Seeing that Han Feng agreed to join the Department of Neuroscience, Professor Li Zhongwen was very happy, and the relationship between the two became closer.

Li Zhongwen was able to talk to Han Feng so speculatively, on the one hand, because he couldn't find someone he could communicate with in China

As they talked, the topic shifted to the question that Han Feng had raised last time.

Li Zhongwen already knew at this time that Han Feng was able to ask that question, it was not an accidental factor, he even regarded Han Feng as a peer in this field who was about the same level as himself, no, in some aspects, he was even better than himself.

Li Zhongwen said: "Han Feng, the question you mentioned last time was very good, but unfortunately I was in class at the time and couldn't discuss it in detail...... As I said, actually, this happens to be a topic that I've been working on lately, so I'd love to hear what you think about neural impulses. ”

The current scientifically accepted view of nerve impulses is based on the conclusion reached by several scientists in the sixties of the last century: nerve impulses are electrical impulses.

However, they also came to an important conclusion: the meridian pulse does not generate heat during conduction. This conclusion contradicts the physical laws of thermodynamics.

This is a world problem that has plagued scientists all over the world for decades, and now, Li Zhongwen actually asked Han Feng this question in turn, which shows that he really attaches more importance to Han Feng, and he is no longer a student who has just begun to study such a subject.

Han Feng pondered for a while, organized the language in his mind, and said: "Actually, I only asked this question in a hurry in class at that time, I really didn't expect this to be a worldwide problem, let alone that this is one of your research topics, it's really a bit of a coincidence." To be sure, nerve impulses do not generate heat during conduction. Han Feng himself has specially observed this conduction process from a microscopic perspective, so he can naturally be so sure.

"And the electrical properties of nerve impulses have also been confirmed, and the laws of thermodynamics have been proven to be correct today, so my view on this is that nerve impulses may have other properties besides electrical properties, and this property is probably difficult for us to imagine, and you surely know that such examples are not non-existent. ”

Li Zhongwen nodded: "I understand what you mean." Light, like light, has both the properties of waves and particles, and before the discovery of particles, people could not have imagined that light still had this quality. ”

"Yes, that's exactly what I meant. "It's easy to talk to smart people, and you can understand it without too much explanation," Han Feng continued, "Quantum mechanics has proved that all matter has wave-particle duality, and I wonder if the motion of electrons is also a wave, and the nerve impulse may also be a mechanical impulse?"

Wave-particle duality is a theoretical framework established by quantum mechanics in the early twentieth century, which states that all matter can exhibit two properties, wave and particle, under certain circumstances.

The reason why Han Feng said this was not casual, he did have his own considerations, but he was just his conjecture, he didn't bother to prove whether this point of view was correct, this is not something he cares about now, but since Li Zhongwen asked, he said it, maybe he can give him a little enlightenment.

"Mechanical Pulse ......" Li Zhongwen showed a contemplative look, and the statement proposed by Han Feng was very different from the direction he had been researching. If he heard him say this before he didn't know Han Feng's true level, Li Zhongwen would definitely only laugh it off as a whimsical idea, and he wouldn't pay much attention to it, but now it's different, and he will at least think about Han Feng's words seriously.

Han Feng didn't say much more, and instead asked a question he had just encountered while reading the book.

"Mr. Li, Freud's personality theory says that consciousness is a fragment of memory, and if an idea and thought cannot be expressed in the form of a symbol, it cannot be presented as consciousness. Can the symbols here be understood as human language and writing?"

Li Zhongwen nodded: "It can be understood in this way. The emergence of language and writing is the greatest milestone invention in human history, and it is precisely because of the emergence of language that human thinking is effectively transformed into memory. ”

In this way, language plays a crucial role in human memory. ”

"Yes, the role of language is very obvious, and without language, a lot of our consciousness would not be able to form effective memories. For example, our sense of smell is like this, you suddenly remember a certain smell, but you can't say it, you can't simulate what the smell is like in your brain, and only after you smell a certain smell again can you say, yes, this is the smell. Of course, our predecessors have invented some words for us, such as spicy, rose fragrance, etc., without these words, the brain will not be able to remember the characteristics of this smell, this is the effect of language on memory. This is true of taste, vision, and the consciousness that the internal organs want to express, and these memories are symbolic, abstract, vague, and generalized. Li Zhongwen was triggered by Han Feng to talk about sex, and expounded his understanding of this aspect in one breath.

In fact, these theories were developed in the course of his research on artificial intelligence.

Vague memories?

Li Zhongwen's words made Han Feng also surprised.

Seeing that Han Feng seemed to be very interested in his statement, Li Zhongwen continued: " In fact, human language is a high summary of everything in nature, not like a computer to completely copy, the same is true of memory, although the capacity of the human brain is huge, but it is not possible to save all the information that people see, hear, and feel in their lives to the brain, of course, it is not to intercept a piece of it, like a DV to shoot into the brain, but through the brain's natural filtering mechanism, selectively process, extract, and finally organize into memory for preservation。 I think this is the biggest difference between computers and humans, like now, those robots that simulate humans have indeed done a good job in logical computing, but they have completely preserved the information of the outside world, and there is no generalization at all. ”

Although he is not engaged in computer science, Professor Li Zhongwen has a deep knowledge of neural networks, and is naturally very interested in the topic of simulated artificial intelligence, after all, this topic is not only carried out by computer scientists, but also by biologists.

Li Zhongwen's words turned a huge wave in Han Feng's heart, and he suddenly found that he had once again gotten into a dead end and had been thinking about problems with inertial thinking.

The human brain is indeed automatically filtered for external information, and this information is often the center of gravity of all information.

Han Feng remembered a document about the human eye that he had seen before, which mentioned that the reflection of the human eye on the external world is not a complete mirror image of the external world, but the result of processing, and the brain will automatically select the most critical information to present, which is often highly generalized, and those secondary image information are blurred. A good example of this is when we stretch out our fingers and slowly move them in front of our eyes, so that we can only approximate the shape of the fingers and determine the direction in which they are moving, but we have no impression of the specific details of the fingers (in their natural state). If you close your eyes at this time, your brain will automatically complete the movement of your fingers.

Memories turned out to be vague and highly generalized!

Han Feng thought of a new idea that he could double the storage information of his brain disk, according to this idea, although the capacity of the brain disk has not increased, the stored information can be greatly increased, from another point of view, it is equivalent to expanding the capacity of the brain disk.

Han Feng really appreciated a sentence - listening to your words is better than reading a book for ten years!

Recommend the alternate history "The Noble Son", ISBN: 188411

Purity is the pass of the ****, and **** is the epitaph of the pure. History is actually a ****, whoever has a hard crotch in his pants is her benefactor, and he puts on his pants after finishing his work, and he has the reputation of a thief.

So let Chen Qing, who traveled from modern times to ancient times and became a noble son, be **** for this heroic history!
