He and his colleagues recently discovered how to make microscopically thin sections from an entire mouse brain. “Some of these barriers are starting to fall,” Dr. Collman said.

From a cubic millimeter of brain tissue, scientists have constructed a precise, 3D map of the activity in a mouse’s brain, detailing 84,000 neurons and more than 500 million synapses.

Scientists at the Allen Institute, a research center in Seattle, then sliced that piece of the mouse’s brain into more than 25,000 layers, each a tiny fraction of the width of a human hair, ...

One cubic millimeter of mouse brain is about 20 times bigger than the complete fruit fly brain, and much more complex, but the new map is far from a complete rendering. It represents only about one ...

Researchers have mapped the more than 500,000 connections in the intricate brain of a fruit fly larva. This map, they say, could help scientists figure out how learning changes the human brain, too.
