The human brain is divided into a left hemisphere and a right hemisphere. The two hemispheres are connected by a "corpus callosum" composed of about 200 million nerve fibers. This nerve fiber bundle is located in the very center of the brain and has an arcuate cross section.

If the corpus callosum is removed, the connection between the two hemispheres of the brain will be severed. In other words, if you want to study the function of a single hemisphere, you only need to remove the corpus callosum of one person.

Of course, removing someone’s corpus callosum for research is too inhuman. But there are people in the world who really don't have a corpus callosum at all. Among these people, there is a large group, because they suffered from epilepsy that was not controlled by medicine at the time, and had to be treated by cutting the corpus callosum.

This type of person without a corpus callosum is called "split brain."

In the 1960s, Sperry, a professor in the Department of Biology at the University of California, conducted a series of experiments on split-brain people.

If a certain image is placed on the left or right side of a split-brain person, then this visual signal will first be transmitted to the corresponding side of the brain hemisphere. And Sperry's initial testing project was to allow split-brain people willing to participate in the experiment to sit in front of a wooden board. There is a row of light bulbs arranged horizontally on this board. These bulbs will flash on his left and right sides respectively.

When the researchers asked the subjects to report what they saw, they all said that they only saw the light bulb on the right flickering.

Then the researchers let the light bulb on the left side of the subject’s field of vision flash alone. And this time, they did not respond.

The only reasonable explanation seems to be that the right hemisphere of the brain, which is responsible for the left visual field, cannot process this visual signal and is a "blind spot."

But subsequent experiments overturned this explanation. When the researchers asked the subjects to identify all the light bulbs that flashed, even though the subjects said "Only the right side has flashes", their hands accurately pointed out the light bulbs that flashed on the left side with high accuracy. , Is obviously statistically significant.

In other words, the right hemisphere can actually see and process visual signals. But this visual signal cannot enter the language function and be transformed into a statement that can be expressed.

Subjects with split brain, even if they saw the light bulb flashing on the left, they could not tell.

Because the right brain is not responsible for language functions.

In another experiment by Sperry, subjects were asked to copy simple three-dimensional pictures (such as cubes) with their left and right hands. Their left hand can basically complete the task. , But the right hand can only draw a bunch of incomprehensible two-dimensional lines, without the slightest "three-dimensional feeling".

This is because the left brain is not responsible for "spatial imagination"-that is the job of the right brain.

Roger Sperry won the 1981 Nobel Prize in Physiology and Medicine for this experiment and a series of subsequent studies. The congratulatory message from the California Institute of Technology Academy journal was: "Sperry, congratulations to the left and right hemispheres of your brain!"

Of course, this research result was later received by the academic community. criticize. These criticisms mainly focused on the idea of ​​"unilateralization of the functions of the left and right hemispheres of the brain" and the form of expression of this idea to the public and the media.

In fact, in Sperry’s own experiments, there is evidence that the right hemisphere of humans is not completely incomprehensible, but the way it understands it is vastly different from that of the left hemisphere. And this right hemisphere's cognition of language may also be an important part of ordinary person's linguistic cognition.

Normal people do not only have one brain, nor do they have two brains. The left and right hemispheres just have their own emphasis.

When a person reads a story, the left hemisphere of his brain is understanding written language. Extract meaning from the arrangement of words and sentences, and convert language symbols into speech, so that it can be understood in consciousness. The right hemisphere is responsible for understanding the emotional expression of the story, imagining its specific visual situation, and forming the overall impression of the story style.

This is the complete operation of the brain.

The same is true for cyber martial arts.

What external power needs is the intuitive imagination of geometric problems and the arrangement of tactics.

The internal strength is integrated with language functions.

"So, for beginners, the placement of the brain chip is recommended for the left hemisphere internal strength and the right hemisphere outer sect. But this does not mean that you only need half of your brain to handle everything. It’s a game of confrontation. Especially the profound internal strength will definitely involve the function of the whole brain. But I still recommend placing the internal strength chip on the left brain."

Xiang Shan said in deadly earnest.

Yuki looked at Xiang Shan, shaking her body and couldn't help but want to laugh.

Xiang Shan sighed: "Didn’t I explain clearly enough just now?"

Yuki nodded: "Very clear."

"So I rearranged the intracranial cavity Is there a problem with the electronics part?"

Yuki shook his head.

"Then what are you laughing at?"

"Sorry Master..." Yuki twitched: "The way you tie your skull with a wire...I remember you before Use a kettle lid as the head cover."

Xiang Shan was furious: "What is the problem with the kettle lid? And this is just a stopgap measure! I have to get a better skull now, don’t you? "

His wire was pulled out from the remains of the prosthetic body of the little poison insect.

Yuki quickly nodded.

"Children are not to be taught." Xiang Shan shook his head and walked towards the underground part.

Z organization has biorefinery tanks and furnaces that can extract some metals and silicon by itself. But these resources must be transformed into usable resources through specific processing.

This kind of processing props is 3D printing technology.

3D printing, also known as additive manufacturing, is a technology that builds objects based on digital model files and uses adhesive materials such as powder-like metal or plastic to print layer by layer. Simply put, as long as the corresponding materials and digital models are prepared, it can quickly produce props of any shape.

The "material" here can even be living biological cells. In November 2012, Scottish scientists used human cells to print artificial liver tissue using a 3D printer for the first time.

Compared with the traditional industry, "Mr. produces a rough shape, and then uses a tool to cut more than part" subtractive manufacturing, which saves more resources.

However, what is more important is the flexibility of 3D printing technology. This kind of technology produces parts, unlike the traditional industry, it requires a variety of corresponding molds, and one machine can produce countless kinds of parts.

Compared with the physical mold, the "digital model" can be said to be a kind of almost "no cost".

As long as you are willing to share.

Yuki heard this, nodded: "This seems to be similar to'martial arts'..."

"Yes. Digital models are just a kind of'information'. Except Apart from the small amount of electricity consumed by'enter' and'erase', there is almost no other cost." Xiang Shan sighed: "Information should be the lowest cost thing in the information age. It is a pity that certain rules specified by Powerhouse, This information cannot be shared well. The wealth and advantages they have accumulated in the past era can be continued..."

Xiang Shan was a little surprised. If it weren't for this extremely simple voice system that couldn't express his current complex emotions, perhaps Yuki would have heard the abnormal tone of his tone at the moment.

Xiang Shan always feels that when talking about this topic, he seems to be abnormal...abnormal...

"Master, that is the 3D printer you are talking about!" Yuki pointed forward excitedly.

Xiang Shan came back to his senses, nodded.

In front of the master and disciple, there are three 3D printers of different specifications. One is larger and higher-end, and two are smaller.

Xiang Shan still did the same, testing this 3D printer.

Three robotic arms hang down from the printer. Each of these three robotic arms has dozens of nanometer nozzles connected to thin Microsoft tubes. These nozzles spray nanometers evenly in the air. The magnetic field precisely constrains the movement of the metal powder. Another robotic arm at the top hangs down, and a mechanism with a micrometer radius heats these parts. Subsequently, another mechanical arm sends out a high-frequency mechanical wave, which causes a certain periodic motion through the condensation process of the metal to control the arrangement of the alloy crystals.

A small part is completed in an instant.

Xiang Shan's body shook slightly.

I don't know why, he seems to be more...more...

more familiar with this process.

Yes, I am familiar with...

The parameters memorized all the time flowed out of memory, and were injected into this machine with Inner Strength. Yuki was horrified to see that the electronic operation panel of this machine was refreshed frantically, almost becoming a mess of color blocks.

Soon, Xiang Shan's consciousness touched on the newly added data.

"A highly versatile prosthetic skeleton, alloy parameters of the outer armor, thermal weapons...Hey, this has to be studied a bit. I think the thermal weapons of this organization seem to behave better than I remember This is a better design idea." Xiang Shan held his head and said: "In addition, we need to adjust...Gliard's wireless signal transmitter, Paulus and Leif's batteries must be installed..."

If you can really choose, then Xiang Shan would really like to change to Gliard or "Qinggang Vulture" Daniel's battery. Gliard is a heavy vehicle prosthesis, and Daniel is simply a flying prosthesis. The performance of its battery is far superior to that of Xiang Shan.

Unfortunately, Gliard's battery had no time to buckle it, and if it was taken at that time, it would be impossible to fire iron flowers at the welfare officer. And Daniel's battery was directly exploded by the anti-aircraft cannon.

"In addition, for that new spine, a separate motion unit must be installed on each segment. In the worst case, you need to consider the situation of using the spine to take the head away from the prosthesis."

"There are also some parts needed for the upgrade of the donkey..."
