Google Research, working with HHMI Janelia Research Campus and other partners, has published a complete wiring diagram of the adult male fruit fly brain and central nervous system. The map contains roughly 166,000 neurons and 125 million synapses, making it the largest neuron-count brain map published to date. It is a neuroscience resource rather than a new AI product, but it provides a much richer foundation for studying how neural circuits turn sensory inputs into actions.

The milestone has also attracted attention because an independent project, DOOMFLY, uses retained connectome data in an experimental pipeline that drives the game Doom. That demonstration is an intriguing test of real-time control, but it should not be confused with Google having created a general-purpose AI agent, a trained game-playing system, or a commercial neuromorphic platform. The official achievement is the connectome itself. The gameplay experiment is an early exploration of one possible way to interact with such data.

What Google Research published

A connectome is a map of connections in a nervous system. In this case, researchers mapped the adult male fruit fly brain and central nervous system at a level that records neurons and the synapses connecting them. Google describes the result in its official connectomics milestone announcement, alongside work published by Januszewski, Jain, and collaborators in Cell.
