Well, thank you, but I think you over-estimate my knowledge! However I
do have "rules of thumb" and heuristics which I privately apply when
trying to figure out how things work. Having seen many more able minds
than mine make simple topics pointlessly complex, I try not to push my
gut-feelings on other people. I think it's because what makes intuitive
sense to me is not likely to be intuitive to others, and I don't have an
objective framework to fall back on. So I have my ideas, and I enjoy
them, but I stick to the facts in public.

I really don't understand what you're saying here - do you mean
connectional structures in the brain which remain latent unless called
upon by adverse circumstances? Sounds like a target for Occam to me -
there are plenty of mechanisms whereby stress-related changes in
regulatory systems can kick neuronal populations into quite different
patterns of activity. Doesn't need any acronyms or terminology either -
I feel these things are barriers to understanding, and that they tempt
people to think that something is understood.

If you say so - I think the ideas could be re-expressed in a form which
allows others to comment usefully, rather than having to decode your
terminology before addressing the idea.

Thank you - and I enjoy the ideas you express, but would enjoy them more
if I understood them more!
