? "Our brain has EEG active at all times. Every neuron in the brain has a voltage. When ions flow in and out of the cell, the voltage will change, which in turn will stab the neighboring neurons to make them. There are also changes. Many cells can generate EEG at the same time. There are many different frequencies of the brain that propagate in the brain, which can be divided into different segments, called a, β, theta, and γ."

In the hive laboratory, Jenny is leading Catherine to introduce her latest scientific and technological achievements here.

With a repair protein like a cheater, all biotechnology is advancing by leaps and bounds, and it is also very advanced compared to the original world.

"But does this have anything to do with this robotic arm?"

Catherine was still looking at the robotic arm.

The bones of this arm are the kind of black bones previously studied. Although it is a mechanical arm, it looks like plastic.

"Of course it matters. EEG can perfectly organize the various information we feel. Different frequencies of the brain correspond to different spike signals, so that neurons can be aligned to the channel and focus on their own tasks without interference. EEG also plays a role in synchronizing neurons. Different signals from a stab source can be processed in different areas of the brain and can be recombined into a whole under the synchronization of EEG."

Jenny explained to Catherine: "This is also the basis of our research. We have obtained our final series of studies based on this stinging signal, and the result of this research is that we can use the human brain to control the robotic arm... "

"Moreover, I have already done research on Rebecca."

"What did you study?"

Jenny took Catherine to see Rebecca, who was still a test subject.

Rebecca was naked, but Catherine clearly noticed that Rebecca's hands below the elbows were gone, instead, there were two mechanical palms.

"I implanted optical fibers into Rebecca's brain. I used light to command life. As the light changes, I can learn how neural connections work. This technique is used to depict a detailed picture of the brain. Neural connection diagrams are used in medical and brain science research... The brain functions through the multiple connections of a large number of neurons. It was impossible to know how they operate in detail in the past. But my method provides the possibility for this."

Jenny was a little excited.

"Similarly, through this optical fiber, Rebecca can use her body to control this limb of her body."

"By connecting the brain and the artificial limb, the amputee can use the prosthesis like his torso. This is the final result of my technique!"

Jenny announced her research curiously.

"..."

Catherine didn't respond.

"...Aren't you moving?"

The fanatical Jenny felt a little strange after discovering that Catherine didn't seem to be moving.

"I'm not a Frankenstein!"

Catherine rolled her eyes, oops. She felt a little twitching in her eyes.

"Speaking of which, being able to control artificial limbs is not the research we have been making breakthroughs... It is always difficult to surprise people with what is expected..."

Catherine shook her head.

"Is that right?"

Jenny frowned.

"What you see is just the tip of the iceberg! I want you to see how far my research is!"

Jenny was obviously not convinced, and then Jenny took Catherine to another part of the laboratory, where many guinea pigs were kept.

But these little white mice are a little strange, some strange things are installed on their heads. These mice were resting listlessly at this time. "By connecting the fiber to the mouse's brain. I have been able to accurately control the specific behavior of the mouse with a specific length of visible light-just like this!"

Jenny lifted a mouse out and put it on the other side.

Catherine noticed a few led lights.

Jenny let the blue light come on, and the mouse suddenly. He started to run in a crazy circle, turning his head, and didn't seem to know he was tired. For five minutes, the mouse kept running, until Jane turned off the light, the mouse returned to normal, and then gasped.

"I can also use blue light to control the contraction rhythm of mouse cardiomyocytes to synchronize it with the blue light strobe. I call this technology light stab genetic engineering-Kate, what do you think."

"Al-n-plus--ng (light thorn genetic engineering)?."

Catherine was really shocked this time, she even couldn't believe it.

"Yes, this technology combines various technologies such as microbiology, modern genetics, neuroscience, and bioengineering science. It achieves the directional control of special cell activity. This is the basis of my technology."

Jenny said: "Towket, your blessing, I can study the changes in the physical condition of life forms in some extreme situations, which has brought a huge guarantee to my research.

"How did this happen?"

Can control the body of mice now, will it be possible to control the human body in the future?

Catherine felt that this technique was not to be underestimated.

"Microbial opsins-that is, light-sensitive ion channels. This is not my research, it was discovered by someone. They found that these proteins are like light-controlled switches. They can be exposed to a specific length of light-most commonly visible light blue light. , Yellow light-live or inhibit, change the cell membrane ion channel activity, and thus the cell activity also changes."

"After that, they separated the gene encoding the corresponding opsin from the algae DNA, and added a specific promoter to it, which can be understood as a switch, and then loaded into the corresponding virus; then the virus was injected through the intracerebral localization injection technique. Enter the specific part of the brain of the experimental animal and connect the optical fiber. At this point, you are done, and the light-controlled switch is installed. Only when the microbial opsin is specifically expressed in the infected neuron, the miracle can be witnessed..."

Jenny is quite proud.

"The result was researched by others...?"

Right, Jenny is not Einstein, she has so many researches at hand, and she is still thinking about genetic research?

"Um...I provided the condition, and I suggested that they use repair protein, otherwise these mice would have died..."

"And, Kate, don't you think this is a great study?"

"I always feel that something terrible will happen..."

Catherine always felt a little guilty.

"Drug injection, electric puncture, etc. can also change cell viability. However, the effect of drug injection is mostly systemic, but all cells with drug receptors will be affected by the drug; even with the aid of technical means such as positioning injection, The cells around the injection site may also be affected by the drug. The same is true for electric spurs. It is difficult to ensure that only the same type of neuron cells receive electrical spur signals. If the intertwined and complicated neurons are compared to the hidden criminals-target neurons- In the case of a crowd of people, the electric discharge-that is, the electric stab-and the drug-ah, the drug stab-will inevitably be'implicated in the innocent' in the process of catching the thief."

Jenny talked freely: “In contrast, one of the important breakthroughs of optogenetics technology is that it truly realizes that cells of the same kind can be precisely punctured: by installing switches on specific cells-specific ng promoters, microbial photosensitive proteins can It is very accurately expressed in a certain type of neurons, even if these neurons are intertwined with other nerve cells like a net, they can ensure accurate activation or inhibition under light."

"Before, Mr. Hayflick discovered that the repair protein has a strong aggressiveness. Paramecium can be transformed into a puppet-like existence by the repair protein. I think this optogenetic technology can also achieve this. ——They can control the boarder and turn it into a puppet. Kate, don’t you think this is a wonderful thing?"

"Is this... like this?"

Unconsciously, Catherine always felt shivering.

But... I always feel like it's amazing.

"Hmm, it's not just that!"

Jenny said: "Optigenes technology almost makes certain behaviors and light thorns happen synchronously. It does not need to wait for blood or other media to transport the thorn source to the target cell-in fact, the thorn arrives at the target cell at the speed of light; there is no half-life. Once the light is stopped, the thorns will end immediately after drug metabolism. Compared with the indirect thorns such as the regulation of gene transcription and expression through receptors, optogenetics technology makes the link between cause and effect more intuitive."

"Theoretically, optogenetics technology can be applied to any cell line-that is, cultured cells that can be continuously passaged for a long time-but the most popular one is its wide application in the field of neuroscience ~ lightnovelpub.net ~ it The huge technological breakthrough has allowed us to rethink and explore almost the entire neuroscience field from a new perspective-all neuroscience problems!" "Theoretically, optogenetics technology can be applied to any cell line-that is, it can Long-term continuous passage of cultured cells, but currently the most popular is its wide-ranging application in the field of neuroscience. Its huge technological breakthrough allows us to rethink and explore almost the entire neuroscience field from a new perspective— —All neuroscience problems!” “In theory, optogenetics technology can be applied to any cell line—that is, cultured cells that can be continuously passaged for a long time—but the most popular thing is its wide application in the field of neuroscience. Always feel that something strange is about to appear?

Catherine shivered.

I always feel as if this research will turn into something terrifying at the end...
