The experiment officially started.
Zhang Li sat on a chair, put on her headphones, and focused on playing the game.
The neural electrical signals in her brain are clearly transmitted to the computer through a special multi-channel amplifier.
Each action potential lasts 1 millimeter, and the fluctuations are displayed on the computer screen, showing the brain's real-time activity.
The rapidly flashing matrix diagrams attracted everyone's attention.
When these electrical signals unfolded in front of everyone, they followed them eagerly, trying to decipher the mysteries and find the precise processing process of the brain.
Zizzi~
Zizzi~
A loud FM radio sound suddenly sounded in the room.
This is the sound of neurons firing. It slithers through the computer, slowly flows out of the speakers, and spreads wantonly in the air.
Beautiful and moving, like a serenade,
At this moment, the brain is like the greatest musician, firing on all cylinders, creating a symphony of neurons.
Each neuron creates small sparks of action potentials, like drummers, fiddlers, trumpeters, and flute players, dancing their hands and playing notes of thought.
Different clusters of neurons form a band, playing a high-pitched symphony of life under the diligent command of the commander of the brain.
The massive electrical activity generated by these clusters of dozens of neurons forms an unstoppable flow of electrical pulses, like a brewing ocean of electrons.
In a piece like this, every single individual has no meaning.
But when they come together, it makes sense.
Together they define a huge brainstorm and record the epic of everyone's life.
Every electrical signal jumps in time and space, becoming a beautiful note that defines each person, making him a wonderful existence that is both unique and similar.
Every action, every feeling, every dream, every memory, every sadness, and every joy is recorded one by one, shaping the person into a unique individual.
When this life cycle of thinking flow was first born, it was an unpredictable seed.
As time passed, it quickly grew into twisted waves, all the way to the place where the pain disappeared - the mysterious and inscrutable mantle of the cerebral cortex.
This neuronal aria is charming and endlessly varied, allowing people to reach the unknown realm of the brain while listening.
"It's the brain singing."
"She was happy, I could hear it."
Chen Yiqing murmured to himself, staring at the neuron electrical signals on the screen as if he had lost his mind.
Years of painstaking research are deeply intertwined with the hope that tens of thousands of paralyzed patients can stand up.
It constantly drives him, eager to enter this unknown territory and conduct a new round of exploration.
"It sounds like a thunderstorm in the sky on a gentle summer night, crazy and beautiful at the same time."
"It makes people addicted, but also deeply in awe, as if one accidentally encountered the miracle created by nature."
Jian Jianyun was filled with emotions. Her eyes never left the screen. Although she couldn't understand clearly, the matrix that changed rhythmically with the sound still opened her eyes.
She had observed real stained and sliced brain cells under a microscope, and had seen the bloody cerebral cortex of patients up close, but this was the first time she heard the music the brain sang when thinking, and saw the notes composed by neurons.
At this time, she was like the most devout believer, stepping into the palace of neurology, undergoing the sacred baptism both visually and auditorily.
More pious, and more hopelessly in love with this fragment of thought.
"This is her sharing her most precious possession, her mind."
"She allowed us to explore her brain and dedicated herself to the benefit of millions of people in the future. This is the greatest example of altruism. Although she is a woman, she is also a role model for our generation."
Wen Renlong's voice was very low, with a faint tremor. It was unclear for a moment whether he was talking to himself or to everyone.
However, Wang Dali, who was next to him, obviously heard it, so he immediately agreed: "Yes, we must not let down her dedication, and we must start working immediately."
Chen Yiqing reacted quickly and issued work instructions quickly.
"Next, let's repeat the same steps we did on the monkey."
"Extract and record the activity of as many neurons as possible, and then run these electrical signals on a series of simple mathematical models to extract the motor commands Lily needs to move her arms and hands. For example, the wrists, elbows and shoulders are constantly moving The changing spatial position and speed, and the strength of her grip on the joystick.”
"These instructions can also be derived from linear combinations of Lily's neuron activity, and the calculations are very simple."
"Let's get started, step by step."
Thirty minutes after the experiment started, Zhang Li's movements became more and more accurate, her performance became better and better, and her game playing level improved.
At the same time, mathematical models are constantly improving until they are perfected.
When the model became stable, Wang Dali sent these digital signals to the robotic arm next door.
The robotic arm appeared on the monitor, and everyone stared at the screen without blinking, for fear of missing its activation.
At first, the robotic arm hesitated for a few seconds, as if it could sense that this momentous moment was coming.
Soon, the robotic arm finally moved, simulating the movements of Zhang Li's arms, palms, and fingers.
Now, her mind not only directly controls her own arm, but also controls the robotic arm in the next room.
The robotic arm followed her brain's instructions and moved with ease, just like her own arm.
There is not much difference between the two. The robotic arm can even move faster in realizing the instructions of the brain.
Gradually, the movements of the robotic arm became more and more accurate.
This shows how powerful the motor instructions transmitted by the brain are.
"It's time." Chen Yiqing said nervously, then stood up, walked over and moved the joystick in Zhang Li's hand out of her reach.
After he left, the game screen was still playing on the display.
Wenrenlong very quickly switched the control body of the game from a joystick to a wrist of a robotic arm.
The robotic arm receives instructions from the brain-computer interface.
This means that from now on, if Zhang Li wants to continue playing, win the game, and then get the rewarded juice, she has only one choice.
Operate a brain-computer interface to do it all.
No matter how complex the task is.
In other words, Zhang Li must rely on her brain's imagination to control the robotic arm.
She had to imagine the robotic arm as her own, manipulating equipment in another room to complete the game on the screen in front of her.
This was her first time. She had not been trained in this area before and had to imagine how to operate the brain-computer interface.
A historic moment has arrived.
Everyone held their breath, waiting for a miracle to happen.
Zhang Li stared at the computer screen, stretched out her arms, and made movements like playing games.
Everyone turned their heads and looked at the monitor, only to see that the robotic arm was motionless.
So, they all sighed again.
Zhang Li tried a few more times, and the robotic arm moved, but it did not make any formal movements, let alone play games.
The expression on her face became a little complicated, confusion and surprise intertwined.
After some hesitation, she tried several more times without success.
Zhang Li said nothing and fell into deep thought.
Wen Renlong was a little anxious. He stood up suddenly and was about to say something.
Chen Yiqing grabbed him and whispered.
"Don't disturb her. She can only rely on herself in this matter. We are all inexperienced, so it would be inappropriate to give random opinions and might disturb her thoughts."
Wen Renlong sighed slightly and sat back.
The others didn't dare to say anything, and just looked at her silently, waiting eagerly.
About five minutes later, Zhang Li suddenly raised her hands, snapped her fingers with her left hand, and made an OK gesture with her right hand.
She seemed to be telling everyone that she knew what to do.
Everyone suddenly became energetic.
Immediately afterwards, Zhang Li lowered her hands naturally and relaxed.
She stared at the screen, focused on the game, waiting for the gopher to show up and hit the thunder stick.
When the idea just arises, before the mechanical arm moves.
Almost instantly, the sound and flashes of hundreds of action potentials filled the room.
At the same time, the brain-computer interface immediately transmitted the movement instructions extracted from her brain to the robotic arm.
As the gopher's head emerged from the hole, the robotic arm on the monitor began to move.
It was like searching for a ghost, searching for an invisible and intangible target in the empty room of the control room.
The locations of these targets only exist in Zhang Li's eyes and brain.
The robotic arm is in action, and on the screen in front of Zhang Li.
The big stick fell from the sky, drew a beautiful arc, and hit the gopher's head perfectly.
This is the first goal of the robotic arm.
Done with great precision.
After that, it continued to strike, hitting the gopher repeatedly.
Just like humans, they play the game with great interest.
These beautiful movements come entirely from Zhang Li's brain activity.
Now, Zhang Li can play video games using only her thoughts.
No more need to use your own arms.
Her brain was completely liberated from the limitations of the biological body.
The brain's activity signals got rid of the constraints of the body, passed through the walls of the laboratory, carried her every spontaneous will, and came to another room, driving the robotic arm to complete its mission.
Seeing the scene in front of him, Chen Yiqing covered his face with his hands, his eyes gradually became moist, and a wave of heat surged in his chest.
Three years and more than a thousand days and nights of hard work finally paid off at this moment.
He finally found the right direction and was on the right path.
Others could not hide their excitement.
Everyone is getting ready to celebrate.
Suddenly, a high-frequency chirp erupted from the loudspeaker, instantly filling the entire control room.
Everyone looked at each other, wondering what happened.
Obviously, something must have happened.
And it happened in Zhang Li's brain.
Wen Renlong suddenly pointed at the computer screen and exclaimed: "Look, the neuron signals have changed."
Chen Yiqing was the first to look over and saw that the matrix images became denser, more precise, and larger in scope.
Everyone looked at me and I looked at each other, feeling a little surprised and uncertain for a moment.
"What's going on?" Everyone asked the same question in their eyes.
Everyone looked at Chen Yiqing, waiting for his answer.
Chen Yiqing suddenly looked at the robotic arm on the monitor, as if he remembered something.
His eyes kept wandering between the two displays, and he was lost in thought.
After a while, he finally woke up as if waking from a dream, and started shouting excitedly.
"Oh my god, have you noticed?"
"Her brain has begun to assimilate the robotic arm."
"What?" Everyone looked at him in shock.
"Why can't I understand? What does assimilation mean?" Wang Dali asked with a confused look on his face.
He asked everyone's thoughts, and others nodded.
Chen Yiqing waved his arms excitedly, trying hard to search for words in his brain, and explained.
"It's like this. The way the human brain processes information is similar to a distributed coding principle."
"For example, if a person is blind, the neurons in his brain that process eye images will lose their original purpose, but the brain will not leave them idle, but will use them to Processing information from sound.”
"In this way, the number of neurons processing sound information is greatly increased, making the blind person more sensitive to sound."
"So you understand why the hearing of blind people is often sharper than that of normal people."
"But what does this have to do with brain-computer interface?" Wang Dali was still confused.
"Listen to me, this plasticity of the brain leads to humans' powerful adaptability and learning abilities."
Chen Yiqing continued: "When Lily was unable to use her arms to operate, the external conditions changed, and the brain made appropriate adjustments and learned to use the robotic arms to play games."
"At this time, it is no longer her arm that is moving, but the neurons directly control the movement of the robotic arm."
"The brain learned this process and assimilated the robotic arm into her neuronal body image, and the robotic arm became an extension of her body."
"You can try it. Put a table of food, such as rice, porridge, soup, and steamed buns, and poke it with your finger. By feeling the difference in strength, you can clearly identify different foods."
"Then, you can try it, close your eyes, take a chopstick, and poke at the food as well."
"You can also identify these foods by the strength you feel with chopsticks. For example, soft ones are rice, hard ones are steamed buns, watery ones are soup, thin ones are porridge, etc."
"In this case, your chopsticks, in your brain's imagination, become a part of your body."
"The same is true when eating. Chopsticks replace your fingers, or, as a tool, the movements of the chopsticks are integrated into the movements of your hands and become an extension of your body."
"In the brain's eyes, it uses chopsticks the same way it uses your arms and fingers."
"That's why humans can use all kinds of tools and learn so many skills."
"Just like table tennis and football players, they use the racket or kick the ball for a long time. The racket and football become an extension of his body, replacing his hands and feet to sense the world."
"This is the legendary ball feel."
"Going deeper, it's like the swordsman in the movie. After using the sword for a long time, it has become an inseparable part of him. Even if he closes his eyes, he can sense different forces through the sword and make different responses."
Wang Dali's eyes widened in surprise: "It seems like this is really the case. If you don't tell me, I haven't discovered it yet."
"It turns out that the peerless swordsman and the international football champion became so awesome through long-term training and made tools and weapons a part of their bodies."
As he spoke, a light suddenly burst out from his eyes.
"According to this, if a paralyzed patient is replaced with a prosthetic limb, wouldn't it be possible to use the prosthetic limb as a normal body through the brain-computer interface?"
Chen Yiqing smiled and nodded: "In theory, this is true, but in reality it is a bit far away, but this is the direction we are working towards."
"Look, look, Lily is getting better and better at playing games. Her performance with the robotic arm has already surpassed that of the monkey."
Wen Renlong's cheers came over, interrupting the conversation between the two.
Wang Dali couldn't help but grin: "Aaron, then you have to thank Lily for helping you avenge your shame."
When Wen Renlong heard this, his face suddenly darkened and he shouted angrily.
"Well, who doesn't know how to cheat? Sooner or later, I will also cheat the Second Monkey."
"Hahaha~"
Everyone present laughed out loud, and the laboratory was instantly filled with happy air.
