I just think that being able to immerse my students in the space itself would be a good way to help them both recognize the relative locations of specific brain regions/nuclei and for them to practice anatomical terminology.  I will try to describe what I am envisioning: I was thinking that I could use a large physical space to 'drop' the student in the middle of a large rat brain (say, 5 meters long). From there, the student could interact by turning on and off some of the structures, for example, the striatum or the colliculi and recognizing their relative distances. They could intuitively recognize that the amygdala is ventral and relatively lateral by seeing it with respect to say, the thalamus. They would be able to see how the third ventricle traverses the hypothalamus. That kind of thing.  I believe that the earlier version for which you sent me a link (v.2) may be more amenable to my idea because the cortex is not too divided up. I don't think I want students to get too hung up on the breakdown of the neocortex at this time.  So I was hoping to take the neocortex as a single element, the caudo-putamen as another (perhaps accumbens separately), the thalamus, the amygdala. These would be the major divisions. Does that make sense?

It very much does, Luis! Pity that Gergely "forgot" to tell you that already in March (your post is.. from May?) we had a runnable Rat Brain VR demo https://github.com/darwinjob/xrviewer

HTC Vive (other headsets too) can do what you describe - it is called room-scale VR. The demo was developed during a weekend by a sole developer. Let me know if you're still interested.
