He might be referring to blue brain, though I recall that simulated 100k neurons from the neocortex (not quite half a mouse brain). The thing is that they simulated the physical processes in the synapses and more for a more accurate representation, so it's actually a lot cooler than it sounds!

Here's a link I googled up: http://bluebrain.epfl.ch/cms/lang/en/pid/56882
