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

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

Scientists achieved “a milestone” by charting the activity and structure of 200,000 cells in a mouse brain and their 523 million connections. A neuron extends an axon to make contact with ...

This image provided by the Allen Institute on April 8, 2025, shows a digital representation of neurons in a section of a mouse's brain, part of a project to create the largest map to date of brain ...
