Cyber Heroes

Xiangshan's remaining instinct was frantically warning Xiangshan that this was not a good idea.

"Directly manipulating cellular responses with electrical signals" is not a good idea.

This thing sucks.

It was as if the young scientist was shouting at the mountain, beyond the two-hundred-year-thick barrier of time and space, telling the God of War walking in this world not to do such a thing.

Xiangshan didn't know why he said that. He actually does not have a correct understanding of the extent of his own knowledge. He just felt that this sentence might pose a threat, so he said it naturally.

He instinctively spoke of the most terrifying technical means within his cognition.

After blurting it out, Xiangshan realized how terrible this was.

The electrical signal of nerve cells is generated by the interference of ion pumps on the nerve cell membrane with the flow of charged particles.

External current will also affect the work of the ion pump.

And these ion pumps are not necessarily only affected by current.

The ion pump is essentially a reversible ATPase driven by external energy. And this "external energy" is not only electrical energy. Chemical gradient energy is just as likely as light energy.

Especially light energy.

At the beginning of the 21st century, humans embedded light-sensitive proteins from certain microorganisms into the cell membranes of nerve cells. When these proteins are stimulated by light signals, they induce neural signals.

Humans can control modified mice like gods. Through light signals, humans can make mice go into heat at any time, fall asleep at any time, and eat at any time—and these behaviors will not stop as long as the signal is stopped. Mice will die suddenly due to exercise, eat until they are exhausted, and sleep until their entire body collapses.

As long as humans want to.

An old friend of Xiangshan believes that humans are just machines made of flesh and blood. Proteins and nucleic acids are its system files and storage devices, and the brain is the mechanical operating interface.

So, those things can apply to humans as well.

No...it's not just that...

You can understand it if you think about it carefully.

All cells have a built-in "apoptosis" program. Every cell, including nerve cells, is alive and dead. Without cell apoptosis, the brain's neural network cannot adjust its structure. Without cell apoptosis, every cell in the human body is equivalent to a cancer cell.

Inside every cell, there is a complete set of "apoptosis toolkit" built into it.

Stimulating factors activate the cell receptor-G protein-phosphoinositide system, causing extracellular calcium influx, internal calcium stores, and mitochondrial calcium storage release. The increased Ca2+ then activates a variety of proteases.

Ca2+ and calcium ions play the "button" of the apoptosis program in this process.

Ca2+ ions can enter cells in large quantities through ion channels and ion pumps.

In other words, if technical means can really control ion channels, then humans can completely bypass the cell receptor-G protein-phosphoinositide system, allowing a large influx of extracellular calcium to induce apoptosis...

--No……

Xiang Shan unconsciously pressed his temple with his left hand.

Not only that, if ATP can be replaced by electric field energy, then why can't Ca2+ be replaced by electrical signals?

Yawgmoth's great theory allows humans to do this.

This method... he has seen before.

Saw it a long time ago.

Then, we met three years ago.

——War Supervisor...

After the Eighth Martial God's internal power controlled the rangers and allowed them to attack the commander, the rangers fell into irreversible death.

He should have felt it was against the law at the time...right?

Was it because he had obtained the eighth Martial God in his life and suffered the death of Borshu, so he was not so rational?

Maybe it's due to memory loss?

But Xiangshan is absolutely certain that there is blood behind this technology.

And Xiangshan's inner emotions were completely reflected deep in Suzuki Swift's heart.

The Suzuki Swift feels suffocated.

She obviously should have a collective memory of hundreds of years of murder and arson - these memories are obviously bright and strong, and they have been engraved deep in her soul by technical means.

But even reason, which is most alienated from emotion, tells her that she is facing an abyss.

That is the real abyss. The "desire to dominate others" and the "instinct to obey dominance" that humans received from their ancient ancestors are devouring everything on that side of history. The blood of countless people.

How many people has she killed... How many people has she killed in the village where she lives, which takes pleasure in killing people?

But how many lives and souls are these?

The "modernity" accumulated and transformed from generation to generation from ancient times to the present is also shattered. The more ancient undead exterminate the wandering modern ghosts.

Suzuki Yuyan thought that after she went crazy, she would no longer be afraid. She was not even afraid of death.

But this emotion transcends death.

It is like flame, like ice, like silence, like fury, like night, like curse...

It is like all majestic things, but transcends them.

Suzuki Swift yelled: "This is impossible! It is impossible for electrical signals to be accurately transmitted to specific nerve cells!"

It's one thing to have systems all over the brain start dying at the same time. And fine control is another thing.

Anyone can smash a computer with a stick, but few can learn to program.

Stimulating nerve cells with electrical signals is not a sophisticated technology. Very early on—specifically, in 1791, before neuroscience and psychology were officially born—scientist Luigi Galvani had already used chemical batteries to stimulate the nerves of frogs.

However, after humans learned to embed light-sensitive proteins into the nerve cells of organisms, scientists no longer looked down on this stimulation method.

Electrical signals spread in all directions, while optical signals have strong directivity.

Humans only need to use genetic technology to embed the light-sensitive protein gene into the genome related to specific nerves, and then the light-sensitive protein will automatically appear on the cell membranes of those nerves.

This technology that uses both "light signals" and "genetics" has a simple and straightforward name called "optogenetics."

But as the name suggests, humans must prepare the mice before they are born. No matter what happens, special adenoviruses must be used to transform nerve cells.

Even if this terrifying knight really masters the electrical signals that can control the reaction of nerve cells, he cannot directly affect strangers.

Xiangshan leaned down and whispered in Suzuki Swift's ear: "Silly boy, think about it carefully. Everything was prepared before you were born."

"Even before your mother was born... and before your mother's mother was born."

"The nerve cells in different areas of your brain have different ion pumps on their surfaces. These ion pumps are slightly different and have completely different sensitivities to electrical signals with different contents. Unless most of your ancestors are 'volunteers' I don't know how much genes have mutated in the past two hundred years. However, you can't resist all this, just like you can't resist the curse of 'Turing' or 'Agni'. "

Suzuki Swift clearly realized that this was the truth.
