Cyber Heroes

Xiang Shan’s remaining instinct is madly admonishing Xiang Shan that this is not a good idea.

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

This thing is terrible.

It is like the young scientist Xiang Shan, roaring beyond the barriers of time and space that is two hundred years thick, tells Martial God walking in this world not to do this kind of thing.

Xiang Shan doesn't know why he said that. He actually didn't have a correct understanding of the degree of his own knowledge. He just thought that this sentence might pose a threat, so he said it naturally.

He instinctively generally said the most terrifying technical means in the cognitive range.

After blurting out, Xiang Shan realized how terrifying this is.

The electrical signals of nerve cells are produced by the interference of the flow of charged particles by the ion pump on the nerve cell membrane.

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

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

Ion pump is essentially a reversible ATPase driven by external energy. And this "external energy" is not only electrical energy. Chemical gradient energy is as possible as light energy.

Especially light energy.

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

Humans can manipulate modified mice like gods. Through light signals, humans can make mice come into estrus at any time, fall asleep at any time, eat at any time-and the signal will not stop, these behaviors will not stop. The mice will die suddenly, will eat to death, will sleep until the whole body is exhausted.

As long as humans want.

An old friend of Xiang Shan believes that people are just machines made up of flesh and blood. Protein and nucleic acid are its system files and storage devices, and the brain is the mechanical interface.

So, those things can also be applied to humans.

No...not just that...

If you think about it, you can understand.

All cells have built-in "apoptosis" programs. Including nerve cells, every cell 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 a cancer cell.

In every cell, there is this complete set of "apoptosis toolkit" built in.

Stimulating factors activate the cell receptor-G protein-phosphoinositide system, causing extracellular calcium influx, internal calcium storage, and release of calcium storage in mitochondria. Increased Ca2+ activates a variety of proteases.

Ca2+, calcium ions act as the "button" of the apoptotic 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, and then induce Apoptosis program...

——No...

Xiang Shan unconsciously pressed his left hand on his temple.

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

Yoggmov’s great theory allows humans to do this.

This method...he has seen it.

I saw it a long time ago.

Then, I saw it three years ago.

——Supervisor...

The internal strength of the Eighth Martial God controls the rangers. After the rangers attack the commander, the rangers fall into irreversible death. Among.

At the time, he should feel that it was a violation of peace... right?

At that time, he won the eighth Martial God's life, and suffered the death of Borshu, so is it not so sensible?

Perhaps because of lack of memory?

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

And Xiang Shan's inner emotions are fully presented in Suzuki Swift's deep in one's heart.

Suzuki Swift felt suffocated.

She obviously should have a collective memory of several hundred years of murder and arson-obviously these memories are bright and strong, and they have been carved into the depths of her heart by technical means.

But even the most alienated reason is telling her that she is facing the abyss.

That is the real abyss. The "desire to dominate others" and the "instinct to obey dominance" that mankind got from the ancient ancestor first swallowed 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 was for pleasure?

But how many lives and souls are there?

The "modernity" accumulated and transformed from ancient times to the present has also shattered. The Ancient Death Spirit eliminated the wandering modern ghosts.

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

But this emotion is beyond death.

It is like flames, ice, silence, fury, night, and curse...

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

Suzuki Swift roared: "This is impossible! The electrical signal impossible is accurately transmitted to specific nerve cells!"

It is one time for the whole brain system to start apoptosis at the same time. thing. And fine manipulation is one thing.

Anyone can smash a computer with a stick, but only a few people can learn to become.

Simulation of nerve cells with electrical signals is not a sophisticated technique. At a very early time—specifically, in 1791, when neither neuroscience nor psychology was officially born, scientist Luigi Galvani used chemical batteries to stimulate the nerves of frogs.

However, after humans have learned to embed light-sensitive proteins into biological nerve cells, scientists no longer appreciate this kind of stimulation.

The electrical signal spreads towards all directions, while the optical signal has a strong directivity.

Humans only need to use genetic technology to insert 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 signal" and "genetics" has a simple and straightforward name called "optogenetic".

But as the name suggests, humans must be prepared before mice are born.

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

Xiang Shan leaned down and whispered in Suzuki Swift’s ear: "foolish child, think about it carefully. Before you are born, everything is ready."

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

"There are different ion pumps on the surface of nerve cells in different areas of your brain. These ion pumps are slightly different , Has completely different sensitivity to different content of electrical signals. Unless your ancestors, most of them are'volunteers' or'first period' people. I don't know how much genetic mutation has been made 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 realizes that this is the truth.
