After injection of spheres, monkeys were killed, the brains were removed and fixed in formalin, and serial hematoxylin and eosin sections of three coronal sections of the cerebrum were examined by light microscopy. Now, I have a problem with this for a couple of reasons, but the main one is that monkeys are gross, disgusting little disease vectors, and the last thing we need is them realizing they can spread germs to humans faster and on purpose.

During the study, Japanese and German researchers injected a gene called ARHGAP11B — which directs stem cells in the human brain — into the dark matter of marmoset fetuses, according to a release about the research. Brain concentrations of total Hg were significantly lower by approximately 3-fold for the thimerosal-exposed monkeys when compared with the MeHg infants, whereas the average brain-to-blood concentration ratio was slightly higher for the thimerosal-exposed monkeys (3.5 +/- 0.5 vs. 2.5 +/- 0.3).

In contrast, if an increase in brain size is (more or less) linearly related to an increase in socio-cognitive skills, then we would predict that the apes outcompete the monkeys especially in the socio-cognitive tasks, while they should perform on a more or less comparable level in the physical domain. Size and shape are the most obvious. Thisweight represents anaverage for cynomolgus monkeys of 2.5–5.0 years of age (the typical age selected for general toxicity studies).
