Layman's question on the biology of Long-term memory.

[Odhinn]

I have gone through a good bit of material on the internet trying to
find the answer to this question:  Where does long-term memory reside
in the brain?  I know the neocortex has a function in forming them,
but where are they stored?  How does the hippocampus figure in?  If a
layman's question is inappropriate for this group, I apologize ahead
of time.
