Beijing, February 26 (Reporter Wu Yue) The reporter learned from Tsinghua University: Recently, the team of Professor Hong Bo of Tsinghua University School of Medicine and the team of Professor Jia Wang of the Department of Neurosurgery of Beijing Tiantan Hospital affiliated to Capital Medical University successfully helped high paraplegic patients to control the movement of the computer cursor with EEG activity by using wireless minimally invasive brain-computer connection, which means that China has made new progress in the field of brain-computer interface.
On December 19, 2023, Professor Hong Bo led the team to design and develop a wireless minimally invasive implantable brain-computer interface system, and Professor Jia Wang's team performed clinical implantation surgery. The team implanted a miniature brain-computer interface processor into the patient's skull and successfully collected neural signals from the extrameningeal sensorimotor brain region. After nearly two months of training, the patient can not only drive the pneumatic gloves to grasp autonomously through EEG activity, but also control the cursor on the computer screen to move freely.
The wireless minimally invasive implanted brain-computer interface system consists of three parts: electrodes, in vivo microprocessors, and in vitro machines. The microprocessor in the body is connected to the electrodes to collect intracranial EEG signals; The in vitro computer provides wireless power to the microprocessor in the body to realize the transmission of EEG signals, and uses machine learning algorithms to "translate" the EEG signals into control instructions of external devices.
