brain-computer interface is a disruptive technology that combines biotechnology and information technology. Its technology research and development and implementation are a complex system engineering. Recently, the country's first interventional brain-computer interface independently developed by my country successfully completed animal testing in Beijing. The interventional brain-computer interface tested this time was led by the scientific research team of Professor Duan Feng from the School of Artificial Intelligence of Nankai University and jointly developed with Shanghai Xinwei Medical Technology Co., Ltd. The success of this test marks that my country has reached the international advanced level in the field of brain-computer interface and interventional robot research.
For the first time, my country has implemented an interventional brain-computer interface in the brain of sheep.
This trial is the first time in China that has achieved an interventional brain-computer interface in the brain of sheep. It has made breakthroughs in core technologies such as interventional EEG electrodes and intravascular EEG collection. The development of neurointerventional devices such as stents and catheters has been completed, which has solved the shortcomings of traditional invasive brain-computer interfaces causing irreversible damage to the brain. has filled the gap in the field of interventional brain-computer interfaces in China, and is instrumental in promoting the field of brain science in my country. development is of great significance.
brain-computer interface technology can directly convert the signal activity of the cerebral cortex into computer instructions to control external devices without relying on the peripheral nervous system and muscle tissue. For patients with severe motor dysfunction ( stroke, , ALS, , etc.), brain-computer interfaces can help them independently control external devices, restore some movement abilities, and improve their quality of life.
Surgery scene
Traditional brain-computer interfaces are divided into invasive brain-computer interfaces and non-invasive brain-computer interfaces. Invasive brain-computer interfaces require craniotomy or drilling through the skull to implant EEG sensors into the brain. For example, Musk's Neuralink brain-computer interface needs to be implanted directly from the skull, which may cause long-term inflammation of the patient's brain. Although non-invasive brain-computer interfaces are not harmful to people, the EEG signals are weak and the recognition accuracy and real-time performance are limited.
The interventional brain-computer interface technology , led by Professor Duan Feng's scientific research team, only requires minimally invasive surgery similar to heart bypass surgery to achieve brain-computer connection . The scientific research team used neurointerventional technology to treat stroke . After implanting the EEG sensor through the vein into the brain areas such as the motor cortex and visual cortex, the neural stent expanded and squeezed the electrodes against the blood vessel walls close to the brain. Thus, the corresponding brain area signals are obtained. The biggest advantage of technology is that it does not require skull drilling or craniotomy to obtain EEG signals, and the entire surgical implantation process of can be completed within two hours.

The test finally completed the sensor implantation in the sheep's cerebral blood vessels and successfully collected the brain electrical signals. This interventional brain-computer experimental study carried out in the brains of animals shows that can improve the functional independence of people with severe paralysis caused by brain, spinal cord, peripheral nerve or muscle dysfunction, and can effectively treat epilepsy, sleep disorders, and Parkinson's disease. It is of great significance in diseases such as and , and the future market prospects are broad.
In recent years, School of Artificial Intelligence of Nankai University has achieved a number of representative research results: published papers in the main journal of SCIENCE, selected as "China's Top Ten Scientific and Technological Progress in Intelligent Manufacturing" for two consecutive years, Wu Wenjun First Prize of Artificial Intelligence Natural Science Award Award (the only one this year), the fifth Chen Hanfu Award, the first prize of Tianjin Natural Science Award, etc. The college has cutting-edge research teams in multiple directions such as " artificial intelligence +", "+robotics" and "intelligence+automation", and has 2 of the first batch of think tank experts from the Artificial Intelligence Society. The first-class teaching staff provides a strong personnel guarantee for strengthening talent training. It "feeds back" high-level scientific research results into teaching, broadens students' horizons, improves their scientific research innovation awareness and comprehensive practical ability, and further improves the quality of talent training.
