Until recently, scientists believed that once the human brain is fully matured in one’s mid-twenties, no new brain cells (neurons) are produced (that is, no further “neurogenesis”) and the wiring of the brain is set for life (no “neuroplasticity”).
For many decades, it was thought that the brain was a “nonrenewable organ,” that brain cells are bestowed in a finite amount and they slowly die as we age, whether we attempt to keep them around or not.
Groundbreaking research over the past few decades has established the contrary conclusion: You continuously grow new neurons in certain parts of your brain and you constantly re-wire the connections and networks in your brain throughout your life.
