WASHINGTON (AP) — 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 ...

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.

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.
