It may look like a child’s stacking toy, but a colorful assembly of concentric layers is actually a three-dimensional model of a brain. A series of porous doughnuts, made from proteins taken from silkworm cocoons, serve as scaffolds for rat nerve cells to populate.

The neurons grew in the scaffold for weeks and, in some ways, began behaving as if they were in a real brain, scientists report August 11 in the Proceedings of the National Academy of Sciences. After a har...
