The Innovation and Development and Application Forum of the Brain Machine Interface was held in Beijing on April 26.As one of the parallel forums of the 2024 Zhongguancun Forum Annual Meeting, the forum focuses on the latest progress of brain machine interfaces, shared scene applications in the field of medical care, explores the infinite possibilities of brain machine interfaces, and explores industrial innovation and ecological construction.
Zhao Guoguang, the dean of Xuanwu Hospital of the Capital Medical University, said at the forum that from the technical principles, brain interface is based on the collection, output, conversion and decoding of brain and machines formed by the brain and machine.Including four elements: perception, analysis, action, and feedback, that is, collect brain signals and capture neural activity; brain signal processing and decoding, transform into specific instructions; connect and control peripherals, implement function or nerve regulation; neural feedback, learn, adapt to adaptationAnd adjust.
Depending on the location of the collection signal, the brain interface can be divided into non -invasive and invasive type.Mingdong, the vice president of Tianjin University, said at the forum that the two methods are different in terms of technical routes, development logic, and application scenarios.Accurate time and space positioning, more advanced thinking decoding.
With the advancement of science and technology, the brain interface gradually moves from science fiction concepts to real life."The world's developed countries are in the field of pushing brain -machine interfaces. China's scientific research input and output in this field have gone at the forefront of the world." Gu Xiaosong, an academician of the Chinese Academy of Engineering, said in an interview that thanks to the promotion of artificial intelligence and other technologies.In the field of brain -machine interfaces, in recent years, it has developed rapidly in recent years, and its application scenarios have also been widely used, covering medical, rehabilitation, games, entertainment, education, military, etc.
The application scenario of the brain interface is first of all in the medical field.Zhao Guoguang said that the brain interface can be used for diagnosis and treatment of multiple diseases.Including spinal cord injury, epilepsy, Parkinson disease, depression, and other mental health disorders, almost all neurotic and mental diseases caused by abnormal brain network abnormalities are expected to be treated through the brain machine interface.
For example, in October 2023, Xuanwu Hospital cooperated with the School of Medicine of Tsinghua University to jointly complete the first implantation of the clinical trial of wireless minimally invasive implanted brain machine interface to help a patient paralyzed with limbs use brain electrical activity to use brain electrical activity activitiesDriven pneumatic gloves realize autonomous "brain control" drinking water.
While booming, the brain interface is also facing challenges such as technology, security, ethics, and a certain distance from large -scale use.Zhao Guoguang said that how reliable, stable, and lastingly records the electrical signals related to the function from the brain tissue, how to deepen the understanding of the brain network mechanism, when the brain machine interface is implanted more and moreIt is a problem that the brain interface is facing in the field of diagnosis and treatment.
Gao Xiaorong, a professor in Tsinghua University, said in an interview that the brain interface is an indispensable technology in the future. It is currently entering the period of technology explosion, but there are certain ethical security issues.Find a balance between the balancing, not hurt the brain.At the same time, this technology must be strictly supervised and the privacy of brain data should be performed.
"Although there are shortcomings in the application field, the brain -machine interface technology is expected to change human life in the future." Mingdong admits that the more hot the brain interface field, the more related practitioners must maintain calmness, rationality, and objective.Attitude, preventing its development, speculation, exaggeration, etc., so as to promote the healthy and orderly development of this technology.
