Why we map the brain
Every neuron you just flew through was reconstructed from a real connectomics dataset. To build one, researchers slice a brain into thousands of ultrathin sections, image them with electron microscopes, and then trace each cell back together, by hand and with AI, into a 3D wiring diagram called a connectome.
Mapping neurons is how we learn how brains actually work. Once we can see how cells wire together, we can begin to understand how those circuits produce behavior, from how a fly decides to walk backward to how a memory takes shape in the hippocampus.
There is far more brain left to map than any lab can finish alone, and that is where you come in. Join the community mapping neuron by neuron and help us continue the journey of discovery.
