If you change the location of mouse, where will it go: place learning (explicit skill); hippocampus, route learning (implicit skill); basal ganglia, can test either early on or after extended training. If you haven"t trained them much, use place learning. If you inactivate bg, still do place learning. If you have trained them a lot, they show route learning. If you inactivate hippocampus, still show route learning. If you inactivate bg, show early learning place learning: fast learning seems to rely on hippocampus and slow learning on basal ganglia.
