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.

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.

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, ...

In a World First, Researchers Mapped Part of a Mouse’s Brain in Incredible Detail. It’s a Leap Forward for Neuroscience The 3D brain map includes more than 200,000 cells, 523 million synapses ...

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 ...

More than 150 researchers worked together through MICrONS to create a detailed 3D map of a cubic millimeter taken from a mouse’s brain — and figure out how the 200,000 brain cells in a speck ...
