Using a songbird as a model, scientists have described a brain pathway that replaces cells that have been lost naturally and not because of injury. If scientists can further tap into the process, it might lead to ways to encourage replacement of cells in human brains that have lost neurons naturally because of aging or Alzheimer's disease.
