Thank CTOnews.com netizens Rimi Ishihara for happy, Hello _ rabbit, suitcase clues delivery! CTOnews.com, May 29, at the "brain-computer Interface Innovation and Development Forum" held today, Zhao Zhiguo, chief engineer of the Ministry of Industry and Information Technology, said that with the joint efforts of the industry, China has formed a whole industry chain of brain-computer interfaces covering the basic layer, the technical layer, and the application layer, and has landed applications in medical, educational, industrial, entertainment and other fields.

He said: the Ministry of Industry and Information Technology will regard the brain-computer interface as an important direction for cultivating the future industrial development, strengthen the exploration of the application scenarios of the brain-computer interface, and accelerate the vigorous development of the brain-computer interface industry.

In addition, Zhao Jizong, academician of the Chinese Academy of Sciences, also pointed out that there are the following problems and challenges in the clinical application of brain-computer interfaces:

1. The brain has 80 to 100 billion neurons. It is very difficult to analyze the data collected by the brain-computer interface: which signals are useful and which are not, and little is known about how the signals interact.

two。 The implantable electrode has the risk of operation, the implanted electrode may have immune reaction or infection, and glial scar tissue is formed around the electrode to attenuate the nerve signal.

3. The EEG obtained by non-invasive method is of poor quality and is vulnerable to external interference.

4. Brain-computer interface security: if some harm or threat to society is detected, whether corresponding measures should be taken.

5. To solve the above problems, physicians, scientists, engineers, ethicists, government supervision agencies and patient rights groups need to work closely to promote the healthy and rapid development of brain-computer interface.

The Pexels brain is regarded by many researchers as the most complex organ in the human body. In the brain, more than 100 billion neurons form more than 100 trillion neuronal connections, which makes it a worldwide problem to "understand" the brain.

Brain-computer interface, sometimes called "brain port" direct neural interface or "brain-computer fusion perception" brain-machine interface, is a direct connection between human or animal brain (or brain cell culture) and external devices, and is a communication system that does not rely on normal output pathways composed of peripheral nerves and muscles. (CTOnews.com Note: in this definition, the word "brain" refers to the brain or nervous system in an organic life form, not just "mind". "computer" means any device for processing or computing, which can range from simple circuits to silicon chips.)

In the case of an one-way brain-computer interface, the computer either accepts commands from the brain or sends signals to the brain (such as video reconstruction), and the two-way brain-computer interface allows two-way exchange of information between the brain and external devices.

In recent years, a number of research teams, such as the University of Pittsburgh and the California Institute of Technology, have successfully used the intrusive brain-computer interface to allow paralyzed patients to use their brains to directly control the manipulator to complete grasping and stirring movements. the brain waves are directly converted into text and voice.

In China, many colleges and research institutions have made exploratory achievements in the field of brain computers. The world's first non-human primate intrusive brain-computer interface experiment was successful in Beijing on May 4. the experiment realized an intrusive brain-computer interface brain-controlled robotic arm in the brain of monkeys, which is of great significance in promoting research in the field of brain science. it marks that China's brain-computer interface technology has entered the leading ranks of the world.

On April 4 this year, the Ministry of Science and Technology issued a public announcement on soliciting opinions on the "measures for Ethical Review of Science and Technology (trial)", which mentioned the algorithm model of public opinion, brain-computer interface and so on.

In addition to the trial announced by Nankai University, the team of Zhejiang University has carried out relevant clinical research in 2020. With the help of brain-computer interface technology, a 72-year-old man with complete quadriplegia at that time could use signals from the cerebral motor cortex to accurately control external manipulators and manipulators to complete movements such as eating and shaking hands, according to Zhejiang University.

Although progress has been made, there are still many obstacles to be overcome in brain-computer interface technology, including the obstacles of solving complex brain waves, the technical obstacles of multidisciplinary interaction, and so on.

In addition, the future application of brain-computer interface technology also involves legal, ethical and regulatory issues. Some experts have suggested that in the management and control of brain-computer interface technology, it can be managed according to the method of medical devices with reference to international common practice at the initial stage of development, and at the same time prohibit the transmission of brain-computer interactive data on the Internet, prohibit long-distance program control, and maximize the prevention of hackers. Prevent potential risks.
