Xiangshan's remaining instinct was frantically warning Xiangshan that this was not a good idea.
"Using electrical signals to directly manipulate cellular responses" is not a good idea.
This thing is terrible.
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 didn't 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 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 essence of an ion pump is 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 into the cell membranes of nerve cells. When these proteins are stimulated by light signals, they will induce nerve 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 the signals will not stop, and these behaviors will not stop. Mice
He will die suddenly due to exercise, he will eat until he is exhausted, and he will sleep until his whole 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 cells,
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 the influx of extracellular calcium, the release of calcium from internal calcium stores and mitochondrial stores, and the increased Ca2 in turn activates a variety of proteases.
Ca2, calcium ions act as 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 the apoptosis process...
--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 kind of thing.
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 inner strength 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 a lot of blood behind this technology.
The inner emotions of Xiangshan were completely reflected in the depths of Suzuki Swift's heart.
Suzuki Swift feels suffocated.
She should obviously have a collective memory of hundreds of years of murder and arson - these memories are obviously bright and strong, and have been engraved deep in her soul by technical means.
But even reason, which is most alienated from emotion, is telling 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" that has been accumulated and transformed from ancient times to the present has been shattered. The more ancient undead have eliminated 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 all the brain's systems start dying at the same time. But it's another thing to control it carefully.
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, the scientist Luigi Galvani had already used chemical
The battery stimulated the frog's nerves.
However, after humans learned to embed light-sensitive proteins into biological nerve cells, scientists began to look 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 implies, humans must be prepared before the mice are born. Even if this is not possible, 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. 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.
