The researchers completed a 20-year project to map the entire nervous system of Drosophila and understand its functioning. The newly released “connectome” data reveals all 124 million contact points in the Drosophila nervous system. This research was carried out in collaboration with multiple institutions, aiming to reveal the mechanisms of operation in insect nervous systems through whole-brain imaging techniques.
