Chapter 351

How does the human brain work?How to identify certain concepts?And how do you perceive the world?
Certain neurons in humans respond to specific concepts.In an ideal state, in the human brain, there will be a group of cells that respond specifically to the concept of "grandmother"-not "activated when seeing grandma", but seeing or thinking of everything related to "grandmother". "Relevant things will be activated.

Whether it is "grandma's appearance", "grandma's cooking taste", "grandmother's phone" or even "an old lady who looks like grandma" can activate these neurons.

This hypothesis is known as the "grandmother cell" hypothesis.This is the ideal model for the brain's "sparse coding" theory.

Of course, this is just a metaphor.The human brain doesn't actually "fit theory" that much.

However, "sparse coding in the face of simple abstract concepts" is something that has been able to be observed experimentally.

When faced with complex concepts, the brain will also adopt "group coding", and a group of neurons will be activated successively under a certain concept, forming a "grandmother wearing a brown scarf and playing with herself when she was a child".

When processing sensory information, a layer-by-layer neuron network will perform feature extraction and recognition, like a layer-by-layer filter to filter information for understanding.At the same time, some middle-level neurons that discharge autonomously form a predictive coding structure with the input neurons, so that when the input information meets their own expectations, there is no need for a large number of lower-level neurons to process information, and directly report their own "expectations" to higher-level neurons. The cortex greatly improves the efficiency of encoding and saves precious energy.

And all these neurons may also be actively evoked by autonomous consciousness from top to bottom, forming complex neural activities such as "recall" or "prejudgment".

However, which concept is encoded in which neuron of the specific brain is an extremely personal matter.While the general location where a concept is encoded can be confined to a small area of ​​the brain, the neurons that encode the concept may appear at any point within that area.

What information is encoded by which neuron is related to the personal experience of the coder, and even related to the shape and even the moment of thinking of the coder when learning this concept.

Therefore, each person's brain neural network is unique.This uniqueness far exceeds appearance, genes and even fingerprints.

Even clones with similar experiences cannot get the exact same neural network structure.

The brain-machine barrier formed by special proteins on the outside of the brain is closely related to the structure of the neural network.

The lines on the Brain-Computer Barrier, commonly known as "brain lines", are also unique.

This is also the only basis for the government to register and manage asylum seekers.

It is precisely because of this that when two different people see the same paint, they may actually activate "not exactly the same neurons", thus bringing about "different subjective experiences".

However, through language and culture, they can point this "different experience" to a "same objective concept" in communication.

Two people see reflected light of the same wavelength and have perhaps different subjective experiences, but thoughts can be redirected to the same concept.

However, in rare cases, two people with extremely similar brain neural networks can directly see the "same red".

For example, the Eighth Martial God and Zhu Xinyu.

The Eighth Martial God is actually a special product.Using special techniques, she uses electrical signals to intensify the coding activity of neurons, and then devotes herself to a memory.

Therefore, many concepts encoded in Zhu Xinyu's brain were also encoded in her brain, and they had similar positions and sequences.

However, the memory she watched was "Xiangshan" - defined by society and culture as "Xiangshan".

The final result of encoding is "Xiangshan".

It can be said that although the Eighth Martial God is very close to Zhu Xinyu in terms of cognition of certain specific concepts, the final output of the combination of these concepts is "Martial Ancestor Xiangshan".

In the eyes of Zhu Xinyu's brain, this is "after some special connection specialization and degeneration, but it is still my own self in general".

From the perspective of Xiang Shan's brain, this is "remembering some mysterious knowledge, but it is still his own self in general".

Of course, this is the state of the Eighth Martial God when he "just became Xiangshan".

After several years of practice and several years of fighting, he has become an independent individual, and his neural network is different from that of Xiang Shan.

Some neurons are weakened, while others are strengthened.

In terms of internal strength, the internal strength of the Eighth Martial God is stronger than that of Martial Ancestor Xiang Shan himself.

However, the neuronal network of the Eighth Martial God was developed on the basis of Wuzu Xiangshan. The two are actually very similar, but there are some differences in the circuits.

Well, in theory...

As long as this difference is made up, the peerless internal power of the Eighth Valkyrie can come to anyone again.

There's even existing technology for this.

Virtual circuit—use nano-conductors and computers to rearrange the electrical signals in the brain, change the connection mode of "sparse coding" in the hard disk, and make the biological brain output another result.

"Pe...r...so...na!"

Shout out to the mountain.

For him, this is the most intuitive "concept" of "The Eighth Valkyrie" - a personality mask.

Through clear language, Xiang Shan gave a self-suggestion towards his own Saussure Godland.

The order in the brain is rewritten by the program, and new connections are established.

It is like a mask "covering" the original spirit.

"hahahahahahahahahahaha……"

C. Shivaji-21 didn't understand why the other party suddenly shouted the unpopular term "personality mask" in such a weird pronunciation, and he didn't know why he went crazy and wanted to laugh out loud.

--this is a good chance……

C. Shivaji-21 suddenly became confused.

He felt that his inner strength was like a mud cow sinking into the sea.

Not "No connection object found", nor "Access denied by firewall".

Experience never before.

He had never experienced this feeling in internal strength battles.

Totally indescribable.

This feeling of alienation...

--happened……

Then, he felt a tremor behind him.

A knife fell on him.

It should be a knife... right?

He has never had a serious duel with external skills, but it should have such a touch.

but
a knife?from behind?Cut on him?

--why?
C. Shivaji-21 turns slowly.

A Ranger slashed at him with a sword.

Then, the Ranger flicked slightly.

The Ranger just went brain-dead. This is why C. Shivaji-21 cannot understand this "behavior of mutiny".

Attacking the chief on the battlefield will trigger the "Battle Supervisor Mechanism".

The Rangers have isotope batteries hidden in their bodies and can fight for at least ten years.Even if the martial arts system is flawed, one must be on guard.

It's just that most of the "self-destruct mechanisms" controlled by intelligent systems are easily detonated by internal skills experts from the outside, which seems silly.

However, the "war supervisor" is special.It is an independent system, connected only to specific areas in the brain.When the Rangers appear on the battlefield to "attack sir"...no, when they simulate the idea of ​​"attack sir" in their minds, this system will be triggered.It sends a special electrical signal to nerve cells.

Including the reticular activating system, the ion channels of some nerve cells will be disordered momentarily.

The brain cannot wake up properly.

At the same time, this signal can also trigger the apoptosis program of cells.

The brain cells of the whole brain will start to die after the subject is in a coma, which is irreversible.No surgery can save it.

This system operates independently and does not accept external information. Even the power supply is an independent micro battery, which is only connected to the ranger's brain.It draws judgments from within the Ranger's own brain.

--why……

C. Shivaji-21 felt completely incomprehensible.

He can't even comprehend his own actions.

He actually bounced off the outer armor on his body, exposing the barrel.

He is also attacking his own people.

--why……

It shouldn't be like this.Unlike drones, prosthetics that are directly connected to the brain are difficult to hack.Rangers themselves also have internal skills.Even if the enemy really hacked into their prosthetic bodies, they could still use their internal strength to resist.

——I was controlled?

C. Shivaji-21 is completely incomprehensible.He could clearly feel...his internal strength is still there.His specialized Saussure God's Domain can still output huge codes instantly.

Then, he felt a strange feeling.

He was attacked by an internal force.The person who attacked him was Feng Xiao IV.should be.

--but why……

He still didn't want to understand.

Although the two commanders will not die suddenly because of the "supervisor mechanism", but the junior should have no reason to turn their faces...

But the inner strength suddenly worked on its own.

Some kind of stimulus drilled into his brain from the input device.

——Ahhhhhhhhhhhhhhh

Like a conditioned reflex, C. Shivaji-21 was completely unable to control his thoughts.He broke out in a long-simmering revolt.

But C. Shivaji-21 got it too.In my own cognition, this internal force should be directed at the power to control myself.But the other party didn't know what method he used to graft this internal force onto his junior brother.

It must be the same situation with Fengxiao IV.

Everyone is in the same state.The rangers greeted their comrades with weapons and poured bullets on them.

Feng Xiao IV was killed by a white firework spear.Jets of metal pierced his biological brain.

And the ranger who attacked was also killed by the "war supervisor" and fell into a state of brain death.

The Rangers have fallen to the ground in a mess.According to the judgment of the "War Supervisor Mechanism", most of them participated in the behavior of "siege and kill the chief", so they have already begun to be brain-dead.Maybe there are still a few people whose biological brains are still alive, but they have no fighting power.

C. Shivaji-21 survived to the end.He beat everyone who came to him.Several of the rangers who attacked him were killed by the Overseer mechanic.But he also lost the spider-like extension base, and his whole body rolled over on the ground like a fallen trash can.

C. Shivaji-21 struggled to turn the prosthetic eye.

--why……

--what happened……

He saw that terrible knight stood up.The knight pressed his hand on his forehead, which seemed to be in great pain.He randomly picked up a weapon dropped by a ranger from the ground - a long gun, and walked to C Shivaji-21.

——What is he going to do...

C. Shivaji-21 is nearly completely incapacitated.

He watched the knight pick up the metal rod and smash it down.

One, two, three...

--Why……

C. Shivaji-21 didn't figure it out in the end either.
