concentration

Another likely possibility is physiological strength of those connections, which is established by a myriad of factors like the amount of neurotransmitter being released, the type of synaptic receptors and the concentration of those receptors.

Once the researchers successfully got the molecular test working, they conducted controlled experiments using known concentrations of DNA placed in water.

The paper initially concluded that “fluoride is presumed to be a cognitive neurodevelopmental hazard to humans,” based on findings that children exposed to high concentrations of fluoride showed lower IQs than others.

“Our four distribution centers on the West Coast serve a lower concentration of stores,” O’Kelly said in the earnings call.

Instead, there seemed to be a higher concentration in the province of Ogliastra, a central mountainous region.
