The researchers analyzed the brain sizes and diets of over 140 primate species spanning apes, monkeys, lemurs and lorises and found that those who munched on … The researchers also released images that showed how the monkey brains increased in size over the first 100 days after receiving the human gene injection. Thisweight represents anaverage for cynomolgus monkeys of 2.5–5.0 years of age (the typical age selected for general toxicity studies). A study notes that the human brain is three times bigger than the brain of a chimp: “The human brain is about three times as big as the brain of our closest living relative, the … Min height. ===== In an experiment that could portend a real-life Planet of the Apes situation, scientists spliced human genes into the fetus of a monkey to substantially increase the size of the primate’s brain.

Image size; Measurement. 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). Evaluation of brain and body size is important in studies about intelligence. We present an unbiased standard rhesus macaque monkey magnetic resonance imaging template brain volume that offers a common stereotaxic reference frame to localize anatomical and functional information in an organized and reliable way for comparison across individual rhesus monkeys and studies.
