This is a cool example of science progressing in real time. I had heard previously that the hippocampus was related to navigation (the taxi driver study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC18253/).

On the Wikipedia page for 'Retrosplenial cortex' (https://en.wikipedia.org/wiki/Retrosplenial_cortex#cite_note...), the intro text pulls on a source from 2009 to say, "its location close to visual areas and also to the hippocampal spatial/memory system suggest it may have a role in mediating between perceptual and memory functions."

And here there's new research making that link between perception and memory more clear!
