Cell Transplants Fix Biological Clock
Within the nervous system there is a structure called the suprachiasmatic nucleus, a site considered as the biological clock in all mammals, including humans. A new study has found that when this nucleus is damaged or destroyed the rhythm of the biological clock is lost.Research by René Drucker and colleagues was performed in rats because they have well-defined activities at night that have little activity during the day. When some of these rats had neuronal alterations affecting their sleep cycle we could graph the amount of activity during the day and the night. So, when there was an injury that destroyed the suprachiasmatic nucleus, the pace and the biological clock was lost, and the animal equitably distributed its activity during the day and night. read more
