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

To make the map, scientists at Baylor College of Medicine in Houston began by using specialized microscopes to record the brain activity in a 1-cubic-millimeter portion of tissue in a lab mouse ...

The 3D blueprints display more than two miles of neural wiring, close to 100,000 nerve cells, and about 500 million synapses — all contained in a piece of mouse brain no bigger than a grain of sand.

This image shows a digital representation of neurons in a section of a mouse's brain, part of a project to create ... Next, ...

The massive dataset from a new study is a step towards unravelling the mystery of how our brains work and could lead to ...

The even more fascinating part of this study was that the mouse had to have its brain activity recorded while it watched YouTube videos, which allowed scientists to see how different networks of cells ...
