Research progress on implantable brain-computer interface.
On January 16, Zhejiang University announced the scientific results of the “Double Brain Project”. Volunteers with implanted electrodes can accurately control external robotic arms and manipulators to achieve three-dimensional space movements using signals from the cerebral motor cortex; at the same time, It is feasible for elderly patients to use complex brain-computer interface for complex and effective motion control.
The “Brain Brain Project” is the first domestic clinical clinical implantable brain-computer interface completed by the brain-computer interface team of Qiushi College of Zhejiang University and Neurosurgery of the Second Affiliated Hospital of Zhejiang University Medical College. the study. By implanting Utah array electrodes in the brain of a high paraplegic volunteer, the 72-year-old patient successfully controlled the three-dimensional movement of the robotic arm with ideas, and completed a series of important upper limb functional movements such as eating, drinking, and shaking hands.
The success of this research indicates that China’s brain-computer interface technology has become one of the internationally advanced in clinical translation and application research.
Mr. Zhang, a volunteer who accepted the clinical translational study of brain-computer interface, is a 72-year-old retired teacher. He suffered from a serious car neck injury 2 years ago and became a high paraplegia. patient.
In August 2019, Mr. Zhang underwent the operation of Zhang Jianmin, the director of the Department of Neurosurgery of the Second Hospital of Zhejiang University, and successfully completed the first domestic craniotomy and the implantation of Utah array electrodes into the motor cortex that controls the movement of the right upper limb. surgery. After 4 months of rehabilitation training, Mr. Zhang realized that he controlled the feeding of the robotic arm with his mind.
In the video released by the Second Hospital of Zhejiang University, a robot arm stands next to Mr. Zhang ’s bed. The staff puts a cup filled with fritters next to the robot. Open your fingers, hold the cup, watch the robotic arm move the cup towards your mouth, and adjust the angle of the mouth of the cupDegrees, and finally got the fritters. In addition, Mr. Zhang also successfully controlled the robotic arm to drink cola and play mahjong with his mind.
