Debating the Persistence of Neurogenesis in Humans

The question of whether neurogenesis persists in humans and for how long -- that is, whether and where humans grow new neurons in their brains, and how long into our lives -- is one that has engaged neuroscientists for decades. Some papers showed that humans did retain neurogenesis into adulthood, but the issue has been debated. That debate was reignited just recently with the publication of two new studies. The first one, published in Nature, is titled "Human hippocampal neurogenesis drops sharply in children to undetectable levels in adults." Not long after, a second paper was published in Cell Stem Cell, titled, "Human hipoocampal neurogenesis persists throughout aging." To discuss the seemingly contradictory results of these two papers on Neuropsychopharmacology's BrainPod are Dr. Lisa Monteggia, professor of neuroscience at UT Southwestern Medical Center, and Dr. Christoph Anacker, assistant professor in clinical neurobiology at Columbia University.
