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

Thanks to a mouse watching clips from “The Matrix,” scientists have created the largest functional map of a brain to date.

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 study profiles the spatial transcriptomic landscape of mouse brain coronal sections across three age groups and both sexes. Here, authors show a strong female-biased pro-inflammatory gene ...
