Stroke and Neurogenesis

Does the adult human brain grow and integrate significant numbers of new neurons? Yes, no and maybe, depending on which scientists you ask - but it certainly has the capability to do so. From Newswise: "It appears the human brain attempts to heal itself by giving birth to new neurons following a stroke. This finding, by scientists at the Buck Institute for Age Research, confirms similar studies in animal models and offers new targets for therapeutics to aid stroke recovery. ... The researchers found that cells surrounding the stroke-damaged area carried molecular markers of neurogenesis. In addition, the newborn cells were predominantly located near blood vessels, which have been shown to produce factors that boost cell division and growth. ... The fact that several drugs have stimulated new nerve growth in rodents, suggests that clinical interventions might be developed to enhance this process in humans."
