Complete brain wiring diagrams
The fly connectome was mapped with a mix of machine segmentation and crowd proofreading. A mouse brain is about 500 times larger. Whether wiring alone predicts behavior is itself an open question: C. elegans has been mapped for decades and is not yet fully understood.
Closed 1986, C. elegans (302 neurons); 2024, the adult fruit fly brain (about 140,000 neurons), FlyWire.
