The human brain is divided into the left hemisphere and the right hemisphere. The two hemispheres are connected through a "corpus callosum" composed of about 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 the corpus callosum of a person.
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. Among these people, there is a large category because they suffer from diseases that cannot be controlled by medicine at the time.
Epilepsy can only 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 a certain image is placed on the left or right side of a split-brained person, then the visual signal will first be transmitted to the corresponding side of the brain hemisphere. And Sperry's original test project was to let split-brained people who were willing to participate in the experiment
A person sits in front of a wooden board. There is a row of light bulbs arranged horizontally on the board. These light bulbs will flash on his left and right sides.
And when the researchers asked the subjects to report what they saw, they all said they only saw the light bulb on the right flashing.
Then, the researchers asked the light bulb on the left side of the subjects' 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 responsible for the left visual field cannot process this visual signal and is a "blind spot."
But the following 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 bulb on the left has a very high accuracy and is 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 converted into expressive sentences.
Subjects with split-brain were unable to tell even if they saw the flashing lightbulb on the left side.
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 bunch 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 and Medicine for this experiment and a series of subsequent studies. The congratulatory message presented to him by the Caltech journal was: "Sperry, to Your Excellency
Congratulations from both hemispheres of the brain!"
Of course, this research result was later criticized by academic circles. These criticisms mainly focused on the idea of "lateralization of left and right hemisphere functions 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,
Perhaps it is also 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 emphasis.
When a person reads a story, the left hemisphere of the brain is understanding the written language, extracting meaning from the arrangement of words and sentences, and converting the linguistic symbols into speech 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 internal power in the left hemisphere and external power in the right hemisphere. 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."
Xiang Shan said seriously.
Yuki looked at Xiang Shan, his body trembling and he couldn't help but want to laugh.
Xiang Shan sighed: "Didn't I explain it clearly enough just now?"
Yuki nodded: "It's very clear."
"So I rearranged the electronic parts in 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." He shook his head towards the mountain and walked towards the underground part.
Organization z has biorefinery tanks and furnaces that can refine some metals and silicon. 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 adhesive 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 you are ready
With the corresponding materials and digital models ready, it can quickly produce props of any shape.

.
Compared with traditional industry, subtractive manufacturing that "first produces a rough shape and then uses a tool to cut off the excess parts" is more resource-saving.
However, what is more important is the flexibility of 3D printing technology. This technology produces parts, unlike traditional industries, which require 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'. Apart from 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 in a daze. If it weren't for the fact that this extremely simple speech system couldn't express his current complex emotions, Yuki might have heard the abnormality in his tone at this moment.
Xiang Shan always felt that when talking about this topic, he seemed 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 and nodded.
In front of the two masters and apprentices, there are three 3D printers of different specifications. One is larger and higher-end, and the two are smaller.
Xiangshan still followed the same method and tested this 3D printer.
Three robotic arms hang down from the top of the printer. Each of these three robotic arms has dozens of nano-scale nozzles connected to fine microtubes. These nozzles spray out nano-scale evenly in mid-air. The magnetic field is precisely constrained.
The movement of metal powder. Another mechanical arm at the top hangs down, and a mechanism with a radius of microns heats these components. Then, the other mechanical arm emits high-frequency mechanical waves, causing some periodic movement throughout the solidification process of the metal to control the arrangement of the alloy crystals.
.
A small part is completed in an instant.
Xiangshan trembled slightly.
I don't know why, he seems to be 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. Yuki saw in horror that the electronic operation panel of the machine was refreshed crazily, almost turning into a mess of colors.
piece.
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 and said, "In addition, some adjustments need to be made...Gliad's wireless signal transmitter and Paulus and Leif's batteries must be installed..."
If he could really choose, Xiangshan would really like to replace it with the battery of Griad or "Blue Steel Vulture" Daniel. Griad is a heavy-duty vehicle prosthetic, and Daniel is simply a flying prosthetic, and its battery
The performance far exceeds those in Xiangshan's hands.
It's a pity that Gliard's battery didn't have time to detach it at that time, and if it was taken at that time, it would not be able to fire Tiehua at the welfare officer. Daniel's battery was directly exploded by the 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..."
