter, people are learning, the stronger the learning ability, the more wrinkles there will be, and people are creatures who learn and live to be old.

This is a natural physiological structure, which belongs to the physical properties of a human physiological structure. So the human brain has folds.
