Chapter 66 Additive Construction

The human brain is divided into left and right hemispheres.The two hemispheres are connected by a "corpus callosum" composed of about [-] million nerve fibers.This bundle of nerve fibers 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 a person.

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

People without a corpus callosum are called "split brains."

In the 20s, Sperry, a professor of biology at the University of California, conducted a series of experiments on split-brain people.

If an image is placed on the left or right side of a split-brain person, 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-brain people who were willing to participate in the experiment sit in front of a wooden board.This board has a row of light bulbs arranged horizontally.These light bulbs will flash on his left and right sides respectively.

When the researchers asked the subjects to report what they saw, they all said 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 individually.But this time, they didn't respond.

The only plausible explanation seems to be that the right hemisphere of the brain, which is responsible for the left visual field, does not 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 flickered, although the subjects said "only the right side flickered", their hands accurately pointed out the light bulbs that flickered on the left, with a high accuracy rate , which is obviously statistically significant.

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

Subjects with split brains were unable to speak even when they saw a flashing light bulb on the left.

Because the right brain is not responsible for the language function.

In another experiment by Sperry, the subjects were asked to copy simple three-dimensional drawings (such as cubes) with their left and right hands respectively. Their left hands can basically complete the task, but their right hands can only draw a part. A pile of incomprehensible two-dimensional lines, without the slightest "three-dimensional sense".

That's because the left brain isn't responsible for "spatial imagery"—that's the job of the right brain.

Roger Sperry was awarded the Nobel Prize in Physiology or Medicine in 1981 for this experiment and a series of studies that followed.The congratulatory message presented by the Caltech school journal is: "Sperry, I would like to congratulate both the left and right hemispheres of your brain!"

Of course, the results of this study were later criticized by the academic circles.These criticisms mainly focus on the idea of ​​"unilateralization of left and right hemisphere functions of the brain" and the form in which this idea is expressed 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 incapable of understanding language, but the way it understands it is very different from the left hemisphere.And this right hemisphere's cognition 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 emphasis.

When a person reads a story, the left hemisphere of the brain is understanding written language.Extract meaning from the arrangement of words and sentences, and convert language symbols into 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 situation, and forming an overall impression of the style of the story.

This is the complete working process of the brain.

The same is true of cyber martial arts.

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

The internal strength and the language function are integrated with each other.

"So, for entry-level knights, the arrangement of the chips in the brain recommends the internal strength of the left hemisphere and the outer goal of the right hemisphere. But this does not mean that you only need half the brain to handle all confrontation games. Especially advanced Internal strength will definitely involve the functions of the whole brain. But I still recommend placing the internal strength chip on the left brain."

Xiang Shan said seriously.

Yuki looked at Xiang Shan, his body trembled, and he couldn't help laughing.

Xiang Shan sighed: "Did I not explain clearly enough?"

Yuki nodded: "It's very clear."

"So I rearranged the electronic part of the cranial cavity, is there a 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... I remembered that you used a kettle lid as a head cover before."

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

His wire was extracted from the remains of the prosthetic body of the little poisonous bug.

Yuki nodded quickly.

"Children can't be taught." Xiang Shan shook his head and walked towards the underground part.

Organization Z has bio-refining tanks and furnaces that can extract some metals and silicon by itself.However, these resources can only be converted 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 uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing 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 11D printer for the first time.

Compared with the subtractive manufacturing of the traditional industry, which "produces the rough shape first, and then cuts off the excess part with a knife", it saves more resources.

More important, though, is the flexibility of 3D printing technology.The production of parts by this technology is not like traditional industries, which require various corresponding molds, and one machine can produce countless kinds 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 upon hearing this: "This seems to be similar to 'martial arts'..."

"Yes. A digital model is a kind of 'information'. Except for the small power consumption of 'entry' and 'erasure', there is almost no other cost." Xiang Shan sighed: "Information should be the lowest cost in the information age Things. It's a pity that the rules specified by some strong people prevent this kind of information from being shared properly. The wealth and advantages they accumulated in the past era can be continued..."

Xiang Shan was a little lost in thought.If it wasn't for this extremely simple voice system that couldn't express his complex emotions, maybe Yuki would have heard the abnormality in 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 mentioned!" Yuki pointed forward excitedly.

Xiang Shan regained his senses and nodded.

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

Xiang Shan continued to do the same thing, testing the 3D printer.

Three robotic arms hang down from above the printer, and each of these three robotic arms has dozens of nanoscale nozzles connected with thin microtubes.These nozzles evenly eject nanoscale in mid-air.The magnetic field precisely confines the movement of the metal powder.Another mechanical arm at the top hangs down, and the mechanism with a radius of microns heats these parts.Then, another robotic arm sends out high-frequency mechanical waves, which cause a certain periodic motion to run through the metal's solidification process and control the alignment of the alloy crystals.

A small part is completed in an instant.

Xiang Shan's body shook slightly.

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

Become more familiar with the process.

Yes, familiar...

Various memorized parameters flowed out from the memory, and along with the internal force, were injected into this machine.Yuki was horrified to see that the electronic operation panel of this machine was refreshed crazily, almost becoming a messy pile of color blocks.

Soon, Xiang Shan's consciousness touched the extra data just now.

"A prosthetic skeleton with high versatility, the alloy parameters of the outer armor, thermal weapons... Tsk, this needs to be studied a little bit. I think the thermal weapons of this organization seem to show a better design idea than I remember. "Xiang Shan pressed his head: "Another adjustment is needed...Gliad's wireless signal transmitter, Paulus's and Leif's batteries must be installed..."

If it is really an option, then Xiang Shan would really like to replace it with the batteries of Gliad or "Green Steel Vulture" Daniel.Gliad is a heavy-duty vehicle prosthesis, while Daniel is simply a flying prosthesis, and the performance of its battery is far superior to those in Xiang Shan's hands.

It's a pity that Gliad's battery didn't have time to take it off at that time, and if he took it at that time, he couldn't shoot Tiehua at the welfare officer.Daniel's battery was directly blown up by the anti-aircraft gun.

"In addition, for the new spine, separate motor units must be installed on each segment. In the worst case, you need to consider the situation of using the spine to carry the head out of the prosthetic body."

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

"In addition, there are some parts needed for the 'Donkey' to upgrade..."
