Memories are believed to be initially and temporarily stored in the hippocampus and later transferred to the cortex for persistent storage during a process named system consolidation. Alternatively, the cortex may also have a crucial role in the initial steps of memory formation and the hippocampus may not be disengaged from memory processing as early as it has been originally proposed. Here we review earlier and recent studies and hypotheses that address the nature of long-term memory storage.
