Yes, there is more to episodic memory than just storing linear
experiences. In fact, each episode seems to be largely unconnected to
the others, for example I can recall a small episode last christmas
when I gave my grandfather an aspirin, but I cannot recall the
preceeding or subsequent episodes.
There is a term sometimes used in psychology, source memory, for our
memory of when and how we learned something. It seems to be impaired
in people with frontal lobe damage, as well as the ability to tell if
episode A came before or after episode B. So my guess is that this
kind of time-binding memory is likely closely linked to the frontal
lobes, although the episodes themselves can be triggered by
electrical stimulation of the temporal lobes.
