When tweaking its architecture, the adult brain works like a sculptor—starting with more than it needs so it can carve away the excess to achieve the perfect design. That's the conclusion of a new study that tracked developing ...

When you think of a neuron, imagine a tree. A healthy brain cell indeed looks like a tree with a full canopy. There's a trunk, which is the cell's nucleus; there's a root system, embodied in a single axon; and there are the ...
