There should be a trail similar to the Explore tree on the project specific pages, e.g.
Vertebrate / Mammalian / Rodent / Cerebellum / Granule cell / Solinas et al
to facilitate navigating back to similar projects. Clicking on one of these should jump
to the Explore page with the appropriate place n the tree open.

This trail could potentially be extended when the different (views of) parts of the model are explored, e.g.

... / Ion channels / KM / NeuroML 2
