Researchers understand the structure of brains and have mapped them out in some detail, but they still don't know exactly how they process data — for that, a detailed "circuit map" of the brain is needed.
Now, scientists have created just such a map for the most advanced creature yet: a fruit fly larva. Called a connectome, it diagrams the insect's 3016 neurons and 548,000 synapses, Neuroscience News has reported. The map will help researchers study better understand how the brains of both insects and animals control behavior, learning, body functions and more. The work may even inspired improved AI networks.
