Researchers Find More Ways That Human and Ape Brains Differ

Underlying the significant differences in brain — to say nothing of the vast difference in mind — is a genetic mystery…

Yale University researchers have identified more specific ways the human brain differs from the brains of all other primates. Using “hundreds of thousands of cells collected from the dlPFC of adult humans, chimpanzees, macaque, and marmoset monkeys,” they found After grouping cells with similar expression profiles they revealed 109 shared primate cell types but also five that were not common to all species. These included a type of microglia, or brain-specific immune cell, that was present only in humans and a second type shared by only humans and chimpanzees. The human-specific microglia type exists throughout development and adulthood, the researchers found, suggesting the cells play a role in maintenance of the brain upkeep rather than combatting disease… An analysis of Read More ›
