What is Neurogenesis?

Updated: May 15, 2020

The human body is capable of so many incredible feats of growth and rejuvenation. It can be witnessed through simple wound healing, to liver regeneration, and even regrowth of brain cells. Neurogenesis is the process by which new brain cell neurons are formed in our brains. It occurs fairly rapidly during our embryonic stages and birth stages in the womb when our entire brain is developing and up until the early 1960's it was hypothesized that adult mammals do not regrow new brain cells, but that has been found out to be false. Adults can actually still experience neurogenesis, specifically in 2 brain regions, the subventricular zone and the subgranular zone, containing the hippocampus, responsible for many memory and learning capacities and abilities. The 1980's and 90's saw a boom in brain studies and research. Electrical currents were found to be generated from the newly formed brain cells pointing to the conclusion that they were nerve cells, or neurons. The rate of growth occurring over the course of one's lifetime decreases, but the ability to produce and grow them does not ever go away, especially with the discovery that stem cells in the hippocampus region are responsible for forming the new neurons that eventually differentiate into its specific cellular function. Upon the discoveries of the process of neurogenesis and our own body's ability to continue its brain cell growth into adulthood there are increasingly interesting ways for healthy brain performance and health to be improved. Now that we have an understanding of what neurogenesis is, how can we go about activating this process of inducing the differentiation of brain stem cells into a variety of different neurons to reap the benefits and what exactly are its benefits to us?
