It has been five days since I talked to Wang Xuezheng about patents last time, and during these five days, Qin Ran spent most of his time in the Neural Exchange Technology Laboratory.

The experiment of neural exchange technology has always been the focus of Qin Ran's attention, and there are two reasons for this.

First, neural exchange technology is a new technology, and I don't want other technologies to have experience accumulation.

Second, neural exchange technology is already related to the second round of driver testing, and only drivers who have passed the second round of testing can organize training.

Driver training is not so simple, being able to pass two rounds of testing is only a prerequisite, mecha basic operation knowledge, combat training, cooperative combat, etc. all need to be trained, which takes a lot of time.

If you want to build a mecha and train a pilot at the same time, you have to complete the neural exchange technology in advance, leaving some time for later training.

Wan Li is the main person in charge of the neural exchange experiment, and it was also set by Qin Ran at the beginning.

Wan Li herself is 48 years old this year, is a doctor of neuroscience, neuroscience can actually be divided into a kind of biology, the real authoritative neuroscience experts are basically on the side of biological genetics, Wan Li is already the only neurological expert Wang Xuezheng can find, to be honest, her technical ability is not very strong, when the original debriefing report, almost did not pass.

But let her participate in the giant mecha project, this is also the result of Wang Xuezheng's second thought, you can't go to biological genetics to dig one over, who knows if the person who dug it is really helpful, or determined to help.

Based on this consideration, Wang Xuezheng recommended Wan Li, his idea is very simple, the lack of technical level can be made up for by Qin Ran, but the position must be on the side of the giant mecha project.

The neural exchange experiment has been going on for more than ten days, and there has been no major breakthrough so far, so Qin Ran can only play in person.

In the laboratory, Qin Ran was explaining part of the knowledge of neurology.

"Do you know why I designed a spinal cord clip on the driver's combat suit? ...... The reason is very simple, as we all know, the central nervous system of human beings is divided into cranial nerves and spinal nerves, and all neural activities must be involved in the central nervous system, however, unconditioned reflexes only need the participation of spinal nerves and brainstem, and when the driver is driving a mecha to fight, unconditioned reflexes are also an important part of tactical actions....."

"Can anyone tell me what the relay gel does?"

Dr. Wan Li immediately responded: "The relay gel is the medium used for the neural connection between the two drivers. ”

Qin Ran nodded, very satisfied with this answer, it seems that the other party has put in a lot of effort, and has a certain understanding of the new terms mentioned in the information he gave, but this knowledge is still not enough, so Qin Ran asked again: "Then how does the relay gel realize the neural connection of the two drivers?" ”

Qin Ran asked, and there was no sound at the scene, their previous experiment was stuck in this ring.

Seeing that everyone was silent, Qin Ran was not surprised, after all, it was a new technology, and it was normal to not understand it.

"Then you know about glial cells!"

This question is not difficult, and someone immediately answered: "Glial cells, also known as glia or glial cells, are widely distributed in the central nervous system, and all cells except neurons are about ten times more numerous in the central nervous system than neurons." It has the function of supporting and nourishing neurons, and also has the function of absorbing and regulating certain active substances. ”

While the other party replied, Qin Ran nodded, and finally gave the other party an affirmation: "The basic knowledge is good." ”

After receiving Qin Ran's praise, the researcher's face turned red with excitement.

But Qin Ran didn't care about this, he continued: "Glia has the function of connecting various nerve components, and the working principle of relay glia is to integrate glial cells to connect two different human nerve components. ”

After listening to Qin Ran's explanation, everyone showed expressions of sudden realization.

However, there are also people who question it, such as Wan Li.

"Qin Gong, is this connection stable? After all, the human body has an instinctive rejection of external objects, and the same is true for neurons, and if the connection is unstable, then it will cause serious consequences. ”

"Indeed, this connection is unstable!" Qin Ran first affirmed Wan Li's conjecture, "Just like blood type, when transfusing blood, doctors can only transfuse the same type of blood to patients so that they will not be rejected by human body functions." ”

"But! The blood type can be found in the same type, so can neurons, maybe you understand this concept very vaguely, then I will briefly say, if you want the connection to remain stable, then you must let the neural electrical signals and chemical signals find resonance. ”

"As for how to explain this resonance, let's first review the way human memory is stored."

"The human memory storage part is the hippocampus, and the human cerebral cortex, cerebellum, almonds and other structures encode memory information into neural electrical signals and chemical signals, which are encoded into network structures to form short-term or long-term memories. And when I say resonance, it's actually more like a kind of memory deception, that is, when another person's nerve accesses, the brain mistakenly thinks that it is the same signal input, without repulsion, so as to stabilize the neural connection. ”

"Of course, how much resonance can be generated between two people, how much signal of memory deception, which determines the stability of the neural connection, the higher the degree of stability, the better the tacit understanding between the drivers, and the higher the combat effectiveness."

When Qin Ran finished explaining in one breath, the audience applauded, which was incompatible with the quiet laboratory.

But after the applause, Wan Li still had questions:

"How can you be sure that the neural connection between two people will be successful?"

"There is no way to solve this, you can only try and make mistakes one by one, of course, what can make two people resonate, there must be an intimate relationship between them, because only if you have lived in the same environment, the memory will be consistent."

"What about the consequences of trial and error? Does it cause insanity or other neurological disorders? ”

"Dr. Wan, you may be overthinking!" Qin Ran replied confidently: "You seem to have forgotten the existence of microglia, microglia are affected by the stimulation foci and will become macrophage-like phagocytic microglia, and the role of this cell is to engulf necrotic nerve components. ”

Qin Ran exhaled and said with an affirmative expression: "So, if trial and error fails, then the worst result is that the person who tries and makes mistakes will lose the memory of a certain point in time, and it will have no effect on other aspects." ”
