Now, for the first time, the complete brain and central nervous system of an adult male fruit fly have been fully mapped. Google Research scientists worked alongside HHMI Janelia Research Campus and the scientific community to achieve this milestone. In the social media post outlining the achievement, Google claimed that AI was used “to combine millions of 2D images into 3D neural shapes, reconstructing a record-breaking 166,000+ neurons.” That’s somewhat below the estimated 86 billion neurons in the human brain. AI data centers are going to need more RAM , folks.
This scientific breakthrough is going to “accelerate our understanding of the brain, and is a major milestone in neuroscience,” noted Google last Thursday. By Tuesday, it was already being trained to play classic video games .

We’ve seen software engineer Alex Wormuth and ‘C++ ragebaiteur’ Jessica Paquette already demonstrate fly-brain video game training. Their fly-brain tinkering focuses on Doom and Mario 64 , respectively.
