Science fiction becomes reality in Nanjing, where brain-computer interfaces (BCIs) are transforming lives. Paralyzed patients regain movement with mind-controlled exoskeletons, while amputees play piano using bionic arms—all powered by neural signals.     At Nanjing’s recent BCI conference, breakthroughs in AI, neuroscience, and materials science converged, sparking major industry deals. A standout innovation: China’s first domestically developed deep-brain recorder and stimulator, enabling precise neural signal capture and targeted therapy.     Nanjing is uniting universities, hospitals, and tech firms to dominate the BCI frontier. As Chinese Academy of Sciences academician Cheng Heping declared: “If you’re in BCIs, Nanjing is the place to be.” The future of mind-powered tech starts here.
