Chapter 248 Communication

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

In other words, the evolution of the central nervous system is mostly in the outer layer of the "primitive structure", and then evolved a layer of advanced structure. "High-level structures" generally cover "low-level structures".

The most primitive, the reflex center that regulates important physiological activities such as cardiovascular exercise, breathing, swallowing, and vomiting.

On top of this, it is the motor center that performs fiber adjustment, corrects the movement of relevant muscles, adjusts joints, and keeps voluntary movements coordinated.

And the higher level includes the nerve center that regulates endocrine and enables high-level thinking activities and emotions to interact with each other.

And the next layer is the striatum.

This involves the differentiation of a species evolution.

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

However, the striatum has been greatly developed in the clade of diarchs-dinosaurs-birds.For modern birds, the neostriatum is sufficient to support more complex mental activities.

Mammals, on the other hand, do not deeply work the striatum.In addition to the striatum, they have evolved a layer of higher functional areas, which is the "neocortex".

For human beings, the deeper the nerves, the less important they are—because they are related to the instinct of the body and the ability of the brain to direct the body.

But in the age of prosthetics, none of that matters.The biggest advantage of natural spine is "high quality and low price" and "high cost performance".

Within a laboratory, there exists a better data transmission device than a spine.

And when the biological brain has suffered some kind of irreversible damage, and the damage will gradually deteriorate, "abandoning part of the brain" is also an acceptable option.

As long as the neocortex that generates self-awareness is preserved, people can still be regarded as people.

This is the bare minimum.

Of course, this standard is limited to "high transformation rate prosthetics".

For natural people, those low-level parts are basically involved in the most basic functions of life support.Injury to the neocortex, memory loss, dramatic personality changes, and insanity are all possible.But if you hurt those original parts, you might die directly.

For prosthetics, it is "which one cannot be replaced by mechanization".

Xiang Shan was stunned: "This...ah, yes. Technology can indeed achieve this step. It should have come to this step."

However, this is undoubtedly a very difficult operation.

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

This is like multiplying the difficulty of "hollowing out the pulp inside without hurting the skin of the apple" by a thousand.

Xiang Shan looked at Tao Enhai: "How far 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, shook his head and smiled: "A considerable part of the high-level cortex is also responsible for movement and sensation. Theoretically, the minimum is 'reserve Part of the frontal lobe and temporal cortex'. But to be honest, humans have not completely cracked the algorithm of the brain. The frontal lobe and temporal lobe cannot support thinking."

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

"What about martial arts? The familiarity, acquisition and selection of complex movements are all closely related to the striatum. The transformation of long-term memory is in charge of the hippocampus..."

"Yes, if you lose these, you won't be able to remember things with your own brain, and your external skills will also be affected. But at least there is still a hard drive. It's better than dying." Tao Enhai shook his head.He stood up again, and grabbed Xiang Shan by the way: "And you... You'd better tell your real experience. Wearing someone else's skin, it's hard for me to see you pleasing to the eye."

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

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

Hearing that he didn't need immediate surgery, Lu Xiu was slightly relieved.He didn't dare to look at his teacher, he lowered his head and pulled out a data cable from his waist.

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

With that said, he followed Xiang Shan into the operating room.

The walls of this operating room are covered with plastic film to isolate it from the dirt.This space is very small, it can only accommodate two or three people, and a small number of instruments have filled the space to the brim.To perform surgery, you must bend over and lower your body.

Only prosthetic doctors can perform operations in such a harsh environment.

Taue Enhai sat on the ground and pointed to the opposite side.

Xiang Shan also sat down.

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

【Who are you? 】Tao Enhai asked in this way; 【Every guy who claims to be Xiang Shan actually knows that he is not Xiang Shan.They all have their own childhood as an 'other' in their hearts.There are very few memories of Xiangshan online now from his childhood.This part cannot be covered.The so-called "War God" only agrees more with Xiang Shan's youthful memories.You should have that memory too. 】

[Tell me, who are you?Speak with the identity of your memory. 】

At that moment just now, Tao Enhai was sure that this guy was a "true personality mask".The signal he transmitted showed the feeling of "internal strength".As of now, the false personality mask cannot use internal strength.

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

[Nonsense! 】Tao Enhai said: 【Are you ashamed of that "memory that wasn't Xiangshan"?If you really think that you are Xiang Shan, then this idea is shameful!At least the guys who are more alike - I mean the ones called "Valkyrie" won't hide it! 】

[No, what I said is the truth. 】 Xiang Shan said so.

He recalls his "first memory that can be traced back" - the memory of being picked up by Yuki from the junkyard.

—blank...blank...blank...water...a little light...

Then there's the recycle bin town thing.Yulia's conversation with the mayor...

[Because it is directly connected, I can only "conceal", but not "fictitious". 】 Xiang Shan said so.

"Fabrication" evokes specific neural activity.On an emotional level, fictional stories play out very differently from factual experiences.

Perhaps a con artist with genius can construct fictional stories in a split second, and keep it on the surface.He can even pretend it's real for a short time by "acting with ecstasy".

But fiction is fiction.

In the case of a stable connection, a master of internal skills can capture this subtle performance that is fleeting.

[Picked up from the garbage dump?What a joke. ] Tao Enhaidao: [Are you the protagonist of a science fiction comic? 】

[Although it's hard for me to believe it, that's how it is. 】 Road to the mountain.

【With all due respect, have you been executed by someone and put there after instilling a wrong self-identity? 】Tauen Haidao: 【This is the best explanation I can think of. 】

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

[A large amount of redanase can be explained. 】Tao Enhai said: 【You may have the original memory, but it was reset when Huandan enzyme restored the brain. 】

Xiang Shan felt a soft, bubble-like illusion in the position of his "chest".

This is "sympathy".

Tao Enhai was "compassionate" for the unknown people who suffered "such things".

Xiang Shan said: [However, there are still doubts.For knights, Huandan enzyme is a very precious resource.To completely reset the memory of an adult, a lot of redanase is needed.Not to mention that after that, Xiangshan's memory had to be engraved into my brain.If it is only for the execution of "traitors", knights cannot be so extravagant. 】

[The asylum... is not like that either.At least the local asylum seekers only thought that I appeared suddenly and didn't recognize me at all.Could this be some kind of psychological experiment by the Knights of Science?And the one with a higher level than the Mana Knights of Pine Eagle City? 】

[Ghost knows. 】Tao Enhai snorted coldly in his heart: 【I just hope you stop pretending that you are Xiang Shan. 】

[I really don't have any other memories. 】Xiang Shan said: 【In fact, even Xiang Shan's youth experience, I got it from other sources.If I don't think of myself as Xiang Shan, I don't know who I should be.For the sake of my own mental health and to avoid mental illness caused by identity confusion, I still want to call myself this way for a while until I find my memory. 】

【Hmph, whatever you want. 】Tauen Haidao: 【But you must remember!You are not Xiangshan.You are yourself.Don't expect Xiangshan to do everything.The freedom and dignity of human beings must be fought for by the current self! 】

Xiang Shandao: [By the way, do you need my help for the brain separation operation?From your perspective, your disciple's hopes don't seem to be very great. 】

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

【You saved a little girl before?You seem to have trouble with brain surgery. 】

【No, Doctor Tao. 】Xiang Shan said: 【After seeing you... I remembered it again.Memories of surgery. 】
