The development of the brain is "high-level functional areas wrapped in low-level functional areas".

In other words, the evolution of the central nervous system is mostly in the outer layer of the "primordial structure", and then a layer of high level structure has evolved. "High level structure" is generally covered with "low level structure".

The most primordial reflex center that regulates the movement of heart blood vessels, breathing, swallowing, vomiting and other important physiological activities.

On top of this, it is to adjust the fiber, correct the movement of the relevant muscles, adjust the joints, and maintain a coordinated movement center for voluntary movements.

The next level includes the nerve center that regulates endocrine and enables high-level thinking activities and emotions to interact.

The next level is the striatum.

This involves the differentiation of the evolution of a species.

In mammals, the striatum is mainly a nerve center that receives signals from the cerebral cortex and thalamus, and regulates movement. It is also responsible for generating "non-declarative memory" [including muscle memory, Memory that is difficult to express with language symbols]. It generally accepts "background information" from the brain.

However, the striatum has been greatly developed on the evolutionary branch of double bows-dinosaurs-birds. For modern birds, the new striatum is enough to support more complex mental activities.

On the other hand, mammals do not work deeply on the striatum. In addition to the striatum, they have evolved a higher level functional area, which is the "neocortex".

For humans, the deeper the nerves, the less important they are-because they are related to the instinct of the body and the brain's ability to direct the fleshy body.

But in the age of prosthetics, these are not important anymore. The biggest advantage of a natural spine is "good quality and low price" and "high cost performance."

In the laboratory, there are better data transmission equipment than the spine.

When the biological brain has suffered some irreversible damage, and the damage will gradually worsen, "abandoning part of the brain" is also an acceptable option.

As long as the new cortex that generates self-awareness is retained, humans can still be considered humans.

This is the minimum.

Of course, this standard is limited to "highly transformed prosthetic people."

For natural persons, those low-level parts basically involve the most basic functions of life support. Injury to the neocortex, amnesia, drastic changes in personality, and insanity are all possible. But if you hurt those primordial parts, you might die directly.

For the prosthetic person, it is "which can't be replaced by mechanization".

Xiang Shan startled: "This...ah, too. Technology can indeed do this step. It should have been this step."

However, this is undoubtedly very Difficult surgery.

Because the neocortex you have to keep is the outermost layer of the brain. And the autonomic nerves and motor nerves that you need to discard are covered by this layer of neocortex.

It's like "don't hurt the skin of an apple, just hollow out the flesh inside" multiplied by one thousand.

Xiang Shan looked towards Tao Enhai: "To what extent are you going to give up? The bottom line?"

"Well, the current technology, in the worst case, can dig into the hippocampus." Tao Enhai thought for a while and shook his head to say with a smile: "There is also a considerable part of the high level cortex that is responsible for movement, sensation, and the like. Theoretically, at least a part of the frontal and temporal cortex is reserved. But to be honest, humans have not yet Thoroughly crack the algorithm of the brain. The frontal and temporal lobes cannot support thinking."

The implication is that the rest can be replaced by mechanization.

"Where is the martial arts cultivation base? The familiarity, acquisition, and selection of complex sports are all related to the striatum. The transformation of long-term memory is in the hippocampus..."

"Yes, if you lose these, you can't remember things with your own mind, and your external skills are also affected. But anyway, there is a hard drive. It's better than death." Tao Enhai shook the head. He stood up again, and grabbed Xiang Shan by the way: "And you... you better explain your real experience. Under the skin of others, I can hardly see you pleasing to your eyes."

" I can tell a little about the matter. But it must be kept strictly confidential." Xiang Shan looked at Tao Enhai: "The data line is directly connected. I only accept this form of conversation."

Tao Enhai was silent for a moment. He said to his dísciple: "Lu Xiu, give me a data cable."

Heard that he does not need immediate surgery, Lu Xiu relaxed a little. He dared not look at his teacher, lowered his head and pulled out a data cable from his waist.

Tao Enhai arched his hands at the other knights: "Sorry, brothers, this matter involves a little bit of the past. I want to talk to this guy alone."

Then, he and Xiang Shan walked into that operating room.

The walls of this operating room are covered with plastic film to isolate it from the soil. This space is very small, only accommodating two or three people, and a small number of instruments have already filled the space. If you want to have an operation, you must bend over and lower your body.

Only the sound of a prosthetic person can perform surgery in such a harsh environment.

Tao Enhai sat on the ground and pointed to the other side.

Xiang Shan also sat down.

Tao Enhai inserted a section of the data cable into the side of his head-if it is a natural person, it should be behind the ear. Xiang Shan inserts the other end of the data cable into his wrist.

[who the hell are you? Tao Enhai asked; [Every guy who claims to be Xiang Shan actually understands that he is not Xiang Shan. They all have their own childhood as the'other' in their hearts. There are few memories of Xiang Shan online now from his childhood. This part cannot be covered. The so-called "Martial God" only agrees more with Xiang Shan's youth memory. You should have that kind of memory. ]

[Tell me, who are you? Speak as your memory. ]

At the moment just now, Tao Enhai confirmed that this guy is a "real personality covering." The signal he transmitted showed the feeling of "internal strength". As of now, internal strength cannot be used on pseudo-personality overlays.

Xiang Shan wanted to smile wryly: [To be honest, I don't have that kind of memory. I also wondered if I was someone else. 】

【Nonsense! ] Tao Enhaidao: [Are you ashamed of that "not the memory of Xiang Shan"? If you really think that you are Xiang Shan, then this idea is shameful! At least the guys who imitate more like-I mean those who are called "Martial God" will not hide this! ]

[No, I’m telling the truth. ] Xiang Shan said so.

He evokes his "first memory that can be traced back"-the memory picked up by Yuki from the garbage dump.

——Blank...Blank...Blank...Water...A little light...

Then the thing about the town of Recycle Bin. The conversation between Julia and the mayor...

[Because it is a direct connection, I can only "hide" and cannot "fiction". ] Xiang Shan said so.

"Fiction" evokes special neural activity. On the emotional level, fictional stories and factual experiences have completely different manifestations.

Perhaps a genius liar can construct a fictional story in an instant, and cannot remain silent on the surface. He can even pretend to be true through "selfless performance" in a short period of time.

But fiction is fiction.

In the case of a stable connection, the internal strength expert can capture this subtle and fleeting performance.

[Is picked up from the garbage dump? This is really a joke. ] Tao Enhaidao: [Are you the protagonist of science fiction comics? ]

[Although it is difficult for me to believe it, this is how it is. ] Xiang Shan said.

[forgive me to speak bluntly, have you been executed by who and put you there after instilling a wrong self-identity? ] Tao Enhaidao: [This is the best explanation I can think of. ]

Xiang Shan unexpectedly nodded: [To be honest, I think this guess is quite convincing. But the problem is, there is no "memory that does not belong to Xiang Shan" in my brain.

[A large amount of redox enzyme can explain it. ] Tao Enhaidao: [You may have the original memory, but it resets when the enzyme restores the brain. 】

Xiang Shan feels that the position of his "chest" has a soft illusion like the touch of foam.

This is "sympathy."

Tao Enhai is "sympathizing" for the unknown people who have suffered "this kind of thing".

Xiang Shan said: [However, there are still doubts. For knights, redox enzyme is a very precious resource. To completely reset an adult's memory, a lot of redox enzymes are needed. Not to mention that after that, I have to engrave Xiang Shan's memory into my brain. If only to punish the "traitor", the knight impossible is so extravagant. ]

[The asylum...not like it. At least the local asylum seekers, only when I appeared suddenly, did not recognize my performance at all. Is this some kind of psychology experiment conducted by the Knight Research Group? And the one with a higher level than the Knight group at the end of Pine Eagle City?

【Ghost knows. ] Tao Enhai is coldly snorted in my heart: [I just hope you don't pretend to be Xiang Shan anymore. ]

[I really have no other memories. 】Xiang Shan said: 【In fact, even Xiang Shan’s youth experience was obtained from other sources. If I don’t think I am Xiang Shan, I don’t know who I am. For the sake of my mental health and avoiding identity confusion leading to mental illness, I tentatively want to call myself this way for a while until I find the memory. ]

[Hmph, it's up to you. ] Tao En Haidao: [But you must remember! You are not Xiang Shan. You are yourself. Don't long for Xiang Shan to be able to take it all together. The freedom and dignity of human beings must rely on themselves to fight for! ]

Xiang Shan said: [By the way, do you need my help for the brain separation operation? From your perspective, your dísciple hope does not seem to be great. 】

In addition to the language level communication, the two sides also exchanged various potential thoughts. As long as the thoughts that appear near the surface of the consciousness can be captured and transmitted by the algorithm.

[You saved a little girl before? You seem to be more troublesome with brain surgery.

[No, Doctor Tao. ] Xiang Shan said: [After seeing you...I remembered it again. Memory about the operation. 】
