Fetal brain development in chimpanzees versus humans

chimpanzee, 34–35 weeks) [4], human neonates do have larger brains than chimpanzee neonates [2]. It has been suggested that the extraordinary brain enlargement in humans is due to unique features in the human pattern of brain development during both the prenatal and postnatal periods [1,2]. It has been argued that all primates conform to a 12% ratio of brain mass to body mass from the fetal per...

Chimpanzees versus humans: it's not that simple.

Povinelli and Vonk [1] argue that human beings have a theory of mind and chimpanzees do not. But this black and white picture is exceedingly misleading. We can add the necessary color – on the basis of reliable scientific findings using a variety of experimental methods – by recognizing that the generic label ‘theory of mind’ actually covers a wide range of processes of social cognition. As we ...

Changes in Lipidome Composition during Brain Development in Humans, Chimpanzees, and Macaque Monkeys

Lipids are essential components of the brain. Here, we conducted a comprehensive mass spectrometry-based analysis of lipidome composition in the prefrontal cortex of 40 humans, 40 chimpanzees, and 40 rhesus monkeys over postnatal development and adulthood. Of the 11,772 quantified lipid peaks, 7,589 change significantly along the lifespan. More than 60% of these changes occur prior to adulthood...

Differential Prefrontal White Matter Development in Chimpanzees and Humans

A comparison of developmental patterns of white matter (WM) within the prefrontal region between humans and nonhuman primates is key to understanding human brain evolution. WM mediates complex cognitive processes and has reciprocal connections with posterior processing regions [1, 2]. Although the developmental pattern of prefrontal WM in macaques differs markedly from that in humans [3], this ...

Diethylphthalate, Possible Interactions in Fetal Brain Development

Many natural and synthetic compounds, including a variety of the chemicals used as plasticizers or in the production of cosmetics and therapeutics, have steroid agonist or antagonist activities, altering hormone-regulated gene expression. The phthalate (diethylphthalate, extensively used as a plasticizer and in consumer products, are evaluated using the human renal epithelial cell line 293T/17....
