Digital Fruit Fly Walks: Whole-Brain Emulation Drives a Virtual Body
Researchers demonstrated an embodied whole-brain emulation of an adult fruit fly using the FlyWire connectome, with 125,000 neurons and 50 million synapses driving walking and feeding in a simulated body powered by NeuroMechFly v2 and MuJoCo, achieving about 95% motor-prediction accuracy; the work uses a biological connectome replica rather than reinforcement learning and aims to scale to mice, advancing neuroscience and AI.
