Mice run through Quake, Princeton neuroscientists scan their brains for traces of evil (video)

Want to know just how prevalent technology has become in our lives? Now even lab mice get Quake-derived virtual reality playgrounds to navigate instead of their old school wooden mazes. In all honesty, this appears a significant and praiseworthy advancement, as the Princeton team have succeeded in mapping brain activity right down to the cellular level, with real-time tracking of single neurons now possible. The Orwellian-looking setup above is necessary in order to keep the mouse's head immobile, and thus capable of being studied, while the animal moves around and its brain performs motion-related tasks. Go past the break to see a schematic of the scanner and a quite unmissable video of it in action.
