The sample was cut into thousands of nanometre-thick slices and each was imaged with electron microscopes. AI tools then classified different structures and cells, and created a 3D reconstruction of the sample. “I remember this moment, going into the map and looking at one individual synapse from this woman’s brain, and then zooming out into these other millions of pixels,” says neuroscientist and study co-author Viren Jain. “It felt sort of spiritual.”
