New neurons generated in brains, spinal cords of living adult mammals

New nerve cells in the brains and spinal cords of living mammals have been created by researchers without the need for stem cell transplants to replenish lost cells. Although the research indicates it may someday be possible to regenerate neurons from the body's own cells to repair traumatic brain injury or spinal cord damage or to treat conditions such as Alzheimer's disease, the researchers stressed that it is too soon to know whether the neurons created in these initial studies resulted in an...
