CTOnews.com, March 12 (Xinhua) to most humans, the drosophila larva looks like a wriggling, rice-grained bug, but for neuroscientists, it is a complex and sophisticated biological system and a valuable object of study. Recently, a 12-year international collaborative project has finally completed a complete brain map of Drosophila larvae, revealing the structure and function of the nervous system of this tiny creature. The study, published in the journal Nature, is seen as a major breakthrough in neuroscience.

According to CTOnews.com, the complete brain map of Drosophila larvae includes all 3016 neurons and 548000 synapses (connections between neurons) in its central nervous system, which is the most complex and complete map of insects published so far. Using advanced microscope technology and computer algorithms, the scientists cut the brain of fruit fly larvae into more than 8000 ultra-thin sections and digitized the cells and synapses on each slice into three-dimensional images. They then spliced the images using artificial intelligence software to form a high-resolution, interactive, searchable and annotative brain map of fruit fly larvae.

More surprisingly, this connection group bears a striking resemblance to the neural networks used in artificial intelligence (AI). Scientists have found that there is a special type of synaptic pattern in the central nervous system of fruit fly larvae, called "jump connectivity", in which some neurons can be connected directly across multiple layers. This model is also widely used in the field of AI because it can improve the efficiency and accuracy of information processing.

Scientists say the findings suggest that there are common optimization principles or design patterns in both nature and artificial intelligence and may help us to improve existing machine learning algorithms or develop new ones.

At present, scientists have publicly shared the complete brain map of Drosophila larvae to the world, and provided a convenient online platform for interested researchers and the public to browse and analyze. They hope that this complete brain map of fruit fly larvae will become an open resource and stimulate more innovation and cooperation.

Scientists believe that by studying the nervous system of fruit fly larvae, we can reveal some basic neuroscience principles and provide clues for understanding higher levels of animal brain function. The complete brain map of Drosophila larvae is a milestone, but not the end. Scientists also plan to draw complete brain maps of adult fruit flies, other insects and even mammals, and explore similarities and differences and evolutionary relationships between different species. They believe that in the future, we will be able to build a large neural network "map library" that comprehensively and accurately reflects the mysteries of life intelligence.
