China Education Equipment Purchasing Network News: According to Tencent Technology's recent news, the British New Scientist magazine reported that in the laboratory of Zhejiang University in China, a monkey can control the robotic arm through the brain to receive a drink as a reward. What the experimental monkey didn't know was that a robot arm not far from it mirrored the movement of its fingers. This robot arm obtained instructions from a chip implanted in the monkey's brain.
Zheng Xiaoxiang (transliteration) of the Brain-Computer Interface Research Group of Zhejiang University and colleagues recently announced that they successfully captured and deciphered the signals of the monkey brain, and transformed the monkey's thinking into real-time mechanical finger movements through a chip implanted in the monkey brain.
Zheng Xiaoxiang pointed out that two sensor chips were implanted in this experimental monkey called "Jian Hui" to monitor 200 neurons in its motor cortex. However, this is enough to accurately explain the monkey's movement and control the robotic arm.
Humans have used electrodes to control prosthetic limbs. Zheng Xiaoxiang said that this research focuses on the movement of the robotic arm instructed by the brain of the experimental monkey. She said: "Finger movement is at least related to hundreds of thousands of neurons in the brain. At present, we only analyze simple movements and actions based on 200 neurons. Of course, the brain of the experimental monkey can generate some simple instructions that require real fingers. To achieve complex movements. "
