Adult-brain nerve cell renewal exists but remains poorly understood regionally

Evidence

Even if the role of stem cells in the adult brain and their localization still remain poorly known, even if it is probable that secondary neurogenesis does not affect all regions of the brain, a renewal of nerve cells in adulthood exists all the same, a renewal that, in opening untapped perspectives on brain repair, modifies the way in which we must view the functioning of the brain. — Catherine Malabou, What Should We Do with Our Brain?, 96

• QUESTION: Worth chasing: what is the current state of evidence on adult neurogenesis localization, and do the reader’s brain-flexibility sources reflect it?
