This is a screenshot of me playing with the BrainVoyager BrainTutor. BrainVoyager make fMRI analysis and visualisation software, and they’re kind enough to offer this interactive guide to different cortical regions for free.

Pictures can’t describe how much fun it is to play with, adding and removing the different hemispheres, labels, views, rotating the whole head, etc. It’s a shame they don’t have more areas programmed in at the moment (it’s just the lobes the gyri and sulci – but there’s a promising ‘forthcoming’ button for Brodmann areas).
