原文开头
How did the human brain acquire a vast repertoire of interneurons? Antonela Bonafina1 and Laurent Nguyen1,2 Responsible for higher cognitive functions, the cerebral cortex of the mammalian brain has undergone pronounced evolutionary remodeling. In the primate brain, this arises from an increase in cell numbers, tangential and radial expansion, and often the emergence of pronounced gyri-fication. These morphogenetic adaptations provided the structural basis necessary to support greater computational capacity and likely contributed to distinctly human behaviors. The evolutionary expansion of excitatory projection neuron populations—those that extend long-range axons to distant regions in the central nervous system—is a well-established hallmark of primate cortical evolution. …
