I can extract side effects

"The CT scan of the brain showed that everything was normal, and there was basically no problem."

Jian Jianyun looked at Zhang Li's inspection report and showed a satisfied smile.

"The prognosis of the operation is also very good. As expected of a young man, he has strong resilience."

"Fortunately, Lao Chen didn't have an operation. He must not recover as fast as you. He is probably still dizzy now."

"Young people in their twenties are in the prime of life and in good health. Even if a stent is implanted in the brain blood vessels, the possibility of sequelae is not high, such as the most common cerebral thrombosis. The chance of getting this is extremely high, not to say no. Small, but it’s hard to say for a person in their forties.”

She rambled on a lot of precautions before stopping.

Chen Yiqing listened silently, with a smile on his face, nodded from time to time, and agreed: "Doctor Jian is right."

As for other people, naturally they will not express any opinions.

When Jian Lianyun finished speaking, he picked up the teacup on the table and poured water.

Chen Yiqing spoke in a timely manner: "The first human test was very successful and brought us a pleasant surprise."

"It turns out that the brain's ability to learn and adapt is much stronger than we imagined. I think Lily can handle things that require more skill."

"So, I think I can go straight to the big move."

"I understand. Are you going to make a bionic manipulator next?" Wang Dali asked excitedly, looking eager to fight.

Chen Yiqing didn't answer, but directly stretched out his right hand, clenched his five fingers into a fist, and then slowly stretched them out. After doing this several times, he looked at Wang Dali and asked back.

"How long do you think it will take to make a mechanical hand that can move fingers freely and make some fine movements flexibly?"

"This..." Wang Dali suddenly got stuck. He stretched out his hand silently, picked up a pen, and twirled it a few times between his five fingers to feel the strength and balance in it.

He said with some uncertainty: "Three months? Half a year? It depends on the specific needs, how detailed it is. If you pick up a pen to write, it will take a long time. It's much easier to just pick up a glass of water."

Chen Yiqing smiled slightly: "What about surfing the Internet? Operating mobile phones and computers to type, play games, even go shopping, order takeaway?"

Wang Dali breathed a sigh of relief, thought for a while, and frowned again: "It's a bit difficult, but it's not a big problem. Give me three months, and it should be done."

Chen Yiqing smiled and shook his head: "Dali, your thinking has gone astray. When it comes to computers, we should consider software solutions rather than pure hardware."

Wen Renlong listened on the sidelines, nodding repeatedly, approving.

"That's right, it's understandable that you hardware people can't change their minds for a while. If I do it, I don't need any manipulator at all. I can just convert brain signals into operations on the app. What about sending messages?" , write emails, order takeaway, so easy."

Wang Dali glared at him: "Then why don't you chop off your hands, and let the program handle all the eating, drinking, and messing with you? You don't even write a word, do you really think of yourself as a digital life?"

Seeing that the two were about to quarrel, Chen Yiqing hurriedly said: "It's not that I don't want to use the robot. This is currently relatively difficult. I can only do a few simple movements for the time being. It may take longer to make more delicate movements."

"That's why I thought that through some simple signal conversion, paralyzed patients can restore the ability to communicate with the outside world."

"If they use a brain-computer interface, they can operate computers and mobile phones, and surf the Internet proficiently. At least they will no longer feel lonely, and they can communicate better with family and friends, and they will be full of hope in life."

"They can even learn to play games, shop, chat, read books, and entertain themselves. In the information age, if a person can surf the Internet, his life will become full and full."

"A full-featured bionic manipulator, as you said, can't be completed within a year or so."

"Our project must produce certain results and let patients see hope before they can persevere in the experiment, otherwise they won't be able to wait that long, so using ideas to surf the Internet is a very good early-stage product that can meet certain needs of patients."

"Wait until the demand for Internet access is met, and then we will make manipulators to meet patients' needs for complex daily behaviors."

"What do you think?"

Wang Dali's eyes lit up instantly: "That's right, Chen Bo, you are absolutely right."

"If Zhu Jun can use the brain-computer interface to play games, he must be very happy."

"We do experiments for several months and half a year. How can patients have that patience? They must be disheartened when they see no results for a long time, and they don't want to come back."

"It's like a monkey experiment. You have to give them a little sweetness to keep cooperating."

"I understand, I understand, I understand too well."

He slapped his thigh, and instantly remembered the cake that his boss drew for him before. It was really big, round, fragrant and sweet. Apart from not satisfying his hunger, he could only smell it, so there was nothing wrong with it.

Once upon a time, he was like a monkey in the laboratory. As long as the boss gave him a few "pine nuts", he would be full of energy when working, as if he would never know what it means to be tired.

However, what humans are better than monkeys is that they have more desires and higher thresholds.

When "pine nuts" couldn't satisfy him, he began to learn to play tricks.

It wasn't until he came to Sanqing that the boss gave me enough bananas, which were delicious enough, which aroused his strong desire and worked tirelessly.

Wang Dali came back to his senses and asked the next question.

"Chen Bo, how will it be realized next?"

"Aren't we studying motor neurons? Isn't it a hand movement program? How to make it directly control the computer?"

Chen Yiqing smiled: "Actually, the principle is still the same. We human beings can't operate computers as deep as artificial intelligence, so we need to use the mouse, keyboard, and click on the screen to operate."

"It's the same with a brain-computer interface. We don't let the brain directly control the computer, but let the brain imagine that it uses both hands to control the computer through the keyboard and mouse, so that the relevant motor nerve signals can be converted into program instructions and transmitted to the computer. gone."

"The underlying logic of humans and computers is different. The brain is more advanced, the information processing is more three-dimensional, and the operation method is four-dimensional, because the movement of the human body not only has the movement of space, but also the continuation of time, which is an integration of time and space.

"Computers can only process two-dimensional plane information, and even complex video clips must be decomposed into pixels for operation."

"The two sides have no way to communicate directly at the moment, and can only manipulate through indirect means."

"Our research on the brain still has certain limitations. At present, we are still focusing on motor neurons, so we can only do this."

Wang Dali suddenly realized: "Wonderful, wonderful."

His thinking began to diverge: "Then, wouldn't it be possible to control the direction and movement of the wheelchair in the same way?"

Chen Yiqing nodded slightly: "Theoretically, it is indeed feasible. Let the patient imagine that he is using his hands to operate the wheelchair to move forward and turn, and then convert it into an electromechanical signal. After a certain amount of training, he can do it."

"Of course, it also depends on the mutual learning and adaptation between people, patients and machines, which is also very important."

"Achieving the goal of driving a wheelchair in a natural environment requires neuroplastic reorganization in the cerebral cortex."

"Some people's brains can quickly adapt to this change, and some people's brain activity patterns can't adapt to this change, and the effect is not much better."

Having said that, he looked at Zhang Li next to him, with a trace of tenderness on his face.

"People like Lily, whose brain learning and adaptability are top-notch, are very suitable as the initial learning template."

"With such an excellent program template, the difficulty for latecomers to learn is not so high."

Wang Dali instantly understood why Chen Yiqing chose Zhang Li as the first tester.

This good intention touched him greatly, and he couldn't help looking at Zhang Li.

I saw that her expression was very calm, her eyes implied expectation, and she did not show any irrational emotions at all.

Such a young scientist who is self-sacrificing, soft on the outside and strong on the inside, and emotionally stable, is indeed the best experimental subject.

For a moment, he understood the other party's behavior, maybe just like his own college entrance examination back then, for a certain life goal, no matter what he gave, he must achieve it.

As for Wen Renlong at the side, his gaze was always on Zhang Li. There was admiration, pity, and tenderness in his eyes. Complicated emotions were intertwined, and he was already fascinated by it.

*****

The next thing, everything is a matter of course.

Zhang Li sat in front of the screen again.

This time, what appeared in front of her was the usual computer interface, a keyboard and a mouse.

"It's much more difficult, but I believe you can do it, come on!"

Chen Yiqing and Wen Renlong cheered for her at the same time.

Zhang Li smiled faintly, made an ok gesture, and then faced the computer, skillfully operating it.

Kaka~

The mouse kept clicking, opening every icon on the desktop.

The browser is opened, and the webpage starts to scroll. After reading it, click X to close it.

Then came the email window, fingers twitching, typing non-stop, hitting send.

Finally, open Goudong’s page, search for products, keep jumping, carefully select each product, enter the address, and click to place an order.

When Zhang Li was doing these things, her brain signals were continuously collected and transmitted to the computer in the laboratory for in-depth analysis, trying to extract a motor program model for operating the computer.

A week later, the data collection is completed and the algorithm optimization stage is entered.

"How?" Chen Yiqing looked at Wen Renlong and asked with his eyes.

Wen Renlong nodded: "You can try."

His hair was messy, his chin was full of stubble of different shades, and his clothes also gave off a faint smell.

Chen Yiqing glanced at him gratefully, and said in a low voice, "It's done this time, I'll give you a long vacation and take a good rest for a few days."

Wen Renlong tapped the keyboard intently, without realizing it, and it took him a while to react, and he replied casually, "Yes."

"let's start!"

With an order, the brain-computer interface switch was turned on again.

The difference is that this time it is not the robotic arm next door, but the computer in front of it.

The keyboard and mouse were taken away.

Zhang Li drank the orange juice in the glass in one gulp and put it back to the original place.

The hands hang down naturally, and the whole person lies back on the chair loosely.

Start to deal with the computer in front of you wholeheartedly.

She stared intently at the mouse arrow on the screen.

Soon, the arrow started to move, clicking the icons on the desktop continuously, and one window after another popped up.

After a while, the WeChat chat window was opened.

The cursor is blinking.

Zhang Li pondered for a few seconds, then slowly typed out a line.

"Hello, world."

At the other end of the room, Wen Renlong suddenly jumped up from his chair and said in a trembling voice.

"She, she sent me a message."

Looking at the words "hello world" in the dialog box, Wen Renlong's nose was sour, and a line of tears flowed down uncontrollably.

He muttered to himself: "I understand. So, so, she also had this intention a long time ago."

Chen Yiqing and Wang Dali couldn't help but look at each other when they saw Wen Renlong's excitement.

Wang Dali whispered: "Aaron, what's the matter with you? Don't you just say hello? It makes you cry with excitement. Are all of you algorithmic people so sentimental?"

Chen Yiqing asked with concern: "Are you too tired? The work here is almost done. Do you want to take a rest?"

"You don't understand what this sentence means to programmers. She said this to me, I understand, I understand, we are really connected."

Wen Renlong waved his hands while wiping away his tears, the expression on his face fluctuated, surprise revealed touch, move mixed with infinite joy, and even a trace of inexplicable coyness.

At this moment, his heart was beating wildly, and he was filled with fear and joy at the same time.

"Ah, what should I do? She said such a sentence to me. How should I reply?"

A veteran in love for many years, at this moment, he is like a fledgling boy, at a loss, his mind is blank, and he only knows to giggle.

The two people next to him looked more and more wrong, exchanged glances again, decided not to speak, and just ignored him.

Chen Yiqing coughed lightly, with a happy expression on his face: "Very well, the function of mind surfing has been realized, and the project has been a great success."

"An incomparably great and romantic technological miracle will be shown to the world in our hands."

"I think this is also the real meaning of what Lily said to us."

"By the way, Aaron, since Lily said hello, you should give her one too."

These words pulled Wen Renlong back from his infinite reverie.

"good!"

He responded immediately, then thought for a while, and happily typed a paragraph.

while (i. findYou()){

if (i. get()==you {

System.out.print("Hello, World!");

}

}

Mouse click, send.

Watching this scene.

Chen Yiqing: "???"

Wang Dali: "???"

The two looked at each other with black lines all over their heads, and at the same time showed the expressions of "I'm afraid this is not a fool".

The veins on Chen Yiqing's forehead were throbbing, but he took a look at the two big bags under Wen Renlong's eyes, and immediately swallowed back his words.

"What is Aaron doing now? Forget it. Anyway, the project has been successful, so don't worry about him."

Chen Yiqing comforted himself, turned around and walked away, he was afraid that if he continued to watch, he would not be able to help himself, and drove Wen Renlong out.

But Wen Renlong didn't notice everything around him, and he focused all his attention on the dialog box in front of him.

He was feeling uneasy at the moment, enduring suffering and anxiously waiting for the other party's reply.

Just a few seconds, to him, seemed as long as a century.

Finally, the other party replied.

Zhang Li: "???"

Three big question marks appeared in the dialog box.

Wen Renlong was stunned in front of the computer as if he had been hit by a sap.

It took him a while to react, his brows were tightly furrowed, and he tried hard to think about the meaning.

"What's the meaning?"

"Could it be that my post was too profound and she didn't understand it?"

"Impossible, she is so smart, how could she not understand."

"It's not impossible, she has never learned programming."

"Then, why don't you change it to something simpler?"

"Forget it, girl, she must be shy, if she understands it, she should not understand it."

He scratched his head and ears, restless, and his mood was like riding a roller coaster, drifting to the clouds for a while, and falling into the mundane world for a while.

At this time, my thoughts are flying, turning back and forth.

Suddenly, there were two beeps.

Zhang Li sent another message, this time it was very simple, just a smiling face.

However, Wen Renlong smiled instantly as if seeing the most beautiful words in the world.

All the haze in my heart disappeared in an instant like a sunny day after rain.

All that was left was a maniacal laugh.

"Hahaha, I knew it, she must have understood it."
