A Fly’s Brain: A Map of 139,255 Neurons Watch on YouTube

A fly’s brain now has a complete map: 139,255 neurons and more than 50 million synapses reveal surprising complexity.

A fly’s brain now has a complete map: 139,255 neurons and more than 50 million synapses reveal surprising complexity.

We explore the FlyWire project, how electron microscopy and artificial intelligence reconstructed this connectome, what it can teach us about behavior, consciousness, and artificial intelligence, and why mapping a brain does not mean fully understanding it.
