"This is the neurological principle behind the brain-computer interface. As long as we detect the neural signals corresponding to the behavior and record them as a database, we can convert these biological signals into electromechanical signals and successfully drive the mechanical device to make the same action.

"

These words were simple and clear, and Wang Dali understood them instantly.

He leaned back in his chair, enjoying the feeling of knowledge flowing through his brain. He looked extremely intoxicated and shook his head as he spoke.

"It's so well said that a layman like me can understand it immediately."

"I just realized today that there are so many similarities between the brain and the computer."

"The nervous system is like a circuit, spread throughout the body, controlling the muscles of the body and making every movement."

"The computer is a self-aware controller. It even programmed its own control program, compiled it into electrical signals, and transmitted them to every part of the body through circuits."

"That's probably what the legendary cyber robot is."

His eyes gradually became fanatical: "Actually, the principles behind the human body and machines are the same, but the forms of expression are different, and the biological systems are much more complex."

Suddenly, Wang Dali's keen sense of smell as a man in science and engineering was triggered, and he keenly perceived the key.

He suddenly raised his head, looked at Chen Yiqing, and asked a question.

"So, how do you convert raw brain activity into digital signals?"

Bang bang bang!

Chen Yiqing applauded enthusiastically: "Good question."

"That's exactly the point. Early on, many thought this was an insurmountable hurdle."

"Think about it, biological nerve signals and alternating current signals are completely different things. How can we convert between the two easily?"

"After some hard work, scientists discovered..."

"In fact, the answer to the question is simple."

"Neuronal electrical signals are a kind of data. As long as it is data, I mean, any data, it can be statistically calculated using simple algorithms and simulated."

Having said this, Chen Yiqing looked at Wen Renlong and praised him greatly.

"This requires the use of algorithmic capabilities. With the help of Aaron, we completed this work."

"Of course, the game he played for the monkey before was also the result of his programming. It can be said that Aaron fully enjoyed the god-like treatment of being overthrown."

Wen Renlong had already shown a proud smile, but after hearing the next sentence, the smile instantly solidified on his face.

Chen Yiqing continued to flip through the ppt, displaying the entire algorithm diagram on the screen.

"We used a multiple linear regression algorithm that linearly aggregates the electrical activity generated simultaneously by cortical neurons to accurately predict the monkey's hand position."

"This algorithm is able to determine the best way to measure the electrical activity of each neuron and then aggregate these weights to produce a continuous motor output signal."

"At the same time, we also put a plastic belt on the monkey's forearm with an optical fiber sensor inside, which can sense the movement of the monkey's arm."

"As the monkey moved its arm, we recorded the position of the wrist and compared it with the monkey's neuron signals at the beginning of each movement."

"That's it, on one side is the prediction of the monkey's arm movement by the monkey's neuron signal, and on the other side is the corresponding neuron signal when the monkey's arm moves."

"By comparing the two sets of data, we can derive a multivariate linear equation describing the level of correlation between neuronal signals and the monkey's arm movements."

"Then we can improve the algorithm so that it can translate the electrical activity of neurons into action trajectories that change over time."

"Moreover, after a long period of algorithm improvement, the coefficient values ​​have become more and more stable and have reached the optimal level."

"To some extent, this algorithm can artificially recreate complex neurophysiological tasks normally performed by the spinal cord."

"After extensive training, these neural electrical signals can eventually be used on mechanical devices to reconstruct the movement trajectory of the monkey's wrist, thereby realizing the monkey's hand movement."

"The only regret is that this algorithm can only be used to predict motion parameters for the time being."
