Chapter 494 Xiang Shan Gradually Understands...

Xiang Shan's remaining instincts are frantically warning Xiang Shan that this is 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 Xiangshan shouted outside the 200-year-old barrier of time and space, telling the warriors walking in this world not to do such things.

Xiang Shan didn't know why he said that.In fact, he did not have a correct understanding of the extent of his knowledge.He just felt that this sentence might pose a threat, so he said it naturally.

He instinctively said the most terrifying technical means within the scope of cognition.

After blurting it out, Xiang Shan realized how terrible it 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.

The external current will also affect the work of the ion pump.

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

The essence of the ion pump is a reversible ATPase driven by external energy.And this "external energy" is not only electric 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 in some microorganisms on the cell membrane of nerve cells.These proteins, when stimulated by light signals, induce nerve signals.

Humans can manipulate modified mice like gods.Through light signals, humans can make mice come into heat at any time, sleep at any time, and eat at any time-and the signals will not stop, and these behaviors will not stop.Mice will suddenly die from exercise, eat until they are full, and sleep until they are completely exhausted.

As long as humans want to.

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

So, those things can be applied to humans as well.

no...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 the apoptosis of cells, 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 whole set of "apoptosis toolkit" built in.

Stimulant factors activate the cell receptor-G protein-phosphoinositide system, causing extracellular calcium influx, internal calcium storehouses, and the release of calcium stored in mitochondria. The increased Ca2+ then activates a variety of proteases.

Ca2+, calcium ions act as the "button" of the apoptosis process in this process.

Ca2+ ions can enter the cell 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, and then inducing the apoptosis process...

--Do not……

Xiang Shan unconsciously pressed his temple with his left hand.

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

Yawgmoth's great theory made it possible for humans to do this.

This method...he has seen it before.

Saw it a long time ago.

Then, I met three years ago.

——War Supervisor...

The internal strength of the Eighth Valkyrie controlled the rangers, and after the rangers attacked the chief, those rangers fell into an irreversible death.

He should have felt that it was against harmony at that time... right?

It was the life of the Eighth Valkyrie at that time, and the death of Borshu, so it was not so rational?

Maybe it's because of memory loss?

But Xiang Shan is absolutely sure that there is dripping blood behind this technology.

And Xiang Shan's inner emotions were fully presented to the depths of Suzuki Swift's heart.

Suzuki Swift felt suffocated.

She obviously should have a collective memory of killing and arson for hundreds of years-it is clear that these memories are bright and strong, and they have been engraved deep in her heart by technical means.

But even reason, most alienated from emotion, told her that she was facing the abyss.

That is the real abyss.The "desire to dominate others" and the "instinct to obey domination" that humans have acquired from their ancient ancestors devour everything on the other side of history.The blood of countless people.

How many people did she kill... How many people did she kill in the cottage where she lived?
But how many lives and souls are these?

The "modernity" that has been accumulated and transformed from generation to generation from ancient times to the present is also shattered.The older undead wiped out the wandering modern ghosts.

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

But this emotion goes beyond death.

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

It is like all sublime things, but transcends them.

Suzuki Swift roared: "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 apoptotic at the same time.And fine manipulation is another thing.

Anyone can smash a computer with a stick, but very few people 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 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 looked down on this kind of stimulation.

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

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

This technology, which uses both "optical signal" and "genetics", has a simple and straightforward name called "optogenetics".

But as the name suggests, humans have to be ready before the mice are born.No matter how bad it is, special adenoviruses must be used to transform nerve cells.

Even if this terrifying knight really mastered the electrical signals that can control the response of nerve cells, he can't directly act on strangers.

Xiang Shan leaned down and whispered in Suzuki Swift's ear: "Silly boy, think carefully, everything was prepared before you were born."

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

"Nerve cells in different areas of your brain have different ion pumps on the surface. These ion pumps have subtle differences and have completely different sensitivities to electrical signals of different content. Unless your ancestors, most of them are 'voluntary I don't know how much the genes have mutated in the past 200 years. But 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.
