Safer than traditional Invasions! The first animal experiment of self-developed interventional brain-computer interface was successful in China

June 28, according to the official website of Nankai University,The first interventional brain-computer interface developed by China has been successfully tested on animals in Beijing.The success of this experiment indicates that China has reached the international advanced level in the research field of brain-computer interface intervention robot.

It is understood that the trial was the first domestic sheep brain implement intervention brain-machine interface, break through the intervention eeg electrode, intravascular eeg acquisition, such as the core technology, complete support, catheter, such as nerve intervention equipment product development, solve the traditional invasive brain-computer interface cause irreversible damage to the brain, fill in the blank in the field of national intervention brain-machine interface.

According to the introduction, the traditional brain computer interface is divided into invasive brain computer interface and non-invasive brain computer interface. Invasive BcI involves inserting eeg sensors into the brain through craniotomy or drilling through the skull,Such as Musk's Neuralink brain-computer interface, which requires implantation directly from the skull, can lead to long-term inflammation in patients' brains.

However, the interventional BRAIN-computer interface technology developed in China only requires minimally invasive surgery similar to heart bypass to achieve brain-computer connection.

Using a neurointerventional technique used to treat stroke, the team implanted electrical sensors into the motor cortex, visual cortex and other areas of the brain via a vein. The scaffold expanded and the electrodes were pressed against the walls of blood vessels near the brain to obtain signals from the corresponding areas of the brain.

The biggest advantage of this technique is that it doesn't require cranial drilling or craniotomy to get electrical signals from the brain,The procedure can be completed within two hours.
