Wearing VR glasses and holding a handle in each hand, there will be a three-dimensional image of brain neurons in a thousand revolutions. Scientists can accurately depict the direction and shape of neurons and plot them for brain neurons. A digital map.

"The total number of human brain neurons is as high as 86 billion, which is called the most complex body structure known in the universe. However, humans have been engaged in brain research for nearly a hundred years, and still have not been able to figure out how many kinds of neurons and their interactions. Relationship," said Xie Wei, dean of the Institute of Life Sciences at Southeast University.

In the recently established Institute of Brain Science and Intelligent Technology of Southeast University, the Science and Technology Daily reporter saw that researchers are using visualization software and VR equipment to reconstruct a single brain neuron.

"What do you think in your head?" is still a mystery.

Brain science research is not only a hot spot in the current international science and technology frontier, but also an "ultimate territory" for understanding nature and human beings. At present, the United States regards the three-dimensional shape and basic types of neurons as key research fields. China's "Science and Technology Innovation 2030 Major Project" has also launched "Brain Science and Brain-like Research".

Scientists have always been interested in how the brain achieves cognitive function. In the past, we only knew the connection and cognitive functions of different brain regions on the macro scale. For example, the brain core part is responsible for the daily life of human beings. The brain system is responsible for actions, emotions, memory processing, etc. The cerebral cortex is responsible for human brain. Advanced cognitive and emotional functions, etc.

However, the microscopic working mechanism of the brain is much more complicated. For example, in micro-nano, the molecular structure and signal transmission of synaptic connections are expressed. On the hundred-micron scale, local neural circuits and information coding such as cerebral cortical functional columns are expressed.

Xie Wei told the Science and Technology Daily reporter that Southeast University has cooperated with the American Allen Brain Institute to locate the frontiers of brain science and provide brain science big data resources to the world. The Institute of Brain Science and Intelligent Technology of Southeast University was established to integrate the superior resources of various disciplines, to break through the barriers of brain science research and intelligent technology, and to better promote the integration of production, learning and research.

Let the "reading mind" super power come true

"The main work we are doing now is to digitize the structure of brain neurons and build a large database of brain sciences to provide valuable data resources for biomedical research." In describing how to map 3D maps of brain neurons, Southeastern University Allen United The director of the center, Peng Hanchuan, described it as “massive big data, highly complex”.

Faced with tens of billions of neurons and massive data, if traditional neuroscience research methods and data computational analysis methods are used, the brain cannot be effectively studied. In the future, Southeast University will take advantage of the school's self-developed sensing, acquisition equipment and visualization software to take the lead in the reconstruction of brain neurons.

"Our artificial intelligence software algorithm is very efficient. It will draw a digital map of brain neurons in 3-4 days. At present, it has completed the digital reconstruction of nearly 40 neurons. It is expected to use new technology to improve efficiency by dozens of times. Hundreds of times." Peng Hanchuan said.

The brain science big data formed by the 3D map of brain neurons will provide scientific analysis for children's cognitive disorders, interventional treatment of brain diseases, regular exploration of adolescent brain development, and research on people's emotional changes.

At the Key Laboratory of the Department of Child Development and Learning Science of the Southeast University, a researcher wore a strange hat with various lines. He was testing the multimodal social sentiment evaluation system. The skin, heart rate, respiration, and EEG signals of the subjects were monitored in real time. The system will collect people's emotional changes based on brain caps, near-infrared, electrocardiograms, expression sensors, etc., and judge people's emotions in real time. On the big screen, they will smile or cry face according to emotional changes.

"With brain science big data resources, and then use a 'brain cap' sensor, you can make the 'reading mind' super power come true." Laboratory director Zheng Wenming said that the system has been tested in Nanjing Brain Hospital. It can automatically analyze people's emotional adjustment ability and sympathetic ability. At present, more than 100 children with autism and autism have been screened for early screening.
