Chapter 494 Xiangshan Gradually Understood

Chapter 494 Xiangshan gradually understood...

Xiangshan's remaining instincts frantically warned Xiangshan that this was not a good idea.

"Using electrical signals to directly control cell reactions" is not a good idea.

This matter is terrible.

It was as if the young scientist Xiangshan was screaming outside the two-hundred-year-old barrier of time and space, telling the martial god walking in the world not to do such a thing.

Xiangshan didn't know why he said that. He didn't actually 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 his cognitive scope.

And after blurting it out, Xiangshan realized how terrible it was.

The electrical signals of nerve cells are generated by the ion pumps on the nerve cell membrane interfering with the flow of charged particles.

And the external current will also affect the work of the ion pumps.

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

The essence of the ion pump is a reversible ATP enzyme driven by external energy. And this "external energy" is not only electrical energy. Chemical gradient energy is as likely as light energy.

Especially light energy.

In the early 21st century, humans embedded light-sensitive proteins in certain microorganisms into the cell membranes of nerve cells. These proteins will induce nerve signals when stimulated by light signals.

Humans can control modified mice like gods. Through light signals, humans can make mice estrus, sleep, and eat at any time - and these behaviors will not stop as long as the signals are continuous. Mice will die suddenly from exercise, eat until they are full, and sleep until their whole body fails.

As long as humans want.

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 operating interface of the machine.

So, those things can also be used on humans.

No... not just that...

Think about it carefully and you will understand.

All cells have a built-in "apoptosis" program. Including nerve cells, every cell has life and death. 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.

Every cell has a built-in "apoptosis toolkit".

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

Ca2+, calcium ions play the role of the "button" of the apoptosis program 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 extracellular calcium to flow in large quantities, and then induce apoptosis...

-No...

Xiangshan 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 it before.

He saw it a long time ago.

Then, he saw it three years ago.

- War Supervisor...

The Eighth Martial God's inner strength controlled those rangers and made the rangers attack the commander, and then those rangers fell into irreversible death.

He should have felt uncomfortable at that time... right?

Was it because he had obtained the life of the eighth martial god and encountered the death of Borshu, so he was not so rational?

Perhaps it was because of the loss of memory?

But Xiangshan was absolutely sure that there was blood behind this technology.

And Xiangshan's inner emotions were fully reflected in the depths of Suzuki Yuyan's heart.

Suzuki Yuyan felt suffocated.

She should have a collective memory of murder and arson for hundreds of years - these memories were bright and strong, and were engraved in the depths of the soul by technical means.

But even the rationality that was most alienated from emotions told her that she was facing the abyss.

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

How many people did she kill... The village where she lived took pleasure in killing people, so how many people did she kill?

But how many lives and souls were these?

The "modernity" that has been accumulated and transformed from ancient times to the present has also been shattered. The older dead spirits have eliminated the wandering modern ghosts.

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

But this emotion transcends death.

It is like flames, like ice, like silence, like rage, like darkness, like curses...

It is like all solemn things, but it transcends them.

Suzuki Yuyan shouted: "This is impossible! Electrical signals cannot be accurately transmitted to specific nerve cells!"

It is one thing to make the whole brain system begin to die at the same time. And it is another thing to manipulate it precisely.

Anyone can smash a computer with a stick, but only a 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 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 living creatures, 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, specialized 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, just like you can't resist the curse of Turing or Agni. "

Suzuki Swift clearly realized that this was the truth.
