The human brain is divided into left and right hemispheres. The two hemispheres are connected through the corpus callosum, which is composed of approximately 200 million nerve fibers. This nerve fiber bundle is located in the 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 a person's corpus callosum.

Of course, it would be too inhumane to remove someone's corpus callosum for the sake of research. But there are indeed people in the world who really have no corpus callosum at all. A large group of these people suffered from epilepsy that could not be controlled by the medical science at that time, and had to be treated by cutting off the corpus callosum.

Such people without a corpus callosum are called "split brains."

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

If an image is placed on the left or right side of a split-brained person, the visual signal will first be transmitted to the corresponding side of the brain hemisphere. Sperry's original testing project was to have split-brained people who were willing to participate in the experiment sit in front of a wooden board. This wooden board has a row of light bulbs arranged horizontally. The bulbs will flash on his left and right sides.

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

The researchers then asked the light bulb on the left side of the subject's field of vision to flash alone. But this time, they had no reaction.

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 flashing light bulbs, although the subjects said "only the right side has flashing", their hands accurately pointed out the flashing light bulbs on the left with high accuracy. , obviously statistically significant.

In other words, the right hemisphere can actually see and process visual signals. However, this visual signal cannot enter the language function and be transformed into expressive sentences.

Subjects with split-brain were unable to tell even if they saw the flashing lightbulb on the left.

Because the right brain is not responsible for language function.

Another experiment conducted by Sperry asked subjects to copy simple three-dimensional drawings (such as cubes) with their left and right hands respectively. Their left hand could basically complete the task, but their right hand could only draw one. There are a lot of incomprehensible two-dimensional lines, but there is no sense of "three-dimensionality" at all.

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 or Medicine for this experiment and a series of subsequent studies. The Caltech magazine’s congratulatory message for him was: “Sperry, I would like to congratulate both hemispheres of your brain!”

Of course, this research result was later criticized by the academic community. These criticisms mainly focus on the idea of ​​"lateralization of the function 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, there is evidence from Sperry's own experiments that the human right hemisphere is not completely unable to understand language, but the way it understands is hugely different from the left hemisphere. And this right hemisphere's understanding of language may also be an important part of ordinary people's language cognition.

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

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

This is the complete working process of the brain.

The same is true for cyber martial arts.

What external skills require is the intuitive imagination of geometric problems and the arrangement of tactics.

Internal strength and language function are integrated with each other.

"So, for beginners, the layout of the chip in the brain is recommended to be the left hemisphere for internal skills and the right hemisphere for external skills. But this does not mean that you only need half a brain to handle all confrontational games. Especially for advanced players Internal strength will definitely involve the functions of the whole brain. But I still recommend placing the internal strength chip in the left brain."

Xiangshan said seriously.

Youki looked at Xiang Shan, his body trembling and he couldn't help but want to laugh.

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

Yuki nodded: "It's clear."

"So I rearranged the electronic part inside the skull. Is there any problem?"

Yuki shook his head.

"Then why are you laughing?"

"I'm sorry, Master..." Yuki twitched: "The way you tied the skull with a wire... reminds me of you using a kettle lid as a head cover before."

Xiang Shan was furious: "What's wrong with the kettle lid? And this is just a temporary measure! I'm going to get a better skull now, you know?"

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

Yuki nodded quickly.

"A child cannot be taught." Xiang Shan shook his head and walked towards the underground part.

Organization Z has biorefinery tanks and furnaces that can extract some metals and silicon by themselves. However, these resources must be converted into usable resources through specific processing.

The props used for this kind of processing are 3D printing technology.

3D printing, also known as additive manufacturing, is a technology that uses bondable materials such as powdered metal or plastic to construct objects by printing layer by layer based on digital model files. 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 with a 3D printer for the first time.

Compared with traditional industry, subtractive manufacturing which "first produces a rough shape and then uses a tool to cut off the excess" is more resource-saving.

More important, however, is the flexibility of 3D printing technology. The production of parts using this technology is different from traditional industry, which requires various corresponding molds. One machine can produce countless types of parts.

Compared with physical molds, "digital models" can be said to be almost "costless".

As long as you are willing to share.

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

"Yes. Digital models are a kind of 'information'. Except for the small amount of electricity consumed by 'entering' and 'erasing', there is almost no other cost." Xiang Shan sighed: "Information should be the lowest cost in the information age. It's a pity that the rules specified by some powerful people prevent this kind of information from being shared properly. The wealth and advantages they accumulated in the past era can be continued..."

Xiangshan was a little lost in thought. If it weren't for the fact that this extremely simple voice system couldn't express his current complex emotions, maybe Yuki would have heard the abnormality in his tone at this moment.

Xiangshan always felt that when talking about this topic, he seemed to be abnormal... abnormal...

"Master, that's the 3D printer you're talking about!" Yuki pointed forward excitedly.

Xiang Shan came back to his senses and nodded.

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

Xiangshan still followed the same method and tested this 3D printer.

Three robotic arms hang down from above the printer. Each of these three robotic arms has dozens of nanoscale nozzles connected to fine microtubes. These nozzles spray nanometer-sized particles evenly in mid-air. The magnetic field precisely constrains the movement of the metal powder. Another robotic arm hangs down from the top, and a mechanism with a micron radius heats these components. Then, another robotic arm emits high-frequency mechanical waves to cause a certain periodic motion throughout the solidification process of the metal and control the arrangement of the alloy crystals.

A small part is completed in an instant.

Xiangshan trembled slightly.

I don't know why, but he seems more...more...

Become more familiar with the process.

Yes, familiar...

Various memorized parameters flowed out of the memory and were injected into the machine along with the internal force. Youki was horrified to see that the machine's electronic operation panel was refreshing like crazy, almost turning into a bunch of messy color blocks.

Soon, Xiangshan's consciousness came into contact with the newly acquired data.

"A highly versatile prosthetic skeleton, the alloy parameters of the outer armor, and thermal weapons... Tsk, I need to do a little research on this. I think this organization's thermal weapons seem to show a better design idea than the one I remember. "Xiang Shan held his head: "In addition, some adjustments are needed...Gliad's wireless signal transmitter, Paulus and Leif's batteries must be installed..."

If he really had the choice, Xiangshan would really like to replace it with Griliad or "Blue Steel Vulture" Daniel's battery. Gliad is a heavy-duty vehicle prosthetic, while Daniel is simply a flying prosthetic, and its battery performance far exceeds those in Mukoyama's hands.

It's a pity that Griad's battery didn't have time to detach it at that time, and if it was taken at that time, it wouldn't be able to fire iron beams at the welfare officer. Daniel's battery was directly blown up by an anti-aircraft cannon.

"In addition, each section of the new spine must be equipped with a separate motion unit. In the worst case, we need to consider the situation of using the spine to carry the head away from the prosthesis."

"By the way, there is also a protective skull..."

"There are also some parts needed for upgrading the Donkey..."
