Our country has made new advances in invasive brain-computer interface clinical trials.

Today, the Center for Excellence in Brain Science and Intelligent Technology of the Chinese Academy of Sciences announced new progress made in the second invasive brain-machine interface clinical trial carried out in collaboration with domestic research institutions and medical units. This clinical trial achieved a significant technological advancement from two-dimensional screen cursor control to three-dimensional physical world interaction. The participant in this brain-machine interface clinical trial was a middle-aged male patient. Due to an unfortunate fall, this patient became paralyzed in all four limbs due to spinal cord injury in 2022. After more than a year of rehabilitation with no improvement, he was left with only movement in the head and neck. In June 2025, the patient underwent implantation of the brain-machine interface system developed by the research team. Initially, after 2 to 3 weeks of training, the patient was able to control electronic devices such as computer cursors and tablets with his thoughts, marking the first behavioral level reached by an implant recipient in an invasive brain-machine interface clinical trial conducted by the research team. In order to further enhance the patient's interactive abilities with the surrounding environment, the research team expanded the application scenarios of the brain-machine interface from two-dimensional screens to three-dimensional physical world through the introduction of new technologies. Currently, the system has enabled users to operate smartphones and computers at speeds similar to that of ordinary people through "thoughts" from the brain, as well as the ability to control humanoid robots in a preliminary manner.
