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.

Thanks to a mouse watching clips from The Matrix, scientists have created the largest functional map of a brain to date — a diagram of the wiring connecting 84,000 neurons as they fire off messages.

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, and ...

This color-coded graphic shows different populations of cells in the mouse brain, each one targeted by one of the genetic tools developed by scientists at the Allen Institute and other ...

Analysing a mouse’s brain activity tells scientists where the animal is located and the exact direction it is looking. With further research, the findings could one day help robots navigate ...

Harshvardhan and colleagues have developed a suite of computational tools that will allow other researchers to use these dissection photographs to reconstruct a 3D picture of the brain.

While the mouse experiences the VR environments, the researchers are able to record the animal's brain activity. The team used the MouseGoggles while examining two key areas of the brain.
