Scientists know that the key to unlocking neurological disorders begins with a full understanding of how neurons are generated and sustained.

A new discovery in the secret life of neurons has managed to surprise researchers at the Jan and Dan Duncab Neurological Research Institute at Texas Children’s Hospital and Baylor College of Medicine.

Their findings reveal that the life cycle of adult hippocampal baby neurons was not what was previously thought. 

In fact, very soon after birth, within 1 to 4 days of life, newborn cells reach a critical stage in which many of them die by apoptosis, natural cell death. Furthermore, the study showed that those dead cells are removed quite quickly.

The study blazes a new path for future research regarding the process by which neurons are generated.

“Years ago researchers believed we were born with only a certain number of neurons to last us throughout our lifetime, but we soon learned that new ones are also produced in adulthood. Our current research is focused on the life cycle of those neurons,” said Amanda Sierra Saavedra, postdoctoral associate in pediatrics-neurology at NRI/BCM.
