Researchers mapped a tiny mouse brain section in detail

Scientists have created the most detailed map ever of a small section of a mouse brain, revealing intricate neural connections and paving the way for deeper understanding. Researchers analyzed a brain section the size of a grain of sand, mapping 84,000 neurons and half a billion synapses over nine years with over 150 researchers. This map links brain structure and function, showing how neurons communicate. This groundbreaking connectome, publicly available, could advance understanding of brain diseases and inform AI development. The project involved 22 institutions and used AI and human analysis to reconstruct the complex neural network.
