　　Researchers from the Massachusetts Institute of Technology and the University of Vienna have successfully created an imaging system that reveals neural activity in the brains of living animals. This technology is the first to improve 3D imaging of the entire brain to the millisecond level, and can help scientists understand how neural networks exchange information and generate behavior. The team used a new system to simultaneously image each neuron of the worm and the whole brain activity of zebrafish seedlings, and the imaging results provided a more comprehensive understanding of neural activity.

　　"Just looking at the activity of one neuron in the brain does not clearly understand how information is processed. To understand the function of upstream neurons and understand the meaning of a given neuron activity and we need to be able to see what downstream neurons are doing." A team leader said that he is an associate professor of bioengineering, brain and cognitive sciences at MIT. Ed Boyden said. "In short, if you want to understand how information is transmitted and how it behaves, you must study the entire brain."

　　This new method helps nerves. Published on May 18 in "Nature"? It has been published in this issue. Scientists learn more about the biological basis of brain diseases. Boyden said: "I really don't know the exact collection of cells related to brain diseases." "Whole brain research can help identify neural activities related to brain diseases and open up new ideas for treatment."
