Google maps a male fruit fly's full brain
On September 3, 2026, Google Research, HHMI Janelia and collaborators released the first complete wiring map of an adult male fruit fly's brain and central nervous system — more than 166,000 neurons and 11,691 cell types. AI stitched millions of 2D slices into 3D neuron shapes; the map follows an earlier complete female fruit fly connectome and is meant as a public neuroscience resource. Three companion studies out the same day apply it to vision, taste and social behavior — this is connectomics research, not a Gemini product.
