If all the neurons in the human brain can be controlled independently for analysis and thinking, then the human brain is indeed very powerful, and its computing power can easily exceed that of an excellent computer, but after all, the brain is not only responsible for thinking.

The human brain is very magical. It has multiple centers, such as language center, movement center, emotion center, etc. The brain is also divided into cortex and gray matter. The cortex can be used for thinking, allowing people to analyze independently. One's own situation, and then take corresponding measures. The way a person treats things and other aspects can reflect part of the IQ; while gray matter can process external information and respond to the outside world with the assistance of sensory organs such as touch, sight, hearing, and chemical receptors inside and outside the body. To respond to various stimuli, this part does not need to be completely under voluntary control, and in fact it cannot be done. For example, breathing and heartbeat in the brainstem. People can hold their breath but cannot hold their breath forever. The brain will force breathing; heartbeat It is not under your own subjective control, but it will be affected by your emotions.

The brain as a whole can contain as many as 100 billion neurons, and the number of synaptic connections between neurons can be 100 trillion. From this order of magnitude, the brain may have great potential, but The number of neurons in the cerebral cortex is only about 20 billion, and the cortex not only contains neurons for movement and thinking, but also components for regulating body temperature.

The human brain is very complex, and every point in the brain network has its role. Usually people use a certain area just as an instinctive behavior, which is stimulated by the outside world, but some geniuses Certain areas can be actively deactivated. But as for how to activate it, science doesn’t understand. The development of brain potential is actually to make the connections between various blocks in the brain network closer, and we can even actively activate a certain area by ourselves, which is usually passively activated.
