Safer than traditional invasive methods! China's first self-developed interventional brain-computer interface animal test was successful

It was learned from the official website of Nankai University that my country's first domestically developed interventional brain-computer interface has successfully completed animal experiments in Beijing. The success of this experiment marks that my country has reached the internationally advanced level in the field of brain-computer interface interventional robot research.

It is reported that this experiment is the first time in China to realize an interventional brain-computer interface in a sheep's brain. It has made breakthroughs in core technologies such as interventional EEG electrodes and intravascular EEG acquisition, completed the development of neurointerventional device products such as stents and catheters, and solved the problem of traditional invasive brain-computer interfaces causing irreversible damage to the brain area, filling the gap in the domestic interventional brain-computer interface field.

According to reports, traditional brain-computer interfaces are divided into invasive brain-computer interfaces and non-invasive brain-computer interfaces. Invasive brain-computer interfaces require the implantation of EEG sensors into the brain through craniotomy or drilling through the skull. For example, Musk's Neuralink brain-computer interface needs to be implanted directly from the skull, which may cause long-term inflammation in the patient's brain.

my country's self-developed interventional brain-computer interface technology can achieve brain-computer connection through a minimally invasive surgery similar to heart bypass surgery.

The research team used neurointerventional technology to treat stroke. After implanting EEG sensors into the motor cortex, visual cortex and other brain areas through the veins, the neural stent expanded and squeezed the electrodes against the blood vessel walls close to the brain, thereby obtaining signals from the corresponding brain areas.

The biggest advantage of this technology is that it can obtain EEG signals without skull drilling or craniotomy, and the entire surgical implantation process can be completed within two hours.
