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 Insights - The article discusses significant advancements in brain-computer interface (BCI) technology, particularly in decoding Chinese language brain signals, which is notably more complex than English due to the higher number of phonemes involved [1][2]. Group 1: Technological Breakthroughs - Shanghai Yansi Brain AI Research Institute has collaborated with Huashan Hospital to achieve breakthroughs in BCI, enabling real-time display of intended Chinese phrases from brain activity [1]. - The BCI technology developed by Yansi Brain utilizes a multi-region collaborative decoding technique and a large intracranial EEG dataset, achieving over 83% accuracy in recognizing Chinese consonants and over 84% in recognizing vowels, marking a leading position in the industry [2]. Group 2: Clinical Applications - The advancements in BCI technology are expected to benefit patients with speech impairments, such as those suffering from amyotrophic lateral sclerosis (ALS) and stroke, by restoring their ability to communicate [1][2]. - The technology also holds potential for broader applications, including controlling intelligent devices through thought and interacting with the metaverse [2]. Group 3: Implantation Techniques - The founder of Brain Tiger Technology emphasizes the importance of balancing functionality and minimizing damage in invasive BCI techniques, opting for flexible electrodes implanted beneath the dura mater to reduce brain damage while obtaining higher quality brain signals [3].
