The brain includes telencephalon and diencephalon, and telencephalon includes left and right hemispheres. Telencephalon is the main part of the higher nervous system of vertebrate brain, which is composed of left and right hemispheres. It is the largest part of the human brain, and it is an advanced nerve center that controls movement, produces feelings and realizes advanced brain functions. In vertebrates, telencephalon is an enlarged part of the thin wall of the head of neural tube in embryonic period, and then develops into two hemispheres, mainly including cerebral cortex, medulla and basal nucleus. The cerebral cortex is gray matter covering the telencephalon surface, which is mainly composed of the cell bodies of neurons. The deep cortex consists of white matter formed by medulla or nerve fibers. The medulla, the basal nucleus, also has a gray matter, and the striatum is the main part. In medicine and anatomy, the word brain is often used to refer to telencephalon.

The human brain has always been an important field of unremitting research by scientists. According to the latest research, the main function of the brain is to analyze and generate samples, which can light up the thalamus. Before that, brain scientists realized that the human brain still has a lot of potential to tap. It is reported that not long ago, Dr. Bruce Miller of the University of California successfully discovered the "genius button" in the human brain. Miller studied 72 patients with brain injuries of various reasons in his own laboratory and found a rule-once a person has been injured under the right temporal lobe, he may become a genius in a certain field. For example, a 9-year-old boy became a talented mechanic after a partial brain injury; Another 56-year-old engineer became a great painter after some neurons in the right hemisphere were damaged by illness. Dr. Miller believes that this is because the talent that has been suppressed for a lifetime in the "genius area" of the brain is released after the death of damaged neurons. The corpus callosum, which connects the left and right hemispheres of the brain, has the function of information exchange, and the left and right hemispheres exchange information with it. Once a patient was tortured by epilepsy, scientists decided to remove the corpus callosum, which might solve the patient's pain and study the effect of the corpus callosum on the brain. Results After resection, the patient's pain was relieved, and the follow-up observation also found that the two hemispheres of the patient were "fighting in their own way", and they did not interfere with each other and did not know what the other was doing. In other words, when patients use the left hemisphere of the brain, they don't know what information their right brain gets.

The brain is divided into ancient brain and new brain. The ancient brain is the central part of the brain, which is equivalent to the medulla oblongata and spinal nerves of the brain. It is the center of life and the location of the brain that existed before human beings became human beings. The new brain is the marginal part of the human brain, which is equivalent to the cerebral cortex. It has been produced on the earth for at least 5 million years, but it has been changing according to some characteristics of the ancient brain, that is, it is a functional expansion of the ancient brain. This change is not random. It can be seen that birds are not very clever, but they are good at singing. This kind of singing has generally produced its function in the ancient brain, but in the new brain, it just changed this function. The new brain is the reason why human beings become highly intelligent. The ancient brain depends on the mother clock of the biological clock, while the new brain depends on stimulation, but they can interact with each other. The new brain can make functional changes in the old brain, such as faster heartbeat and breathing. An old brain can also hinder the development and function of a new brain. For example, a child is born with dementia.

Stimulation leads to the generation of memory blocks, which are stored on nerve cell membranes in the brain and exist in the form of chains, usually sugar chains or fat chains. Each block has at least one chain, for example, 1 is a chain, 2 is a chain,+is a chain, = is a chain, and 3 is a chain. These chains are generally located in one place (nearby), and 1+2=3 is another chain, that is, the latter chain is a kind of thinking chain because it is the result of thinking. It is the result of your brain combining 1 block, 2 blocks and+blocks under the control of the thinking rule "=". In the thinking center, 123+= all exist, which you learned in the student stage. When you were in primary school, learning 1+2=3 for the first time was a kind of thinking, and it will always be.
