Mercury paralyzes the glutamate transport proteins

<< Neurotransmitters are chemicals released across the synapse to facilitate signal transduction from the pre-synaptic neuron to the postsynaptic target cell. >>

“Glutamate is the most abundant neurotransmitter used in the brain, by far. It far exceeds all the other neurotransmitters in the brain put together. It makes up 90% of the neurotransmission in the cortex and 50% of the total brain’s neurotransmission. In addition, it also controls the other neurotransmitters. It controls serotonin, dopamine, and norepinephrine… they’re all regulated by glutamate neurotransmission.

[Glutamate neurotransmitters] also, interestingly, play a major role in the development of the brain. So in neural development from inside the uterus until that first three or four years of life, glutamate is playing a major major role, and that’s what’s important to understand. Now, what we’re talking about is the neural transmission that is going across the synapse, how brain cells communicate with one another.

… To much glutamate produces destruction of the entire synapse and its connections. That’s what excitotoxicity is… there’s too much glutamate. Now, even though glutamate is the most abundant neurotransmitter in the brain, it is the most toxic. It is highly toxic. And the brain has a very elaborate system to control that.

… The glutamate transporters play a major role in how the brain is formed. During brain formation, in utero and after birth… those first two years that are so critical, the level of these glutamate transport proteins starts to rise. The reason they rise is to protect the brain against too much glutamate. Anything that interferes with that puts the brain at risk during its development.

And that’s what happens when you expose a child to a lot of mercury… it paralyzes the glutamate transport proteins.”
