Professor Howard Eichenbaum outlines some of the major brain structures involved in declarative memory.
The system of brain structures that play a key role in what we call declarative, or everyday memory, involve numerous cortical areas, particularly what we call the high level cortical association areas to process complex information. They funnel their information into another part of the cortex that immediately surrounds the hippocampus, and then there’s the hippocampus itself. So the information flows initially through those structures in that order, from the cortex to cortex surrounding the hippocampus and then to the hippocampus. And interestingly, the information there proceeds back out again from the hippocampus to the cortex surrounding it, and finally back to those cortical association areas. Somehow that two way interchange gives rise to our experience of memory.
