The development of cranial nerves is not simply the more the better.

In fact, the "maturation" of the brain nervous system is a process of "subtraction".

The primitive state of the brain is a primitive network where all nodes have the same weight. Later, along with people's daily activities, some of the neuronal connections are used more frequently, while others are less frequent.

And the more this is the case, the more weight the "used" connections will have. And those that are hardly used will be weighted even lower.

Then, the high-weight connecting pathways will be further strengthened, and even special "protective sheaths" will appear, forming a mature "loop", and it will be fixed.

and those that are not used frequently will regress.

The connecting pathways of neurons are equivalent to being "specialized".

In the process, humans learn to walk, learn to use their hands, and learn to speak......

This is also the reason why after a long period of not speaking, the person becomes "dumb" - his circuit responsible for "speaking" subsides on its own. He forgot to speak.

It is generally believed that "learning" is a process that inhibits unnecessary information input channels and strengthens the ability to perceive target information. This inhibition and intensification is naturally dynamic.

A certain enzyme can reverse the physiological cycle of neurons within a certain range, so that the neural network can return to its original state and prepare for secondary development.

It's not about renewing cells, it's just about reversing the circular's cycle.

Xiang Shan even remembers that at the beginning of the birth of this technology, it was considered by humans to be "an epoch-making technology that expands the potential of the brain", and it was considered a prelude to superhuman upheaval.

However, this technique quickly fell out of the woods, and eventually it was only used in areas such as neurosurgery, psychology, and congenital intellectual disability reconstruction.

The simple reason is that there are so many things that this enzyme can forget, and the time it takes to retrain is very expensive.

It is almost impossible for human beings to rely on this technology to create people who are beyond human intelligence.

It was not until the popularization of metal-based proteins and prosthetic technology.

Thanks to the memory storage device, you can store your memories on the hard disk and expand the capacity of the brain.

But it is generally believed that this is very cost-effective.

After all, for most people, there's no difference between storing memories on a hard drive and storing them in a biological brain. If you want to learn a new technology, then you can use a hard disk storage. All you need to pay for is the little thing that "adapts your information to the hard drive with your biological brain".

Only one point.

The biological brain and the Turing machine may not be the same, and there is no point in common between the two. No matter how good the internal skills are, it is impossible to dig out the information in the brains of human creatures.

However, the information in the hard disk, in the face of real masters, can be deleted and tampered with at will.

"Remember the thing I told you to kill with your biological brain?" Xiang Shan looked at Yuki: "Anything recorded on the hard drive, it can be taken away." At least, the biological brain is incomprehensible until humans truly decipher the mysteries of the brain. ”

Xiangshan was prepared early on.

But there is still a major difficulty in this problem.

In the late 40s and early 50s, after the birth of brain hard disk technology, neurologists measured and determined that the human brain capacity was about 2.5 petabytes after transcribing it into a format that the hard disk could store.

2.5PB, about 2560TB, or 2621440GB. It stands to reason that this should be able to hold all the text materials in several libraries.

Unfortunately, humans can't store their knowledge in formats like TXT, PDF, etc.

When humans perceive an event from the outside world, they generate a series of memories. The memory of "a specific event" is divided into "the information received by the senses in this event", "the emotional memory of this event", "the knowledge brought by this event", etc., which are stored in different parts of the brain.

In many cases, it is not all "knowledge" that occupies the memory space.

But if you rely on things like reverse growth enzymes and neurosurgery, Xiang Shan can change this slightly.

He transferred all the memories that could be transferred to the hard drive. Subsequently, he used that reverse growth enzyme on his brain, washing away what his brain already had, retraining his biological brain, and jot down more knowledge.

All he has now is all the knowledge he needs to "start from scratch."

What twists and turns have you experienced? What kind of blood and sweat did he put in in the process of "retraining"?

Xiang Shan doesn't remember anything, and it is impossible to remember. Even this process was speculated by him based on his own "knowledge". He himself has no memory, and he doesn't remember this for a long time.

If he didn't get those memories back, he would never be able to remember them himself.

He also can't remember what he's been through. He can only judge whether he empathizes with this memory and whether it is something he has experienced by "whether this memory matches the emotional memory in his mind".

That being said......

Xiang Shan didn't expect that he would be physically robbed of all his memories.

This should only be a means to prevent hackers.

Why? He's fallen to that point, and it's easy for the enemy to kill him if he wants.

But in any case, he did fall into the worst situation he could imagine.

In his biological brain, there was only pure technology left, and the "passion" that was limited to technology at that time and could not be accurately transformed.

He didn't know how the technology was used, or what kind of action that passion should be used to drive it.

Everything was conjectured by himself.

From this technique, he deduced what he had done before, and what the fire of passion should burn.

"I was ready for the past. I know everything about that. He's who I am, and I just have a little less memory than him. Xiang Shan squatted beside Yuki and looked into the distance: "I know a lot of things...... He knows more than I am. And our emotions are aligned. So, I trust the decisions I made in my past self – how could I betray my past self who knew everything? ”

Yuki exclaimed, "But Master, you also know what you didn't know in the past, right?" You didn't know me or anyone here......"

Xiang Shan pressed his palm on Yuki's head: "Okay, what to do, I decided in the past." This will never change. If you want to learn the last thing from me for the rest of your days, ...... Come here around this time. Of course, it's okay if you don't come, but remember to format the drive I gave you after I'm gone......"

Before Xiang Shan could speak, Yuki left in a huff.

Xiang Yamamoto wanted to stop him for a few words, but finally shook his head and laughed out loud.

"This guy ......"

He stood on a mountain of garbage, on the wreckage of a battleship, and looked into the distance. Endless garbage. Twisted metal covers the earth. Further afield, there is a small town that is not much different from the garbage dump. At the end of the line of sight, on the horizon, a silvery gray plant rolled up in the wind.

Sometimes he wondered how old he was before he lost consciousness. He felt that he should still be a young man. But he seems to have experienced a lot of similar "partings".

"Tsk, if I haven't lost my memory, I won't believe that I would have a trace of ...... in such a garbage dump-like place Attachment and a sense of belonging? How does the fledgling effect work? ”

However, for knights, this may be a common thing.

………………………………………………

For the next ten days, Xiang Shan did not see his disciples.

………………………………………………

In a two-dimensional world, a small man is carefully jumping to dodge oncoming turtles and missiles falling from the sky.

A wave of chemical energy welled up in the neurons of the Apennines. Even the brain's electrical system, which assists in reflexes, is working.

This is one of the hardest traps of this game. There is only one frame of reaction time. And the number of action frames of each action of this villain is greater than one frame. You have to "anticipate" this trap before it takes shape. In this "one frame", the villain you control must reach the only safe "point" in the entire field of vision......

——An old martial artist said that there is a secret of the game of external skills.

"Bang"!

At this moment, a flickering icon suddenly appeared in the field of vision. Since this "alert system" takes precedence over the game, the computer has a lag that shouldn't be there.

The head of the two-dimensional villain grazed the missile.

Collision Judgment ...... Fail.

The villain fell into a bottomless abyss of despair.

The Apennines, on the other hand, cut off the progress of the game and calmly reflected on the gains and losses. He shouldn't be angry at this time, because this situation is also likely to appear in a fight. There should be no excuses for any failure.

This is a kind of martial arts training. Today's martial artists have always used various means to explore the origin of martial arts, trying to understand martial arts from the perspective of technical history. And there is a saying that the earliest martial arts ideas are "games" from the old humans.

Then, with a ding, one by one, the brain and the spine exited from a black box-like host and fell into the prosthetic body where the skull was separated directly below. The spine twisted twice like a snake, and found the right interface. Then the skull closes.

The game of the old humans, for modern warriors, of course, cannot be played with prosthetics. In the case of strategy games, if it is an action game, the reaction mechanism built into the driver chip will bypass the brain and operate the prosthetic body with something similar to a "script".

For modern warriors, the speed of the "hand" is simply too fast.

Nerve signals as fast as the maximum speed of one second and 100 meters cannot catch up at all.

To do this kind of training on the "way of martial arts", you have to get rid of your prosthetic body and use your brain to feel the "challenge" of the game.

This prosthesis was commonly used in the Apennines. It is a prosthetic body for reproduction, and apart from the brain, only the reproductive system is still an organism. This embodiment is proof that their asylum bearers have fulfilled their "obligation to preserve genetic diversity". Of course, the artificial skin with adjustable sensitivity also allows this prosthesis to be used for entertainment when it is free.

But the Apennines did not like the kind of "entertainment" that was full of obligations at all. He is a little more interested in this kind of dance training now.

The secretary was on the side.

Apennines naturally remembered the events of more than half a month ago. He looked at the secretary and asked, "How is the 'mountain' that I called your attention to before?" ”
