We hear all the time about how exercise is good for the heart. But what about the effects that exercise has on the brain? Well, it turns out that exercise is one more thing that can be added to the list of “what’s good for the heart is good for the brain”! We have used exercise (crawling, creeping, walking, hiking, running, etc.) in our work with children for decades specifically because we were convinced of the organizing effect that physical activity has on the brain. We were also well aware of the many physiological (respiratory, cardiovascular, etc.) benefits of exercise. But Dr. John J. Ratey, Associate Clinical Professor of Psychiatry at Harvard Medical School, has taken the science of exercise to a whole new level.
Summary of Book:
A groundbreaking and fascinating investigation into the transformative effects of exercise on the brain, from the bestselling author and renowned psychiatrist John J. Ratey, MD.
Did you know you can beat stress, lift your mood, fight memory loss, sharpen your intellect, and function better than ever simply by elevating your heart rate and breaking a sweat? The evidence is incontrovertible: Aerobic exercise physically remodels our brains for peak performance.
In SPARK, John J. Ratey, M.D., embarks upon a fascinating and entertaining journey through the mind-body connection, presenting startling research to prove that exercise is truly our best defense against everything from depression to ADD to addiction to aggression to menopause to Alzheimer’s. Filled with amazing case studies (such as the revolutionary fitness program in Naperville, Illinois, which has put this school district of 19,000 kids first in the world of science test scores), SPARK is the first book to explore comprehensively the connection between exercise and the brain. It will change forever the way you think about your morning run—or, for that matter, simply the way you think. (Summary courtesy of goodreads.com)

Why We Like It:
Quite simply, we like it because it provides a solid scientific underpinning to so much of what we teach about the importance of physical activity or exercise for the development, organization, and function of the human brain. Dr. John J. Ratey looks at some of the latest neuroscience as it relates to physical exercise and the brain and the evidence is clear – if you want to perform to your potential, physical exercise must be a part of your regular routine.
One of the wonderful things about the book is how Dr. Ratey shows the incredibly broad impact that exercise has on the brain – learning, dealing with stress, overcoming anxiety and depression, helping with attention problems, beating addictions, regulating hormones, the aging process. This should really come as no surprise since the brain controls literally everything that we do. But it bears repeating since we tend to take the brain for granted and give little notice to how our daily habits are affecting its performance.
Without getting into any details, I want to give special mention to the first two chapters of Spark. They deal with the relationship between exercise and learning and the extraordinary experience of a school district in Naperville, Illinois when they decided to go all in on a revolutionary physical fitness program. You’ll have to read the book to get the specifics but believe me it will blow your mind! I love that Dr. Ratey decided to begin the book with these two chapters because they provide spectacular scientific evidence for the connection between physical exercise, the structural and physiological development of the brain, and the subsequent development of functional ability. He clearly explains in easily understandable terms a physiological process that takes place in the brain when we are physically active. This is research that was completely unknown thirty years ago. The implications of this are critically important for all of us, especially for our children. The bottom line, as we have said so many times, is that movement (i.e. exercise, physical activity, etc.) is the glue that holds everything together in the human brain. The takeaway for your child is to start early and make exercise and physical activity a way of life. Your child’s brain will thank you for it!
It’s time for a paradigm shift in how we look at human functional ability. In his landmark book, The Structure of Scientific Revolutions, physicist Thomas Kuhn coined the term “paradigm shift” to describe the change in thinking that precedes dramatic changes in scientific models. The shift in the field of physics from the laws of motion of Sir Isaac Newton to the theory of relativity of Albert Einstein is a good example.
Traditionally, the medical, psychology and education establishments have assigned human beings to categories according to functional ability – what they can and cannot do, as well as according to how well they do what they can do. This remains the dominant paradigm today. It is most commonly seen in the diagnosis of disabilities – children are placed into categories according to their lack of ability and are then placed into categories within those categories according to the severity of their lack of ability. But it’s been a pervasive idea throughout society for a long time.
Here’s a personal story that shows how this played out in schools when I was young. When I enrolled at Archbishop Wood High School for Boys sometime in the last century, I was assigned to a “track” based on my IQ score and previous academic performance in elementary school. There were three tracks – first, second, and third.
The “first” track was for the kids who had high IQ scores and really good grades in elementary school. It was generally understood that the kids in these classes were going on to college after high school graduation and that most of them would go to top-notch colleges and universities.
The “second” track was for the kids who had average IQ scores and average grades in elementary school. That’s where they put me. It was generally understood that the kids in my “track” would also go on to college but the push for us was to aim for the smaller state colleges where the admissions requirements were not as stringent.
The “third” track was for the kids with below average IQ scores and below average grades in elementary school. It was generally accepted that the boys in the “third” track were not college material and therefore would go on to learn a trade like plumbing or auto mechanics.
Nobody ever told us that the divisions between “tracks” were made along these lines, but we all knew it. And it had a significant influence on how we saw ourselves and our potential and also how we saw each other. It was, in a certain sense, a caste system based on the belief that intelligence is predetermined and unchangeable. So we all thought that if you were lucky and born smart, you were dealt a good hand of cards; and if you were unlucky and not born smart, you were dealt a bad hand of cards. Stanford University psychologist Carolyn Dweck calls this the fixed mindset and when I was growing up the fixed mindset ruled!
The idea that any ability, including intelligence, is predetermined and unchangeable has always been a lousy idea and it has limited the potential of untold numbers of people. But during the last decade or so there has been a movement afoot in neuroscience circles that deserves our attention because it represents a significant departure from the traditional way of assigning children to fixed categories. It is called “neurodiversity”.
Advocates of neurodiversity view neurological conditions like autism and dyslexia as being the result of natural variations of the human genome rather than pathologies or disorders. On that basis, they argue, the traits caused by genetic variations should be celebrated and that there is no need for or possibility of a cure. The neurodiversity movement has seen it’s most ardent embrace amongst the autism community.
Let me give some perspective. Forty years ago, there was no such thing as the autism spectrum. There were simply children with autism and they were categorized as mild, moderate, or severe. That’s it. Some years later, those terms were replaced with autism, pervasive developmental disorder (PDD), and Asperger’s syndrome. Today, those terms have been largely replaced with the blanket term autism spectrum disorder and the children are all somewhere “on the spectrum”. While autism spectrum disorder is still a medical diagnosis that categorizes children according to sets of symptoms (and is therefore not acceptable to neurodiversity advocates) it is a term that nonetheless was greatly influenced by the neurodiversity movement.
While I have fundamental disagreements with both of these developments (neurodiversity and the autism spectrum), they do represent an encouraging trend. These concepts represent ways of looking at human ability that seek to find some commonality amongst all people or at least people with those traits rather than focusing on their differences. And they also at least imply the possibility that performance amongst people who are “neurodiverse” or “on the spectrum” is somewhat fluid rather than static. That’s a big difference from the classical approach of diagnosing a child with a disability and placing him in a box from which he cannot escape.
Nonetheless, these changes do not go far enough because they are still mired in a concept of human functional ability that is essentially based on the idea that ability is predetermined by genetics and therefore is largely unchangeable. This ignores all of the extraordinary advances in our understanding of the human brain and neuroplasticity of the past forty years. So, I propose that we take this notion several steps further.
We have worked with children whose abilities span the entire spectrum of human performance for more than forty years. Since the late 1970s, we have taught a concept that we call the Continuum of Human Functional Ability. A continuum is defined as a continuous sequence in which adjacent elements are not perceptibly different from each other, although the extremes are quite distinct. The Continuum of Human Functional Ability ranges from little functional ability on the low end (as in a child in a coma) to superior functional ability on the high end. When we speak of functional ability we mean sensory, cognitive or intellectual, physical, emotional, and social ability. We mean ability in its most comprehensive or holistic sense. In between the low end and high end of the continuum, there are gradations of functional ability.
In order to understand the continuum, one must first understand that all human functional ability is the direct result of the development and organization of the human brain. You are able to do what you do and do it as well as you do because of the degree to which your brain is developed and organized.
Essentially, the idea is that all human beings can be placed on a continuum that is based on the degree to which the brain is developed and organized. You can see this in any classroom. There is always a range of performance (i.e. ability) amongst the children. That range of performance is, to a very large extent, the result of a range in brain development and organization. Same thing on the soccer team. Same thing in the band. Same thing with children who are diagnosed with disabilities – take ten children with Down syndrome and you will find a range of functional ability, take ten children with cerebral palsy and you will find a range of functional ability.
Remember, these differences in ability are based on brain development and organization not on genetic endowment. Because of that, one’s position on the continuum is fluid. It can change! Improve brain function and you can move up the continuum towards the superior end. Suffer a loss of brain function and you might move down the continuum towards the low end.
We have seen this happen more times than I can count in our work with children who have developmental difficulties. Back in the days before the “autism spectrum” we saw children start our Home Program with a diagnosis of autism. Two years later they came back and their diagnosis had been changed to pervasive developmental delay. Two years later their diagnosis had been changed once more, this time to Asperger’s syndrome.
After you’ve seen this scenario play out enough times you have to say to yourself, what is going on here? If each of these conditions is genetically determined how is it possible that we are changing the diagnosis every two years. Was the original diagnosis wrong? Well, if this experience were only confined to children on the “autism spectrum” perhaps that might be the case. But, it’s not. We have seen the same pattern in children with every diagnosis we work with – cerebral palsy, Down syndrome, Sensory Integration Disorder, ADD, ADHD, and on and on. Over and over again, we have watched children start at one point on the continuum and, as their brain’s developed and became organized, they moved up the spectrum towards a higher level of functional ability!
So, here is the bottom line. We are all, each and every one of us, on the Continuum of Human Functional Ability. I am on it. Conceição, my wife and colleague, is on it. Juliana, our daughter is on it. Same for her husband, Jack. Same for our grandchildren, Jack and Adeline.
You are on the continuum too, and so are your children!
If you have been a regular reader of this blog you know that, as a parent, you have a significant influence on your children and their development. What you do as a parent matters a lot! You can play a role in helping your child find a place high on the continuum.
Finally, and this is the key, ALL of the children who are diagnosed with some type of developmental challenge regardless of the name that the doctors, or psychologists, or teachers have given it, are also on the continuum.
We are all on the continuum! Where we find ourselves is determined by the degree to which our brain is developed and organized. And that, at least as far as functional ability is concerned, is really the only difference between us! I have a great deal in common with the child who is diagnosed with cerebral palsy. I also have a great deal in common with the child diagnosed with Down syndrome. Each of those children has much in common with the other. We are all so much alike!
The beauty of the continuum is that it represents the hope contained in the miracle of the human brain – plasticity, growth, potential. And, best of all, it does this while simultaneously erasing the stigma associated with so many of the antiquated ideas of the past. Diversity is a wonderful thing but so is brotherhood and sisterhood. When it comes to the human brain and functional ability we are all brothers and sisters!
