WASHINGTON, D.C. — 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 ...

The data, assembled in a 3D reconstruction colored to delineate different brain circuitry, is open to scientists worldwide for additional research – and for the simply curious to take a peek.
