意念下棋 科幻成真(科技瞭望)
Core Viewpoint - The successful initiation of China's first invasive brain-computer interface (BCI) clinical trial marks the country as the second globally, after the United States, to enter this phase of clinical testing [3][4]. Group 1: Clinical Trial Overview - The clinical trial is a collaborative effort involving the Chinese Academy of Sciences' Center for Excellence in Brain Science and Intelligence Technology, Fudan University Huashan Hospital, and related enterprises [3][4]. - The research team progressed from animal testing to human trials, ensuring the technology's maturity, safety, and functional effectiveness, achieving a breakthrough from laboratory to clinical application [3][4][5]. Group 2: Technical Innovations - The BCI system utilizes a minimally invasive "embedded" surgical method, requiring only a small recess in the skull rather than full craniotomy, which reduces recovery time and infection risks [7][8]. - The flexible neural electrodes developed are significantly smaller and more flexible than existing products, such as those from Neuralink, with a cross-sectional area only 1/7 to 1/5 of Neuralink's electrodes, minimizing tissue damage and inflammatory responses [7][8][9]. Group 3: Patient Experience and Outcomes - A 37-year-old male participant, who lost all four limbs due to an accident, successfully used the BCI to play chess and racing games, achieving a performance speed comparable to that of able-bodied individuals [3][9]. - After just 2-3 weeks of adaptive training, the participant was able to type, send messages, and play computer games, regaining a sense of "hand" functionality and reconnecting with the world [9][10]. Group 4: Future Prospects - The project team plans to enable the participant to control robotic arms for physical tasks such as grasping and holding objects, expanding his capabilities in daily life [10]. - The BCI system is expected to assist individuals with complete spinal cord injuries, upper limb amputations, and amyotrophic lateral sclerosis in regaining motor functions and improving their quality of life once it receives regulatory approval for market entry [10].

Core Viewpoint - The latest research from Chinese scientists demonstrates that a new generation of visual prosthetics, utilizing brain-machine interface technology, not only restores visible light vision in blind animals but also expands their visual capabilities, offering new possibilities for restoring vision in blind patients [1][4]. Group 1: Research and Development - The research was conducted by a collaborative team from Fudan University and the Shanghai Institute of Technical Physics, with results published in the journal Science [2]. - The team developed the world's first visual prosthetic with a broad spectral coverage range (470-1550nm), enabling blind animal models to regain visible light vision and perceive infrared light, thus achieving "super vision" capabilities [4][5]. - The TeNWNs retinal prosthetic has the highest known photogenerated current density and the widest spectral coverage for visual reconstruction and expansion, spanning from visible light to near-infrared [5][8]. Group 2: Mechanism and Functionality - The TeNWNs prosthetic replaces degenerated photoreceptor cells in the retina, converting light signals into electrical signals, effectively activating surviving retinal neurons [8]. - The prosthetic is self-powered and does not require external devices, successfully allowing blind mice to perceive visible light [8][10]. - Experiments on non-human primate models showed no adverse rejection reactions after six months, laying a foundation for future clinical applications [10]. Group 3: Ethical Considerations and Future Directions - The dual characteristics of the prosthetic, combining "bionic restoration" and "functional expansion," avoid the risks associated with invasive brain surgeries while pushing the limits of human natural vision [10]. - Current medical ethics constraints prevent the research from entering clinical trial phases, but the technology holds promise for enabling blind individuals to experience vision and potentially surpass physiological limits [10]. - The research team aims to assist blind patients through both biological prosthetic materials and gene therapy, addressing different stages of blindness [11].
