大脑意念控制轮椅、机器狗……我国侵入式脑机接口临床试验实现重大突破！

Core Insights - The article highlights the successful demonstration of China's second invasive brain-computer interface (BCI) clinical trial, showcasing its ability to allow a paralyzed individual to control a smart wheelchair and a robotic dog using only their thoughts, marking a significant advancement in rehabilitation technology [1][3]. Technological Breakthroughs - The BCI system developed by the Brain Intelligence Excellence Center and related enterprises enables patients to control electronic devices like computers and tablets after a brief training period [3][10]. - The technology has evolved from controlling 2D screens to interacting with 3D physical objects, requiring precise and stable control in real-world environments [10][11]. - Innovations in neural signal extraction and compression techniques have improved the efficiency of information retrieval from the brain, enhancing BCI performance by 15% to 20% [10][11]. Patient Experience - The second clinical trial patient, who suffered from spinal cord injury, reported that controlling the devices felt as natural as moving their own limbs, with minimal delay in response [12][14]. - The BCI system has significantly enriched the patient's daily life, allowing them to perform tasks independently and reducing the burden on their family [3][12]. Future Prospects - The research team is optimistic about the future of BCI technology, envisioning applications that could restore motor and sensory functions, and even enhance capabilities beyond normal human abilities [15][18]. - Upcoming advancements include a new generation of BCI systems with increased channel capacity and improved functionality, which are expected to undergo clinical trials soon [15][16]. - The integration of artificial intelligence with BCI technology is anticipated to create more complex and capable external devices, further expanding the potential applications of this technology [16][20].
