How the mouse's brain is scanned, very intrusively.[2] That's both impressive and scary. They're scanning the surface of part of the brain at a good scan rate at high detail. They're
seeing the activation of individual neurons. This is much finer detail than non-intrusive functional MRI scans.
Does the data justify the conclusions? The maze being used is a simple T-shaped maze. The "state machine" supposedly learned is extremely simple. They conclude quite a bit about the learning mechanism from that. But now that they have this experimental setup working, there should be more results coming along.
