Click on the blue word above to pay attention to us! A representative team from Tianjin, China, engaged in brain computer interface research, combined with typical practical applications, is opening up unlimited possibilities for brain inspired research in the medical field.when China launched tiangong-2 space laboratory in 2016, one of its goals was to test the adaptability of non-invasive brain computer interface (BCI) technology to the space environment.Chinese astronauts have successfully completed the first global test, which provides an important benchmark for comparing the performance of BCI in earth and space.and the brain computer interface system used in this experiment was developed by the neural engineering team of Tianjin brain science and brain like research center.the first international on orbit brain computer interaction experiment (picture @ cctv-cctv4) Tianjin brain science center, relying on the construction of the Institute of medical engineering and translational medicine of Tianjin University and the affiliated Huanhu hospital, focuses on the research fields of brain science and cognitive science, neural engineering and vitality interaction, brain like intelligence theory and medical application, especially in the direction of noninvasive brain computer interface To accelerate the transformation and industrial application of this technology in clinical medicine, aerospace and daily life.Professor Ming Dong, director of the center of Tianjin University's Institute of medical engineering and translational medicine, Tianjin University, said that the brain computer interface bypasses the inherent peripheral nerve and muscle tissue of the human body, connecting the brain directly with the outside world, thus opening up a new communication channel for people's idea expression."heart is action."Professor Mingdong described the application prospect of brain computer interface technology," using human brain's mind to control external terminal can help patients regain motor ability, and in the future, robots can become our separate body."Professor Mingdong's optimistic outlook comes from the research accumulation of the team rooted in the field of brain science and neural engineering for more than ten years.the noninvasive brain computer interface technology based on scalp EEG control is safe, convenient and efficient.he said, "it's time to bring these technologies into the core areas for scale application."in general, there are three important indicators to evaluate the performance of BCI system, which are the recognizable accuracy of brain control signal, the information transmission rate of the system and the size of single controllable instruction set.the young team of Tianjin University led by Professor Mingdong is the current international record holder of the three performance indicators.in 2016, the team adopted the dynamic stop strategy to realize the simulated online BCI experiment with the highest information transmission rate so far, supporting the adaptive collection of enough EEG signals for accurate measurement.in 2018, the developed discriminative canonical pattern matching algorithm realized the efficient decoding of sub microvolt event related potential for the first time in the world, thus improving the recognizable accuracy of EEG signals by an order of magnitude.in 2019, a high-speed BCI system was built to control 108 instructions of the full keyboard for the first time, and its instruction set size was about three times that of the traditional BCI system.the weak visual stimulation paradigm and its discriminative typical pattern matching not only expand the astronaut's operational ability in the space environment, but also the BCI technology developed by the team of Tianjin brain science center is also used for the rehabilitation treatment of stroke patients. compared with the traditional methods, the team combined BCI technology with functional electrical stimulation technology to develop an artificial neural rehabilitation robot system for whole limb stroke rehabilitation training. the system can realize the cortical and muscle activities caused by human subjective motor intention, and significantly improve the nerve control ability of the affected limb. now a series of neural rehabilitation robots developed by the team have been successfully applied in many hospitals. "shengong-1" artificial neural rehabilitation robot in the future, Tianjin brain science center will focus on the "clinical + scientific research" dual center innovation driven mode, and further gather and organize the dominant forces in related fields to carry out collaborative innovation in brain science and brain like research, diagnosis and treatment of brain diseases and clinical rehabilitation. this young and energetic Chinese team is striving to become a world-class brain science and neural engineering research center with distinctive characteristics.
