China’s brain chip tech achieves tumor localization breakthrough

A Chinese research team has completed the world’s first clinical trial using brain-computer interface (BCI) technology to guide deep brain tumor surgery. The new device, called NeuroDepth, uses implanted microelectrode arrays to map tumors in real time, allowing surgeons to remove gliomas more precisely while protecting healthy brain tissue. In the trial, a patient regained language ability after surgery. Unlike traditional electrodes, NeuroDepth can capture signals from the cortex down to deep brain regions and monitor neurotransmitters, offering unprecedented accuracy. Researchers say the breakthrough could improve treatment of brain tumors and may later expand to restoring vision, hearing, and movement in patients.
