Marr’s theory of the hippocampus as a simple memory: Decades of subsequent research suggest it is not that simple

Marr’s 1971 simple memory theory of archicortex set the stage for over four decades of subsequent research on the medial temporal lobe memory system. Marr’s ideas contributed fundamentally to current computational models of the hippocampus. In particular, this theory led to the widely held view of the hippocampus as a temporary memory store that accurately memorizes events by creating orthogonalized representations (pattern separation), while …
