Brains memory center needed to recognize image sequences but not single sights

A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus, a deeper structure strongly associated with memory but shrouded in mystery about exactly how. By suggesting that the hippocampus isn’t needed […]
