    Google just mapped an entire male fruit fly brain

    Google Research and HHMI Janelia just unveiled the complete wiring diagram of a male fruit fly's brain and central nervous system. By combining AI reconstruction algorithms with human verification, the team mapped over 166,000 neurons and 125 million synapses—the largest connectome to date. It fully traces neural pathways from sensory perception to motor control, and researchers can explore the whole model right now via Neuroglancer.

    Google unveils ZAPBench to forecast whole-brain neural activity

    Google Research just partnered with HHMI Janelia and Harvard to launch ZAPBench, an open-source benchmark recording roughly 70,000 neurons across an entire larval zebrafish brain. Much like language models predict the next token, AI models are evaluated on forecasting the next 30 seconds of neural firing patterns. Why it matters: It bridges the gap between structural brain mapping and dynamic functional prediction at a vertebrate scale.
