"Neuroplasticity knows no bounds; it is a lifelong journey of growth, learning, and personal transformation." – Dr. Andrew Huberman whose quote we ended our last EPISODE on a “Deeper Diver into Neuroplasticity.”
Making Me Wonder: What About Neurogenesis? 

 
What’s the difference between Neuroplasticity, that we covered on EPISODE #302[i] (that knows no bounds) that’s defined as “the ability of the brain to form new connections and pathways and change how it’s circuits are wired; (as shown so well in the Sentis YouTube video that gives us a representation of these pathways visually, and what they look like in our brain when we create NEW pathways).[ii] This we KNOW we can do throughout our lifetime, (while) neurogenesis is the even more amazing ability for the brain to grow new neurons (Bergland, 2017).[iii]  And on today’s episode #303, we will take a closer look at “What Exactly IS Neurogenesis and Why is it Controversial Among Neuroscientists.”[iv]
Welcome back to The Neuroscience Meets Social and Emotional Learning Podcast, where we connect the science-based evidence behind social and emotional learning (that’s finally being taught in our schools today) and emotional intelligence training (used in our modern workplaces) for improved well-being, achievement, productivity and results—using what I saw as the missing link (since we weren’t taught this when we were growing up in school), the application of practical neuroscience. I’m Andrea Samadi, an author, and an educator with a passion for learning and launched this podcast 5 years ago with the goal of bringing ALL the leading experts together (in one place) to uncover the most current research that would back up how the brain learns best, taking us ALL to new, and often unimaginable heights.   
For today’s episode #303, and in keeping with our Season Theme of Going Back to the Basics, to take our learning to new heights, I’m going back to EPISODE #141[v] on “Neurogenesis: What Helps or Hurts our Brain Cells” because it became clear to me that while researching for our last episode that Neuroplasticity and Neurogenesis are closely connected, but the former is widely accepted, while the latter holds some controversy.
In our first episode on neurogenesis, we looked at:
✔ Tips for regrowing our brain cells (neurogenesis)
✔ A reminder of what prevents neurogenesis and hurts our brain and what we can do to help increase neurogenesis in our brain.
Dr. Andrew Huberman on Neurogenesis
While researching Dr. Huberman’s work last week on neuroplasticity, he mentioned that there was “bad news” with “neurogenesis” and that many people think that they can exercise and add “new neurons” in the brain and “that after age 14, the human nervous system adds few new neurons.”[vi] He said that “in rodents neurogenesis could occur but in humans it was less obvious” and “that while we can’t add new neurons, we can change our nervous system”[vii] and dives deeper into the definition of neuroplasticity and why this holds no bounds. Now I’m starting to see the controversy in this topic, as I went back to my first look at Neurogenesis.
Dr. David Perlmutter (a board-certified neurologist) on Neurogenesis and Dr. John Ratey, the author of Spark: The Revolutionary New Science of Exercise and the Brain
To open up EP 141 from June 2021, I quoted Dr. David Perlmutter, a board-certified neurologist and six-time New York Times bestselling author who said “the best way to increase neurogenesis (regrow your brain cells) is “when your body produces more BDNF (brain-derived neurotrophic factor” (Dr. David Perlmutter) and we covered this topic deeply on EP 274[viii] “What New With BDNF: Building a Faster, Stronger and More Resilient Brain.” I even remember Dr. John Ratey[ix] the author of the book Spark: The Revolutionary New Science of Exercise and the Brain said that BDNF was like “Miracle-Gro for the brain” (you can’t forget some of the things some people say over the years and he cites a paper where he talked
