Today, the Center for Excellence and Innovation in Brain Science and Intelligent Technology of the Chinese Academy of Sciences announced new developments in the second invasive brain-computer interface clinical trial carried out by the center in cooperation with domestic research institutions and medical institutions. This clinical trial achieved a major technical shift from two-dimensional screen cursor control to three-dimensional physical world interaction. A middle-aged male patient underwent this brain-computer interface clinical trial. Due to an unfortunate fall, the patient was quadriplegic due to a spinal cord injury in 2022. After more than a year of recovery, the condition did not improve, leaving only the head and neck to move. In June 2025, the patient implanted a brain-computer interface system developed by the research team. At first, after 2 to 3 weeks of training, the patient was able to control electronic devices such as computer cursors and tablets with ideas. This was also the level of behavior achieved by the implant during the research team's first clinical trial of an invasive brain-computer interface. In order to further improve the implanters' ability to interact with the surrounding environment, the research team successfully expanded the brain-computer interface application scenario from a two-dimensional screen to a three-dimensional physical world through the introduction of more new technologies on this basis. At present, the system has enabled users to achieve an operation speed similar to that of ordinary people using mobile phones and computers through brain “thoughts,” as well as the ability to initially control an intelligent robot.
