Chapter 6： develop the human brain

The three civilizations are located in three different directions of the solar system. The distances are long and short. The longest distance is more than 20,000 light-years, and the shortest is seven or eight thousand light-years. They must send troops together to assist the Red Devil civilization located three thousand light-years away from the solar system. .

It means that they master 'wormhole' technology that spans super long distances.

If they were allowed to discover human civilization, with the current technological level of human civilization, they would definitely not be able to resist this kind of power.

The only thing that is more reassuring is that from the very beginning, Li Yi cautiously did not disclose the location of human civilization on the earth in the star map space. At the same time, human civilization is now in the early stage of moving towards planetary civilization, and the transformation of the solar system is still in the process. In the primary stage, there is not much movement. For alien civilization, human civilization is in a silent state, and the exposure probability is greatly reduced.

The only question now is that I provided Bellis with the videos of the two warring civilizations. Which three banking civilizations will definitely be curious about its origin, and whether they have increased their search for other civilizations? It is unknown. However, this kind of The situation is very likely to happen.

"Li, if it's all right, I'll go to work first. I'll definitely try my best to get the information for you." Bellis said goodbye to Li Yi.

"No! Just take it easy! Just keep on keeping your friendship with them, let's take your time with the intelligence thing!" Li Yi stopped Bellis and urged.

"Okay!" Bellis gave Li Yi a strange look and nodded.

Soon, Bellis disappeared in the star map space, and Li Yi fell into deep thought. He was thinking about how to make the technological level of human civilization develop faster.

Although he has obtained a large amount of stellar technology from the star map space, the development speed of human technology is still at a flat level. The fundamental reason is that the number of human scientists, especially the top scientists, cannot meet the requirements of the era of human interstellar civilization. .

For example, the development of modern science and technology in human civilization is entirely the contribution of top science.

In human history, Einstein, the top scientist, has made an indelible contribution to human civilization by himself. 1905 is regarded as Einstein's "miracle year". The extremely original and subversive papers have completely changed the face of modern physics and set off two great revolutions in science and physics.

At the beginning of the 20th century, the entire physics community was faced with a major crisis. Many observed phenomena and experiments could not be explained by the theories of classical physics. Through his research, Einstein successfully solved various inexplicable problems that were in chaos at that time, and also brought about the quantum revolution and the development of quantum physics.

Now, mankind still needs to train more advanced scientists. There are several methods to greatly increase the base of the high-quality human population.

If the entire solar system is built into a Dyson sphere, it is expected to support 10 trillion human beings. If the human population is 10 billion, a top Einstein-level scientist can be born, and 10 trillion human beings can give birth to 1,000 top scientists, which is enough to make the development of human civilization. pair of wings.

Or, use biotechnology to greatly improve the overall intelligence of human beings and increase the probability of the birth of top scientists.

Thinking of this, Li Yi was moved, and in the public area of ​​the library, he searched for technical knowledge to improve human intelligence.

A week later, Li Yi appeared in the biological laboratory of Xingyao Experimental Center, accompanied by Sun Bingwen, Professor Wei Zhihan and other experts and professors in the field of biology.

The virtual screen of the biological experiment command room shows biological experiments on the lunar base.

More than a dozen medical monkeys injected with adaptive gene-enhancing agents are undergoing various testing studies.

"All the injections of the adaptive gene enhancement drugs have been completed. A total of 12 medical monkeys have undergone the fifty-seventh experiment. The overall side effects have been eliminated. Mr. Li, the animal experiments of the adaptive gene enhancement project have been passed, and human experiments can be started. "Professor Wei Zhihan looked at Li Yi excitedly and concluded.

"It's hard work, you've put in too much effort for this project." Li Yi nodded and thanked him.

"It's what we should do! If it weren't for your unconditional support, we wouldn't be able to do this project." Professor Wei Zhihan looked at Li Yi with a modest smile and said with emotion.

"How about the strengthening effect? ​​What effect can the experimental monkey achieve after strengthening?" Li Yi turned to look at the big screen and asked with concern.

"The overall effect is very good. All the experimental monkeys were injected with the enhanced gene experimental agent, all of which are the existing side effects genes. There is no negative attribute heritability in the third generation of culture. The strengthening effect is very obvious. , the cosmic radiation resistance is increased by about 10 times, the low temperature resistance is increased to -70 degrees, the surface skin is thickened, the bone density is adapted to the vacuum environment, and there will be no more loose diseases..." Professor Wei Zhihan eloquently explained the adaptability of use. After strengthening the genes, the experimental monkey's current strengthening data, the more he talked, the more excited, his eyes were shining, just like a mad scientist.

"Yeah! The experimental effect, the adaptability of the medical monkey to the cosmic environment, far exceeded the expected effect."

"We succeeded, this time it's definitely no problem!"

"Yeah! The third generation of fertilized eggs was successfully cultivated, and 99% of the inheritance of negative genes was ruled out! We finally made it!"

...

As soon as Professor Wei Hanzhi finished speaking, all the researchers at the scene cheered excitedly with your words and my words.

It has been almost 10 years since the establishment of the adaptive gene enhancement project. However, the progress of this research project has been very slow. Professor Wei Zhihan and other scientific research teams have been tortured crazy by this project.

In order to make this project possible, the Xingyao Experimental Center has invested several trillions of huge research funds.

Now, the sunshine of green hope finally appeared, Professor Wei Hangzhi and all the scientific research members of the scientific research team were all excited.

"At present, animal experiments have been made, and it is uncertain whether the human experiments will be successful!" Sun Bingwen poured cold water in disapproval.

The gap between animal experiments and human experiments is still quite large.

In the field of medical research, animal models are used to study the etiology, pathogenesis and treatment of diseases, and some have made breakthroughs. Preclinical animal experiments also provide advanced data for revealing the nature of the disease and future clinical treatments.

However, the research and development of a new drug, especially a genetic drug, must undergo sufficient preclinical research and demonstrate safety and efficacy in animal experiments before clinical trials can be conducted after review and approval.

Drug clinical trials are carried out on volunteers (patients or healthy people) to confirm or reveal the effects and adverse reactions of the test drugs, as well as the processes of absorption, distribution, metabolism, and excretion, and to evaluate their safety and effectiveness. One of the most important links.

Preclinical animal experiments are carried out under certain conditions, and the results and conclusions obtained can only be limited to such conditions, and cannot be blindly expanded. This is the basic principle of scientific research, and these specific conditions are difficult in clinical trials. accomplish.

Secondly, preclinical animal experiments only need to observe the effect of a certain factor, and do not need to consider the impact on the overall life of the animal. Some intervention experiments may have positive effects on model animals in some aspects, but often cause other serious damage. It is precisely because of the simplicity of animal experiments that it is relatively easy to obtain breakthroughs.

However, the clinical application of animal experiment results needs to be very cautious, which is necessary for rigorous scientific research.

The importance of clinical trials is far greater than preclinical experimental research, because the most basic properties, efficacy and safety of drugs are ultimately tested by it. According to statistics, it generally takes more than 10 years for a class of new drugs to start from basic research until they are recognized, produced and marketed. The average development cost of each new drug is more than one billion yuan, of which more than 70% of the cost and time are Spending on clinical research shows the importance of human trials.

That's why there is a fundamental difference between animal experiments and human experiments.

"Director Sun is right, but the adaptive enhancement gene project has been researching for so long, and such an obvious breakthrough should be celebrated." Li Yi smiled and gestured to the scientific research workers.

"Thank you Mr. Li for your encouragement. We will continue to work hard and strive to pass the human experiment as soon as possible." Professor Wei Hanzhi said excitedly.

Li Yi nodded, looking at Professor Wei Zhihan and suddenly asked: "The adaptive gene enhancement project does not improve the IQ of the human brain, right?"

"Yes, the adaptive genes you provided have no genetic information about the human brain." Professor Wei Hanzhi nodded and confirmed.

"Mr. Li, do you have any plans for this?" Sun Bingwen felt something, looked at Li Yi and asked.

"Yes, if we can develop genetic medicines that enhance intelligence, it will be very important to the subsequent development of human civilization. Artificial intelligence is powerful, but ultimately, the development of civilization still depends on us!" Li Yi nodded and said solemnly.

"Are there any of you who are more specialized in the human brain? I hope someone will come out and undertake this brain development project!" Li Yi said bluntly in public after looking at the faces of the scientific research experts.

Hearing this, all the scientific research experts are eager to try, and their hearts are unceasing.

"Professor Qian and Professor Ning are both experts in this field. Who among you is willing to take on this responsibility!" Professor Wei Zhihan gestured, looking at the two older professors.

Hearing this, Li Yi looked at the two people who raised points with Professor Wei Hanzhi. He also knew them. They were Professor Qian Hongliang and Professor Ning Qiming.

"Let Professor Qian take over! The adaptive gene enhancement project, I can't go away!" Professor Ning Qiming said bluntly.

"I also have a mission here. Professor Ning is good at human brain research!" Professor Qian Hongliang frowned and followed suit.

"Two professors, you don't need to be humble and give way. Why don't you talk about your understanding of the human brain field and the technical direction of developing the brain field? How about I decide?" Li Yi smiled and suggested.

Professor Qian and Professor Ning looked at each other and nodded.

"Okay! I'll come first!" Professor Qian nodded rudely, looked at the command screen, and then called up a stereoscopic view of the human brain.

"The screen shows a human structure diagram. The human brain consists of the cerebrum, cerebellum, diencephalon and brain stem. Among them: the cerebrum is the highest part of the central nervous system and is divided into left and right cerebral hemispheres, both of which are composed of nerve fibers. The corpus callosum is connected, and there are many curved fissures on the surface of the cerebral hemisphere, called sulci, and the protruding part in between is called gyri. These sulci and gyri are like a piece of folded silk, once flattened, It's the size of half a regular newspaper."

"Every organ of the human body has a 'cost', which can be divided into "expensive" and "cheap". The process of organ formation requires a lot of energy and resources, so nature's 'man-making' uses the least amount as possible. Energy and resources are the lowest cost to maximize functional efficiency. There is no doubt that the cost of generating brain organs is very high, and it can be said to be very "expensive", which is more precise than any instrument in the world."

"There are about 14 billion nerve cells in the human brain, accounting for about one-tenth of brain cells, and the remaining 90% are called glial cells. These glial cells provide nutrition for nerve cells, form myelin sheaths to increase conduction velocity, etc. There are many functions, and it is often said that "the part of the human brain that is effectively used only accounts for about one-tenth", that is, it may be due to a misunderstanding that the function of glial cells is not fully understood, and it is believed that there are only nerve cells in the brain. At work, that is to say, there is no credible theory that the human brain develops 100 percent."

"With the deciphering of human genes and increasing the activity of human brain cells, it is very feasible to develop deep-level applications of the human brain!"

"The brain is divided into left brain and right brain. The left brain is responsible for the analysis and concentration of thinking, and the right brain is responsible for the imagination, perception and diffusion of thinking ~ www.novelhall.com~ The development of the human brain refers to objective stimulation and subjective adjustment, to guide and exploit the remaining possibilities in the cerebral cortex, the possibilities of the human cerebral cortex, including the creation of content for brain functions that were not there before."

"After understanding the types of neurons, figure out the output fibers and input fibers of each type of neuron in each brain area, and where the information is going to be sent, through the structural map, find out the electrical activity of neurons, and see when the radio waves are What will appear, and how the information is transmitted, this is the activity map. After all the maps are obtained, the final function of the neural circuit can be analyzed.”

...

According to the brain structure diagram on the screen, Professor Qian Hongliang eloquently introduced his knowledge of the direction of developing the brain, and described the direction of developing the brain to everyone. According to his idea, genetic medicine is used to change and strengthen the brain.

Professor Qian introduced Wan, and then it was Professor Ning's turn. Professor Qian had already introduced the structure of the brain very clearly. He skipped this process and directly explained the technical direction of developing the brain.

Compared with Professor Qian's use of genetic medicine to develop the brain, Professor Ning's scientific research direction is very different. He proposes to use mature brain-computer intelligence technology, combine human brain with artificial intelligence, and strengthen human brain through intellectual brain.

Faced with these two technical solutions, Li Yi pondered and weighed up.
