Those of you who, like me, are a little rusty on their neuroanatomy might like to check out a free program called 'BrainVoyager Brain Tutor', available <a href="http://www.brainvoyager.com/BrainTutor.html">here</a>.  The program lets you interactively explore high-quality 3D head and brain models, which can be rotated, moved, zoomed and morphed in real-time.  I've found it very handy!
