Researchers have created the largest and most detailed wiring diagram of a mammalian brain to date, by mapping cells in a cubic millimetre of a mouse’s brain tissue. In a landmark achievement, the diagram also details the activity of individual neurons on a large scale―a neuroscience first.

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

AI helped the researchers create an astonishing map of part of a mouse's brain, a step towards better understanding how our own brains work.
