Chapter 610

There are two main reasons why it is necessary to wait until Lu Xuanyu becomes a mature benchmark before conducting the prosthetic test.

One is the acquisition of neural signals.

Over time, some proteins will accumulate inside neurons, and with the metabolism of the cell membrane, some metal-based proteins will be embedded into the cell membrane composed of phospholipids.

These gradually alter the action potential properties of neurons.

Of course, all this is imperceptible.

According to the existing records, newborn benchmarks only feel that as time goes by, their nerve reflexes will become faster and faster, and their brains will turn faster and faster.

There will be a certain improvement in the performance of the human brain.

This change occurs only at the cellular level and hardly alters the structure of the neuronal network.Therefore, it will not have too much influence on one's self-awareness.

At least at this stage, there is no evidence that it has a significant impact on personality.

To use an inappropriate metaphor, it's like "speeding up" your own brain.

And there's a huge benefit here—the electrical signal will become stronger and easier to be recorded by the instrument.

In addition, since metal-based organisms can use electric field energy to maintain life responses, the problem of "electrode stimulation leading to nerve tissue inflammation" can also be basically avoided.

The difficulty of brain-computer interface signal input just disappeared.

The other one is to "reduce the body's rejection reaction to the prosthesis".

Humans develop an immune response to most things that are "not self".This is a matter of course.

No matter what foreign object enters the body, it triggers an immune system response—not just germs or viruses, but larger foreign objects as well.

"Prosthetic body" is of course also included.

This mechanism is likely to be used in response to larger foreign bodies such as parasites.Without this mechanism, human beings may not be able to evolve smoothly to today.

But today, this rejection of prosthetics has become a difficulty that must be faced on the road to prosthetics.

This difficulty is also divided into multiple aspects.

For example, mechanical damage. "Inflammatory response", that is, the local fever, redness and swelling that occurs after the body is injured, is often beneficial to the human body.It controls the reproduction of pathogens and allows immune cells to arrive quickly.But it's not just pathogen infection that can lead to an inflammatory response, any damage to cells can lead to an inflammatory response.

Including cases of "sprained foot" or "muscle strain" that are not infected at all.

However, the prosthetic body and the physical body are not integrated, and it is difficult to "seamlessly connect".When in motion, they create friction or stress, sustained mechanical damage, and a persistent inflammatory response.Frantic immune cells attack all tissues at the junction.

On the other hand, macrophages will also actively wrap those foreign bodies.

Traditional invasive implants can easily lose their original function due to such reasons.

"—Of course, these problems will be solved or alleviated with the changes in your body." Florence said: "This is the convenience of the benchmark."

Lu Xuanyu's wife covered her chest: "I still think it's weird. It's so dangerous...the prosthetic body..."

At this moment, Lu Xuanyu is used to "scientists' way of speaking". He nodded and said, "They just like to talk like this, just get used to it."

Florence continued: "In fact, traditional implants can already avoid this kind of thing to a certain extent. For example, biocompatible materials."

"The human body—here specifically refers to the body of Homo sapiens—has a good affinity for titanium alloys. As the encapsulation of femoral head, skull repair material or implantable radioactive source particles, it is not easy to cause inflammation. But titanium The performance of the alloy is doomed that it cannot directly construct complex systems in the body."

"However, the benchmark man who is a metal-based organism is different. The biological affinity of most metals to benchmark humans has reached the level of titanium alloys to Homo sapiens. Lead, cadmium, chromium, nickel, antimony , the affinity of metals such as tungsten is even higher. Engineers can directly use your cells and electronic components to build machinery in your body-of course, Mr. Voigt also has a project to study the adjustment of the human body's affinity for different metals. peaceful way."

"In addition, traditional prosthetics need a large area of ​​contact with the human body, and it is difficult to completely avoid mechanical damage to the body at the joint during exercise. Therefore, existing prosthetics are generally nested and non-implantable. Implantable , can only be directly nailed to the bone. But IMHO, the human skeleton did not need to take on such additional tasks during the evolutionary stage, so it does not perform very well in the face of such tasks.”

"However, the prosthetic body designed by our company is not the same..."

Florence clicked the button in his hand, and the content on the screen changed, showing several white parts with irregular shapes.

"Culture and induce my own osteoblasts in vitro, and then 3D print them into implants that fit the human body. This 'artificial skeleton' is loose and porous, with signal factors attached in the gaps, which can induce the human body to form dense connective tissue—inside There are even signaling molecules that induce angiogenesis. And it would be a 'platform'."

On the screen, that part was reversed.Under the bony shell is a full mechanical structure.

"There will be metal wires that are friendly to the human body and go out from here to connect with your central nervous system."

"In addition, metal-based organisms can maintain cell activity with electric fields, so small currents will not trigger inflammation in the nervous system. Input and output systems will be integrated on the surface of your brain-but not much at this stage."

"The above is the whole content of this briefing session. Do you have any questions you don't understand?"

Lu Xuanyu's wife raised her hand and said, "This...that...if the 'input problem' is solved...then if some bad person sends something...bad things to the chip implanted in his brain...that... "

"Your concerns are meaningful, but please don't worry." Florence smiled and said, "First of all, at this stage, we will not install a network card on the brain implant - it cannot directly receive wireless signals from the outside world. The signal of the prosthesis system itself will be processed through a wired connection. Our boss personally grasped the safety barrier between the prosthesis and the brain implant. This security system is open to the supervision departments of various countries. Although the For security reasons, the relevant departments of those countries will not release the source code to the public, but you can consult any country you think is credible.”

"In addition, numerous 'white hats' were involved in testing this security system."

"If you are not at ease with us, you can also use a system developed by a third party. As long as the principle of 'opening up to regulatory agencies for inspection' is followed, we do not exclude third-party development."
