Deep Dive into Dr. John Medina’s Brain Rules

This is episode #43. Welcome to the Neuroscience Meets Social and Emotional Learning podcast, my name is Andrea Samadi, I’m a former educator whose been fascinated with understanding the science behind high performance strategies in schools, sports and the workplace for the past 20 years. The next three episodes will be solo lessons to dive deeper into Dr. John Medina’s episode #42 that I could probably spend the next year on. For those who have not read his Brain Rules book, or would like a quick review, I’ll outline them briefly with thoughts on why they are so important to implement into YOUR daily life with some applicable strategies. Here are Dr. John Medina’s Brain Rules[i]: If you click on the link in the show notes, you will be taken to his website and can watch a video on each rule. I also highly recommend reading the book, because there are so many examples that will bring these rules to life. RULE 1:  EXERCISE: Exercise boosts brain power.   Did you know that “aerobic exercise, just twice a week, halves your risk of general dementia? It also cuts your risk of Alzheimer’s by 60 percent.” (Summary Rule 1, Brain Rules, Page 28). I also heard this from Dr. Daniel Amen in his “Thrive by 25”[ii] online course where he talks about a recent study that rigorous aerobic exercise over a 12-week period, was just as effective for those suffering from depression as taking an anti-depressant.  This class talked about the fact that aerobic exercise, like brisk walking, swimming, running or cycling seems to solve EVERY brain or health problem. The solutions were always to improve your diet and add aerobic exercise. This should be incentive enough for everyone to be sure they are moving at least 3 times a week for at least 20 minutes, or that’s what Dr. Medina would say will have an impact on your brain and improve cognition, problem solving and emotional regulation. I found it interesting that he mentions that strength training did not improve cognition in the studies, but I still think both strength training and aerobic exercise are important to do on a weekly basis, regardless of whether one is making you smarter or not. The latter will definitely make you stronger and is important to include as we age. RULE 2:  SURVIVAL: The human brain evolved, too. I’m sure by now you have heard that the brain’s main function is to keep us safe, something that’s been built in for our survival. If we think about evolution and the survival of the fittest, what happened with the human brain when it evolved and adapted over time was that the brain got smarter with evolution, not stronger. We can clearly see how the human brain and cognition is vastly different than other animals.  The human brain consists of 3 main parts (the hindbrain that developed first, that keeps us breathing, the midbrain that keeps us alert and where our emotions are stored and the last part of the brain to develop, the forebrain that holds the most power with our thinking/reasoning, emotional regulation, and cognitive functions. Our ability to think and reason is what separates us from the animal kingdom and a feature of our brain that we shouldn’t waste or take lightly. Since we have this unique ability, I think it’s our responsibility to pay attention to this important part of our brain and continue to develop and improve our thinking and reasoning skills. RULE 3:  WIRING: Every brain is wired differently. The experiences that you have in your life, “what you do and learn in life physically changes what your brain looks like—it literally rewires it.” (Summary Rule 3, Brain Rules).  This explains why we are all different since “no two people’s brains store the same information in the same place.” (Summary 3, Brain Rules, Page 70). This rule is important to understand since each person we interact with throughout our life will be different with their life experience. We have to learn to read and understand people better, and this can be done with Theory of Mind
