Thanks, I'll take a look. Neuroscience is enormously interesting.

Depression, anxiety and many other conditions have a firm neurological basis, and mercury affects the brain, so it's more than likely. But I believe there to be other things involved, not just mercury; although if there is mercury in your brain I'd say it'd be the prime culprit.

It's fortunate the mercury can be removed and that the brain can be quite eleastic when exercised and has the capability for growth throughout it's entire life-span.
