Where is the difference between human and ape brain development? Brain neurons develop more slowly

The huge brain is a typical human traitThe human brain is the most complex organ of many tissues in the animal kingdom, and even some scientists claim that the brain is the most complex object knownIn fact, quite a few regions of the human brain originally had molecular characteristics very similar to those of our primate relatives, but the human brain has changed dramatically since chimpanzees and other great apes divergedHowever, the genetic and developmental processes behind this differentiation have long been understoodScientistsstudying the human brain believe that brain organs (brain-like tissues) developed from induced pluripotent stem cells may make it possible for laboratory research into brain development and evolutionIn light of this, Barbara Trutreen, a scientist at the Federal Institute of Technology in Zurich, Switzerland, and her colleagues conducted a four-month study of brain organs from human stem cell sources through the development of pluripotent stem cells to try to detect changes in human-specific gene regulationteam then studied the brain organs of chimpanzees and macaques to understand how human organ development differson the same developmental nodes, scientists found that cortical neuronal specificity was more pronounced in gorilla and macaque-like organs than in human-like organsThis suggests that human neurons develop more slowly than the other two primatesresearchers believe their data provide scant resources for a better understanding of the different gene regulatory mechanisms for brain development in humans and chimpanzees.
