Neurons' reverse migration: Exploring the brain's evolutionary architecture

Researchers from the University of New Hampshire looked at the developmental process of the cerebral cortex—the outermost layer of the brain—and examined how neurons, or nerve cells, refine their positions in the brain after birth. Their study shed light on the evolutionary transition from the three-layered cortex, considered an ancient structure, to the six-layered cortex, which is characteristic of higher mammals, including humans.
