Nature's kill switch seems to activate for some brain cells but not others, according to researchers
Preventing and reversing memory loss is a key field of research in the area of prolonging human life spans. While humans are living much longer than they once did, many suffer from debilitating conditions such as Alzheimer's disease and other dementias, which limit their quality of life during their later years.
Scientists at the University of Florida may have gained a significant insight into understanding what causes some brain cells to die, triggering these diseases, while others cells remain alive. The studies, performed on mice examined two neighboring regions in the hippocampus; an anatomical region shaped something like a curved kidney bean. The region is thought to be central to the formation of memories, and is one of the first regions affected by brain blood flow problems or Alzheimer's.
What researchers discovered was that the....read the whole article
