Core Viewpoint - The article highlights the successful implementation of China's first invasive brain-computer interface (BCI) clinical trial, marking the country as the second globally to enter this phase of BCI technology [1][3]. Group 1: Clinical Trial Details - The subject of the trial is a male who lost all four limbs due to an electric shock accident. Since the implantation of the BCI device in March 2025, he has achieved functionalities such as playing chess and racing games within 2-3 weeks of training, reaching a level comparable to that of an average person using a computer touchpad [3]. - The BCI system aims to improve the quality of life for patients with spinal cord injuries and amputations through motor function replacement technology [3]. Group 2: Technological Innovations - The neural electrodes developed by the Chinese Academy of Sciences are the smallest and most flexible in the world, with a cross-sectional area only 1/5 to 1/7 of those used by Neuralink, and flexibility exceeding theirs by over a hundred times, minimizing damage to brain tissue [7]. - The BCI implant has a diameter of 26mm and a thickness of less than 6mm, making it the smallest brain-controlled implant globally, about half the size of Neuralink's product. This allows for a less invasive surgical procedure, reducing risks and recovery time [10]. Group 3: Surgical Precision - The success of the surgery relies on precise localization and implantation of the electrodes. Various brain function localization methods were employed, including functional MRI and 3D modeling, to create a detailed functional map of the patient's motor cortex, ensuring accurate implantation [11]. Group 4: Future Applications - The project team plans to enable the subject to use a robotic arm for physical tasks such as grasping and holding objects. Future developments will also include controlling complex physical devices like robotic dogs and intelligent agents to further expand the subject's capabilities [12].
