Researchers mapped 84,000 neurons in a mouse brain after it watched video clips. The 3D map links structure and activity.

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 say the map of a speck of a mouse's brain could be as transformative as the Human Genome Project. Here's what to ...

The 3D blueprints show more than two miles of neural wiring, close to 100,000 nerve cells, and about 500 million synapses — ...
