意念说话！脑机接口临床新突破引国际权威学术期刊关注

Core Viewpoint - The article highlights a significant breakthrough in brain-computer interface (BCI) technology achieved by Shanghai YanSi Brain-like Artificial Intelligence Research Institute in collaboration with Huashan Hospital of Fudan University, enabling patients with speech impairments to communicate through thought [1][2]. Group 1: Technological Breakthroughs - The BCI technology allows real-time decoding of brain activity to display intended Chinese phrases, marking a major advancement in language decoding for patients with conditions like ALS and stroke [1]. - The research has been recognized in the prestigious journal "Nature," showcasing China's progress in invasive BCI technology, including real-time motion and language decoding capabilities [1]. Group 2: Technical Details - The decoding of Chinese brain signals is more complex than English due to the higher number of phonetic components, with over 400 compared to English's 50 [2]. - The YanSi Brain-like Institute utilizes a multi-region collaborative decoding technique and a large intracranial EEG dataset to achieve over 83% accuracy in recognizing Chinese consonants and over 84% in recognizing vowels, positioning it at the forefront of the industry [2]. Group 3: Future Applications - The BCI technology not only aims to restore communication abilities for speech-impaired patients but also has potential applications in controlling physical devices through thought, interacting with the metaverse, and generating artistic expressions from mental imagery [2]. Group 4: Implantation Techniques - The founder of Brain Tiger Technology emphasizes the challenge of balancing brain function utilization with minimizing damage during invasive BCI implantation, opting for flexible electrodes placed beneath the dura mater to enhance signal quality while reducing brain injury [3].
