removing mercury from the brain

from tk2's excellent post below, i was looking at the hair testing website about the counting method of determining mercury toxicity and was intrigued by a statement made there. they said that mercury stays in the brain.

assuming this is true, what type of protocols are available in order to chelated mercury from the brain? it has been a while since i have had my fillings out and i have done a LOT of cilantro and some fasting. at first, cilantro would kick my butt with brain fog and leave me in a stupor for days afterward. now i can eat a couple of bundles of it in a day and not feel this effect.

knowing the insidious nature of the effects of mercury, i can easily see that i may still be effected with no noticeable effects simply because the mercury itself diminishes the capacity to detect it. does anyone know how i can tell for sure? or have a protocol that, once completed, can give me some surety that i have done all i can for this condition?

thanks in advance for the stellar work you folks do here.
