You have to a certain extent validated my argument by illustrating close
relationships between the hippocampus, seizures and the storage and recall
of information. You have gone to great lengths to point out that seizure
disorders can accentuate memory problems - which I agree with - and you seem
to have adopted the conventional view that the reverse isn't even worthy of
consideration - which I disagree with. I would argue that the normal,
"excitory" activity that is associated with retrieving memories can become
chaotic if those memories are not retrieved properly. It's my impression
that certain thought patterns can over time, make a person more susceptible
to seizure disorders than others. For example, if a child develops a habit
of obsessively thinking and reflecting on past events (and thoughts), in
time it could theoretically make the brain's juggling act of retrieving long
term memories, short term memories and memories of "reflective" activity -
in a meaningful way - more difficult than it needs to be. Which could in
turn lead to seizure activity, which could in turn worsen the ability to
retrieve memories, which could in turn lead to seizure activity, and so on.
If this is possible then it's also possible that other types of memory
irregularities could also produce similar problems.
It is my own personal belief that a living being cannot experience
consciousness if memories are not arriving constantly in a meaningful way.
I don't mean meaningful as in forming a logical storyline. Dreams put paid
to that idea. What I'm referring to is the ability to create some kind of
meaning at each instant in time.
I suspect that - unfortunately - the latest scientific understanding doesn't
even comes close to establishing the true nature of the relationship between
consciousness and memory. Most people would probably say that consciousness
doesn't require memory. I disagree.
