Birth Of Fresh Neurons In The Human Hippocampus Stops In Childhood

One of the most energetic discussions in neuroscience over the last 50 Decades surrounds whether the human brain renovates itself by creating new neurons all through the life, and whether it might be likely to revitalize the brain by driving its innate capacity of regeneration.

Now scientists from UC San Francisco have established that neurogenesis drops in the human hippocampus all through childhood and is untraceable in adults. Human hippocampus is a region necessary for memory and learning and one of the main locations where scientists have been looking for evidence that new neurons carry on to be born all through the lifetime.

“We discovered that if neurogenesis arises in humans in the adult hippocampus, it is a very uncommon phenomenon, lifting queries about its donation to normal brain function and brain repair,” claimed PhD at the Heather and Melanie Muss Professor of Neurological Surgery at UCSF, Arturo Alvarez-Buylla, to the media in an interview. Alvarez-Buylla’s lab posted the new research this week in Nature.

Alvarez-Buylla is a member of the UCSF Weill Institute for Neuroscience, the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research at UCSF, as well as the UCSF Helen Diller Family Comprehensive Cancer Center. He is a leading specialist in brain growth who over the last 3 Decades has played an important role in convincing the scientific society that fresh neurons are born all through the life in animals such as rodents and songbirds.

In recent years, on the other hand, others including the Alvarez-Buylla lab had already raised questions on whether neurogenesis endures in the human olfactory bulb into adulthood, as it does in particular animals. They have also shown that while fresh neurons after birth incorporate into the human frontal lobe. This procedure also ends at the time of early infancy.
