An adult fruit fly brain has been mapped—human brains could follow

Scientists have created the most sophisticated connectome to date, mapping the brain of a fruit fly larva. This groundbreaking achievement involved imaging 5,000 neurons and tracing 3.7 million connections between them. The connectome reveals how the fly's brain is organized and functions, shedding light on complex behaviors like flying, flirting, fighting, and forming long-term memories. This development could lead to better understanding of human brains and potential treatments for neurological disorders.
