China’s Brain Chip Tech Achieves Tumor Localization Breakthrough
A Chinese-led team has reported a breakthrough in brain-computer interface (BCI) technology after completing the first-ever clinical trial to precisely locate deep-seated brain tumors using implanted microelectrode arrays. In the world’s first trial of its kind, conducted by the Aerospace Information Research Institute of the Chinese Academy of Sciences and the First Affiliated Hospital of Harbin Medical University, a glioma patient experiencing speech difficulties due to tumor compression showed significant improvement in language ability after surgery guided by BCI technology.
The core innovation lies in the BCI device, called “NeuroDepth,” which provides real-time navigation for tumor boundary detection, enabling accurate resection while protecting healthy tissue. Unlike traditional electrodes that capture only surface signals, NeuroDepth can record activity from the cortex to deep brain regions and monitor neurotransmitters, offering more detailed data.
