SI helps compile a complete map of a male fruit fly's brain: 166 thousand neurons and 125 million connections

SI takes on the most routine part of neuroscience, hand-labeling billions of pixels, and thereby brings closer the moment when we can read the "wiring diagram" of a whole brain. First flies, then the mouse and possibly humans.
The HHMI Janelia Research Campus, together with Google Research, the MRC LMB laboratory and Cambridge, published the first complete proofread map of the male fruit fly's nervous system: more than 166 thousand neurons and 125 million synapses, including the central brain, optic lobes and ventral nerve cord. It is the largest brain map by neuron count to date. Flat electron microscope images were turned into three-dimensional neurons by Google's neural networks (flood-filling networks and the PATHFINDER system, fine-tuned on synthetic neurons). For comparison: in 2020 the proofread map of half of a female's brain contained 25 thousand neurons. The data is open to everyone.
