neurogenesis....Can the human brain grow more neurons?

Well, Yes it can. Exactly how stem cells in the adult brain become neurons is a mystery. But scientists have now identified a molecule that appears to help trigger the change. [Reported in the San Diego Tribune, November 2, 2005]...It goes on to say that Fred Gage, of the Salk Institute for Biological Studies in LaJolla found that a protein called Wnt3 is critical to the proliferation of neurons in the Brain. The Salk study was published Oct. 27 in the journal Nature.[In all mammals, neurons are generated in two small parts of the brain: the olfactory bulb, which processes odors, and the hippocampus, which is involved in memories and learning].

Be well,
