Neuro means nerve. Genesis means birth. Neurogenesis is the birth of new experience-dependent brain cells or neurons.

Experience-dependent brain cells allow us to absorb new information, make new memories and learn. Until the late 90’s it was believed that most people stopped generating experience-dependent brain cells by their late twenties. But in the late 90’s it was proven that we continue to generate experience-dependent brain cells throughout life. However, there are some caveat’s attached to this.

First, a brain chemical referred to as Brain Derived Neuronal Growth Factor (“BDNGF”) is essential to the generation of experience-dependent brain cells. The generation of BDNGF is dependent on physical activity. To continue to generate experience-dependent brain cells the individual must be physically active.

Second, experience-dependent brain cells are only available for use for a short time. Therefore you have to use them or lose them. Using them requires the receipt of new information, learning, either formally or informally.

Third, the internal structure of the human brain is continuously changing in response to what the individual does or doesn’t do. That suggests that the internal structure and capability of the brain is either increasing or decreasing in response to the individuals use of new, experience=dependent brain cells.

To continue generating, new experience-dependent brain cells you must stay physically active and continue to learn.
