How does the human brain work? How to identify certain concepts? How do you perceive the world?

Certain neurons in humans respond to specific concepts. In an ideal state, there would be a group of cells in the human brain that specifically respond to the concept of "grandmother" - not "activated when seeing grandmother", but when seeing or thinking of all the things related to "grandmother". ” related things will be activated.

Whether it’s “grandma’s appearance”, “grandma’s cooking taste”, “grandma’s phone call” or even “an old lady who looks like grandma” can activate these neurons.

This hypothesis is called the "grandmother cell" hypothesis. This is the ideal model for the "sparse coding" theory of the brain.

Of course, this is just a metaphor. The human brain is not actually that "theoretical".

But "sparse encoding 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 use "group coding". A group of neurons are activated one after another under a certain concept, forming a "grandmother wearing a brown scarf and playing with her childhood self."

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

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

However, which neuron in the brain encodes which concept is an extremely personal matter. Although the approximate location where a concept is encoded can be limited to a small area of ​​the brain, the neurons encoding the concept may appear at any point within the area.

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

Therefore, each person’s brain neural network is unique. This uniqueness goes far beyond looks, genes or even fingerprints.

Even clones with similar experiences cannot obtain exactly the 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 patterns on the brain-machine barrier, commonly known as "brain patterns", 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, "not exactly the same neurons" may actually be activated, resulting in "different subjective experiences."

However, through language and culture, they can point these "different experiences" to the "same objective concept" during communication.

Two people see reflected light of the same wavelength and obtain perhaps different subjective experiences, but their 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 God of War is actually a special product. She uses special techniques to enhance the coding activity of neurons with electrical signals, and then immerses herself in a memory.

Therefore, many of the concepts encoded in Zhu Xinyu's mind are also encoded in her mind, and have similar positions and orders.

However, the memory she looked at was "facing the mountain" - defined by society and culture as "facing the mountain".

The final result of the encoding is "towards the mountain".

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

From the perspective of Zhu Xinyu's brain, this is "after some special connection specialization and degradation, but it is still basically its own self."

From the perspective of Xiangshan's brain, this is "remembering some mysterious knowledge, but generally he is still himself."

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 the neural network is different from Xiangshan.

Some neurons are weakened and others are strengthened.

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

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

So, in theory...

As long as this difference is made up, the peerless inner power of the Eighth Martial God can come back to anyone.

There is even existing technology for this.

Virtual circuit - using nanoconductors and computers to rearrange the electrical signals in the brain, and change the connection method of "sparse coding" in the hard disk, so that the biological brain can re-output another result.

“Pe…r…so…na!”

Shout to the mountains.

For him, this is the most intuitive "concept" of the "Eighth Martial God" - a personality cover.

Through clear language, Xiangshan sends autosuggestion to his own Saussurean realm.

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

Like a mask "covering" the original spirit.

"hahahahahahahahahahaha……"

C. Shivaji-21 had no idea why the other party suddenly shouted the unpopular term "personality overlay" in such a weird pronunciation, nor did he know why he was so crazy that he suddenly laughed wildly.

--this is a good chance……

C. Shivaji-21 was suddenly confused.

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

It's not "no connection object found", nor "access denied by firewall".

An experience I've never had before.

He had never experienced this feeling in an internal battle.

Completely indescribable.

This sense of alienation...

--happened……

Then he felt a tremor behind him.

A knife struck him.

It should be a knife...right?

He has never had a serious duel with external skills, but it should be like this.

But

a knife? From behind? Cut him?

--Why?

C. Shivaji-21 turned slowly.

One of the rangers slashed him with a sword.

Then, the ranger shook slightly.

The ranger was brain dead just now. This is why C. Shivaji-21 cannot understand this "rebellion".

Attacking the commander on the battlefield will trigger the "War Supervisor Mechanism".

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

However, most of the "self-destruction mechanisms" controlled by intelligent systems can easily be detonated from the outside by internal skill masters, which makes them look stupid.

However, the "War Supervisor" is special. It is an independent system connected only to specific areas in the brain. This system will be triggered when the Ranger appears on the battlefield and "attacks the commander"...no, simulates the thought of "attacking the commander" in his mind. It transmits a special electrical signal to nerve cells.

The ion channels of some nerve cells, including the reticular activating system, are momentarily disrupted.

The brain cannot wake up properly.

At the same time, this signal can also trigger the cell's apoptosis program.

Brain cells throughout the brain will begin to undergo irreversible apoptosis after the subject becomes comatose. No surgery can save it.

This system operates independently and does not accept external information. Even the power source is an independent micro-battery and is only connected to the Ranger's brain. It draws judgment from within the Ranger's own brain.

--Why……

C. Shivaji-21 feels completely incomprehensible.

He couldn't even understand his actions.

He actually flipped off his outer armor, exposing the barrel.

He is also attacking his own people.

--Why……

It shouldn't be like this. Prosthetics connected directly to the brain are difficult to hack, unlike drones. The Rangers themselves also have internal skills. Even if the enemy does hack into their prosthetic body, they can still use their internal strength to resist.

——Am I being controlled?

C. Shivaji-21 is completely incomprehensible. He could clearly feel that... his inner strength was still there. His specialized Saussure domain can still output huge codes instantly.

Then he felt strange.

He was attacked by an internal force. His attacker was Feng Xiao IV. should be.

--but why……

He still didn't understand.

Although the two commanders will not die because of the "combat officer mechanism", there should be no reason for the junior brother to fall out...

But the inner strength suddenly started to work on its own.

Some stimulation drilled into his brain from the input device.

——Ah...ahhh...

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

But C. Shivaji-21 also understood. In his own understanding, this internal force should be directed at the power that controls himself. But the other party didn't know what method he used to graft this internal force to his junior brother.

Presumably Fengxiao IV is in the same situation.

Everyone is in the same situation. The rangers pointed their weapons at their companions and poured bullets into them.

Feng Xiao IV was killed by a white flame spear. The metal jet penetrated his biological brain.

The ranger who took action was also killed by the "War Supervisor" and fell into a state of brain death.

The rangers had fallen to the ground in a mess. According to the judgment of the "War Supervisor Mechanism", most of them participated in the behavior of "surrounding and killing the commander", so they have begun to become brain-dead. There may be a few people whose biological brains are still alive, but they have no fighting ability.

C. Shivaji-21 survived to the end. He defeated everyone who came to him. Several of the rangers who attacked him died from the warlord mechanic. But he also lost the spider-shaped expansion base, and his whole body rolled sideways on the ground like an overturned trash can.

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

--Why……

--what happened……

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

——What is he going to do?

C. Shivaji-21 has almost completely lost the ability to think.

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

Once, twice, three times...

--Why……

C. Shivaji-21 did not figure this out in the end.
