What is the current stage of human exploration of the brain?

In fact, the current brain science is indeed advancing by leaps and bounds, and the basic operating principles of the nerve are already very clear, mainly how various neurotransmitters and nerve signals are transmitted, and the brain plasticity structure built on this basis still needs to be analyzed slowly, but it does not prevent us from making a conclusion in advance: the brain is not mysterious For the functional structure of plasticity, the unsolved mystery of the human brain and the brains of other species, such as elephants, dolphins, birds, rats, and even insects, are not much more than that. But because it is the human brain, our own attributes, even if we understand ourselves more and more clearly, there will still be many people who are unwilling to admit this AI research and brain science are currently complementary to each other, so that we more and more realize: intelligence is not so magical, but a very common principle, not only intelligent organisms, organisms, semiconductors, and fluids can construct intelligent structures, as long as a signal transmission mechanism is formed, that is, neurotransmitters and nerve signals are not necessary, and they are replaced by other signal transmission methods, can also build intelligent processing mechanism, and can imitate exactly the same as the brain, and even the efficiency and function surpass the brain And the human brain consciously the most special last bottom-line function - creativity, has also been found by more and more researchers to conform to the fractal rules that exist in natural phenomena If the human brain is intelligent, then the whole universe is very intelligent, and the mystery of the human brain does not override everything and is absolutely unattainable Interestingly, Many people's understanding of their brains is the same as their attitude towards various things in themselves, ambiguous, and they want to know on the surface, but in fact they don't want to know at all, for fear that if they know, they will fall into the chaos of losing themselves.

While curious about his fate, he would rather mystify it, make some tarot cards and the like, not to explain but to make it more mysterious, how this subjective attitude of shame is presented in the brain, and why, it is worth studying.

As far as psychology is concerned, the study of the brain has also reached an unprecedented stage. To put it simply, it is to display the neural activity of the brain in the form of radio waves or images through some advanced equipment, and at the same time deliver various experimental tasks (mostly based on basic cognitive processes) to the experimental participants. Because the response to brain activity is dynamic and real-time, it is possible to observe which brain regions of the brain are more active in specific situations, under specific cognitive or emotional conditions, and in specific cognitive tasks.

Based on this, combined with the existing theoretical and empirical support, it is speculated which variable in the above specific experiment is controlled by which brain region, and which variable will affect the activity of which brain region. Looking further, after the accumulation of a considerable amount of research on the activity of various brain regions of the brain and its significance, it is thought that it is possible to ** the mental activity within an individual by observing the explicit brain activity. As for whether it can be achieved and how widely it can be used, it remains to be tested by time.

Human exploration of the brain has gone through thousands of years of human civilization, and today's exploration is not as advanced as 2,500 years ago. Our exploration today is based on the understanding of human ancestors, and uses scientific methods to prove the correctness of ancient humans' views on the brain and its conclusions. For the understanding of brain function, today's latest results:

1. It can be understood as the hard disk of the computer, which is mainly a storage function, which is huge to an unimaginable extent.

2. The computing function of the brain is many times higher than that of the world's most advanced computers.

3. The brain has the function of "antenna", which can receive information that humans can perceive and cannot perceive.

4. The brain is not the "CPU" of the human body, the brain is the executive mechanism of the "CPU" of the body, and the instructions of the body CPU are all directed by the brain.

5. Human beings have a third "eye", and the third eye of human beings is the "pineal gland" in the brain, which is a compound eye, three-dimensional, and can see in any direction without obstacles. At the same time, the vision of the pineal gland is not limited by time, three-dimensional space, or any obstacles, that is, the pineal gland can transcend time and space, ultra-macroscopic, and ultra-microscopic vision, so to speak, the vision of the pineal gland is omnipotent and omnipresent! At the same time, the pineal gland has the same sense of hearing, and its function is the same as that of vision, and it can also be said that it is also the third ear.

The popular saying that "only about one-tenth of the effective part of the human brain is used" may be a misunderstanding of the times when glial cell functions were not fully understoodThere is no credible theory that only nerve cells are at work in the brain, which means that the human brain develops about 10 percent.

The brain makes up the majority of the lumen of the skull. Approximately 2% of an adult's body weight, ie. 6 kg.

The weight of the brain is slightly greater in males than in females and is not related to body weight. The brain contains about 14 billion nerve cells, accounting for about one-tenth of brain cells, and the remaining ninety percent are called glial cells. Glial cells have a variety of functions such as providing nutrients to nerve cells, forming myelin sheaths, and improving conduction velocity.

The brainstem consists of the following four important structures:

1 MedullaThe medulla is located in the lowest part of the brain and is connected to the spinal cord; Its main functions are to control breathing, heartbeat, digestion, etc.

2 Pons: The pons is located between the midbrain and the medulla oblongata. The white matter nerve fibers of the pons, which lead to the cerebellar cortex, transmit nerve impulses from the cerebellar hemisphere to the other, so that they can coordinate the activity of the muscles on both sides of the body.

3 MidbrainThe midbrain is located above the pons and is exactly the midpoint of the whole brain. The midbrain is the reflex center of vision and hearing, and all activities such as pupils, eyeballs, and muscles are controlled by the midbrain.

4 Reticular systemThe reticular system, located in the brainstem, is a network of many intricate neurons. The main function of the reticular system is to control different levels of consciousness states such as arousal, attention, sleep, etc.

When a person's brain becomes smarter, it is dangerous.

Human beings are the shell, and the brain is consciousness.

Just like in Pacific Rim, whether the pilot wants to fight monsters or the mecha wants to fight monsters, I believe that if the mecha is conscious, it will definitely not be happy to fight monsters.

The human body is a mass of organic matter without the brain, like the soul, which is purely feudal superstition (in feudal superstition, the heart is the root of consciousness).

Let's put it this way, your brain controls your whole being. It's all about your brain giving orders to your body to do it. When your brain realizes that your life is in danger, your brain reacts and it simply won't be your turn.

We can only understand it from the level of anatomy, and we don't know anything about why it produces consciousness and how it works in detail.

There is no contribution, because the study of the brain has no practical significance for the results of society.

After people become smart, I don't see any normal person who can understand the words of this smart person, and the dots and lines can't be spoken, and they can't control the surface at all. When a person's brain becomes smarter, it is dangerous.

Of course, humans want to study the brain.

This question is a bit complicated, and I can't explain it clearly.

The study of the brain has no practical results for society.

The human brain is the most complex thing in the universe outside of the universe, and there is no one.

Why?

First of all, the human brain has about 100 billion neurons, and these 100 billion neurons are stored in about 1500 milliliters of the brain, and they are not stacked in your brain so regularly, which creates a huge obstacle to our research.

Because the space is too small, the human brain is extremely fragile and sensitive, and there are still a lot of capillaries in the brain, etc., which brings great difficulties to our study of the brain, compared to the study of the universe because it is too far away to know little, although the brain is very close to us, but to study it thoroughly, it is indeed not easier than the study of the universe.

If it takes us a mile to fully understand the human brain, we only know 3 inches at the moment.

Perhaps the biggest obstacle to this comes from the study of brain complexity, because it took billions of years of evolutionary time for the brain to construct these 100 billion neurons.

In fact, this is the fundamental reason why artificial intelligence has not yet made breakthroughs.

What would happen if the human brain was developed to 100%?

What would happen if the human brain was developed to 100%?

Very rarely, a few very smart people have developed 20 percent, usually 10 percent, and if it is fully developed, the human brain can completely crush the computer.

The current degree of human brain development is still very low, not more than 15 percent, but in human history, there are several human brains that have also created the highest degree of brain development, and the typical task is Einstein.

According to scientific research, only about 3% of the current human brain is developed. For individual people, it may be less than 4% developed, and the remaining more than 90% is in an undeveloped state.
