Overview
- Eon reports a neuron‑by‑neuron reconstruction using FlyWire data with roughly 125,000 neurons and about 50 million synapses.
- The emulated brain controls a NeuroMechFly body within the MuJoCo physics engine, creating a closed loop from sensory input to motor output.
- In the virtual environment, the fly exhibits walking, turning, grooming and food‑seeking without programmed rules or training.
- The effort builds on a 2024 Nature model led by Philip Shiu that modeled the adult Drosophila brain but did not control a body.
- No peer‑reviewed paper or independent validation has appeared, and Eon targets a mouse brain next with longer‑term human‑scale ambitions amid open scientific and ethical questions.
