Gee, Vince. Did you think to look up what form of mercury they used?
I’ll give you a clue: mercury chloride. They did not use thimerosal,
which has a covalent mercury atom that is liberated from thimerosal as
ethylmercury. Its reactivity is substantially less than ionic mecury
atoms found in mercury chloride. You apparently don’t understand too
much about chemistry.
Here’s their paper and abstract, in case you want to actually read
what they say.

Retrograde degeneration of neurite membrane structural integrity of
nerve growth cones following in vitro exposure to mercury.
Neuroreport. 2001 Mar 26;12(4):733-7.
Inhalation of mercury vapor (Hg0) inhibits binding of GTP to rat brain
tubulin, thereby inhibiting tubulin polymerization into microtubules.
A similar molecular lesion has also been observed in 80% of brains
from patients with Alzheimer disease (AD) compared to age-matched
controls. However the precise site and mode of action of Hg ions
remain illusive. Therefore, the present study examined whether Hg ions
could affect membrane dynamics of neurite growth cone morphology and
behavior. Since tubulin is a highly conserved cytoskeletal protein in
both vertebrates and invertebrates, we hypothesized that growth cones
from animal species could be highly susceptible to Hg ions. To test
this possibility, the identified, large Pedal A (PeA) neurons from the
central ring ganglia of the snail Lymnoea stagnalis were cultured for
48 h in 2 ml brain conditioned medium (CM). Following neurite
outgrowth, metal chloride solution (2 microl) of Hg, Al, Pb, Cd, or Mn
(10(-7) M) was pressure applied directly onto individual growth cones.
Time-lapse images with inverted microscopy were acquired prior to,
during, and after the metal ion exposure. We demonstrate that Hg ions
markedly disrupted membrane structure and linear growth rates of
imaged neurites in 77% of all nerve growth cones. When growth cones
were stained with antibodies specific for both tubulin and actin, it
was the tubulin/microtubule structure that disintegrated following Hg
exposure. Moreover, some denuded neurites were also observed to form
neurofibrillary aggregates. In contrast, growth cone exposure to other
metal ions did not effect growth cone morphology, nor was their
motility rate compromised. To determine the growth suppressive effects
of Hg ions on neuronal sprouting, cells were cultured either in the
presence or absence of Hg ions. We found that in the presence of Hg
ions, neuronal somata failed to sprout, whereas other metalic ions did
not effect growth patterns of cultured PeA cells. We conclude that
this visual evidence and previous biochemical data strongly implicate
Hg as a potential etiological factor in neurodegeneration.

Will you at least admit that mercury chloride and thimerosal are
chemically different molecules? Will you also admit that different
compounds have different toxicities?

I watched the video, but only saw apetri dish. I did not see a brain.
BTW, Brian Heit is on staff at UCalgary…

sure, but it is just a red herring re vaccines, similar to the
autism-is-genetic & autism-increase-is-due-to-better-diagnosis scams

Autism has a genetic component that interacts with the environment. But
that does not make it a red herring or a scam.
Ditto the fact that at least some of the increase in autism diagnosis is
better diagnosis and better understanding of autism.

minimal amount and more likely the genetic component is more sensitivity to
mercury

Bull.
There is a large genetic component. And it is far more than sensitivity
to mercury.
When you get a clue, please let us know.
Until then, I am not going to waste my time responding to you or big
vince in this thread.
Have a lovely day.

Why sure. Mercury chloride From Wikipedia -’Mercury(I)
chloride is the chemical compound with the formula Hg2Cl2. Also known
as calomel or mercurous chloride’ and ………" Due to its low
solubility, mercurous chloride is less dangerous than its mercuric
chloride counterpart. From the early 1830s through the 1860s, this
compound was used as a laxative in the U.S. This previous use in
medicine as a diuretic and purgative was discontinued because of its
toxicity." .http://en.wikipedia.org/wiki/Calomel
again from Wikipedia …. ’Thiomersal (INN) (C9H9HgNaO2S),
formerly and still commonly known in the United States as thimerosal,
is an organomercury compound (approximately 49% mercury by weight)
used as an antiseptic and antifungal agent." and " Thiomersal is
harmful by inhalation and ingestion, lethal between 50 and 1000
times[citation needed][1] the usual intake (hazard symbol T+).[2] It
is a neoplastigen and a teratogen. Thiomersal is also dangerous for
the environment (hazard symbol N).
For more safety information on how to handle thiomersal, consult its
MSDS (material safety data sheet).
Thiomersal causes susceptible bacteria to autolyze (break down their
own cells with self-produced enzymes) via an unknown mechanism.
[citation needed] In the body, it is metabolized to ethylmercury
(C2H5Hg+) and thiosalicylic acid.[3]"
Mercury cloride has been used as a laxative { did doctors really
understand the risk] Thimerosal is much more toxic. Of course any
substance with mercury is a potential toxin. As you know a great deal
about chemistry and biology why would you intimate otherwise. Thanks

Uh, dude, the LD50 of thimerosal (oral testing in rats) is 75 mg/kg.
Mercury chloride’s LD50 is 1 mg/kg.

Any compound has *potential* toxic effects, even dihydrogen oxide.

Oh, I don’t know. Maybe because of all the evidence?
