Recently, Zhao Zhengtuo and Li Xue from the Center for Excellence and Innovation in Brain Science and Intelligent Technology of the Chinese Academy of Sciences, together with Huashan Hospital affiliated to Fudan University and related enterprises, carried out the second clinical trial of invasive brain computer interface, which was declared successful. After implantation of relevant systems in the brain, patients with high paraplegia can freely move electric wheelchairs and command robotic dogs to complete daily tasks such as retrieving objects through mental manipulation. This marks that China's invasive brain computer interface technology has successfully moved from the virtual interaction stage in the laboratory to the application in real life scenarios, providing new possibilities for the reconstruction of life abilities for patients with motor dysfunction.
