【中国青年报】90后科研伉俪“脑机”筑梦

Core Viewpoint - The article highlights the significant advancements in invasive brain-computer interface (BCI) technology led by researchers Zhao Zhengtuo and Li Xue, showcasing their successful clinical trials that enable paralyzed patients to control devices using their thoughts, thus improving their quality of life [1][3][17]. Group 1: Clinical Trial Achievements - The second clinical trial demonstrated that a patient with high-level paraplegia could control a smart wheelchair and a robotic dog using only their thoughts, marking a breakthrough in BCI applications [1][4][17]. - The patient, who suffered from spinal cord injury, was able to control electronic devices like computers and tablets within 2-3 weeks of training after receiving the BCI implant [5][17]. - The technology evolved from controlling virtual devices to interacting with physical objects, allowing the patient to navigate real-world environments [6][7]. Group 2: Research and Development Approach - Zhao and Li emphasize the importance of addressing real-life problems faced by patients rather than merely showcasing technological capabilities [8][10]. - Their research approach has shifted from basic research to focusing on practical applications that enhance patients' daily lives, driven by the needs expressed by patients [9][10]. - The team has developed a flexible electrode that is less invasive, allowing for easier implantation compared to competitors, which is crucial for patient safety and comfort [14][15]. Group 3: Future Prospects and Vision - The researchers envision that BCI technology will not only assist patients with mobility issues but could also be applied in areas such as artificial sensory restoration and treatment of neurological disorders in the future [19][20]. - They aim for BCI devices to become as ubiquitous as smartphones, ensuring that anyone in need can benefit from this technology [20][21]. - The team is committed to continuous improvement and adaptation of their technology to meet evolving patient needs and to foster collaboration with various stakeholders in the healthcare and technology sectors [16][19].
