The Developmental Jigsaw: PART III- NEURAL DEVELOPMENT
By Gilbert Valdez & Gabriel Sena
PIECING IT ALL TOGETHER
Enter the phrase that encompasses the complex and dynamic processes we have been speaking about… the developmental jigsaw.
But first, what is a jigsaw?
Simply put, it’s a puzzle.
To an extent, there is a certain high level of abstract thinking (i.e. cognitive development) that providers and parents need to obtain in order to grasp the complexity of this jigsaw IDEA. This concept is asking us to hold in our minds eye multiple degrees of many dimensions of development to form one picture…
…multiple degrees of many dimensions of development to form one picture…
This would be a challenge for anyone.
The developmental jigsaw, the various areas of growth, has one point of origin…
THE BRAIN!
The most complex piece of machinery that has come to exist in the universe (<- said the narcissistic brain), and each of us has one of these 5-pound super computers floating around in our skull. NEATO!
NEURAL DEVELOPMENT
When speaking about development, it is easy to get lost in the trees (the details). What is important to remember is that the deeper/simpler answers are found in knowing about the forest (more so, how an organic forest grows).
When speaking about development, we must step back, and put on our neurobiologist caps. The current wave of advancements in neuroscience is giving us a wider and deeper picture of the impact of neural structure and it’s respective functions.
We are trillions of miles away from Descart’s original ideas of mind vs. body dualism. The consciousness of our modern scientific times, aka the lens we see the world through today, is currently predominated by a lens of neurobiology.
Heck, even the NIMH has pushed us forth into a neurobiological way of thinking (this is the type of scientific research they are funding more often, among others). We can no longer have an accurate discussion about emotions, thought, cravings, pleasure, behaviors, pain, hunger, etc. without the awareness and integration of brain structures and how they function.
What does delayed development imply about neural development?
This is what it all comes down to…
The common denominator…
NEURAL DEVELOPMENT is the foundation in every domain of development.
The genesis. The alpha.The culprit. The protagonist.
Nature via Nurture. Our environment shapes how our genetic code is expressed. Some people are exposed to the harshest of life conditions, chronic stress, poverty, malnutrition, chaotic home environments, abuse & neglect, and other traumatic experiences… Â
Their neural development is skewed, if not impaired significantly, by these exposures.
They literally have all the neural material in their head, but it may be mal-organized or it may be underdeveloped (un-mylinated axons, poor connectivity to other areas of the brain).
Neurobiologists and neurologists have come to discover a neurological impairment/deficit/ hypo/hyper reaction in the brain, correlated to certain behaviors and characteristics. Is this just a scapegoat? Advancement in modern science?
Our brains are wonderful in their plasticity (or so science tells us). The brain is a reflexive organ; it is shaped by what it is exposed to. The chronicity, severity and intensity of these exposures build long lasting highways of neural networks that shape how we interact and perceive the world.
For the providers in the human services field, the people charged with “helping” our species to overcome such adversities, how do we feel when a client with “delays” comes to us asking for assistance?
For those working with children, there is a lot of hope for them still. With repetitive, reparative, rhythmic treatment interventions, the brain has been shown to reorganize, reconstitute its structures and repair it’s functioning. (For more information on this type of work, please see Dr. Bruce Perry’s Neurosequential Model of Therapeutics or The Child Trauma Academy).
Unfortunately, we can’t crack open anyone’s skull while they are still alive, and get a snapshot of their developing brain. We do not have the technology for such a safe and painless procedure. We are limited by the technology of our time.
Stephen Covey, the prolific writer and renowned speaker on leadership spoke of the law of the harvest. In order for a crop to grow successfully, you have to till the soil in the right season, plant the seeds appropriately, water the seeds constantly, pull the weeds out, ensure pests did not eat the growing crop, and harvest when the crop was matured.
This is a lengthy process. It does not happen overnight.
If any of these steps are left out, i.e. just planting the seeds and hoping for a bountiful harvest, the outcome is not going to be a realistic one, and would be disappointing to anyone hoping for a BIG return.
There are no short cuts.
Although, at times, we hope, pray and wish there are.
The developmental jigsaw reminds us to see DEVELOPMENT as an organic process.
Not static. Not boring. But continuous and DYANMIC! (Can you feel the HOPE people!?)
Sometimes, the families we work with, they are hoping for a bountiful harvest WITH their children (e.g. straight As, no Juvenile Justice Involvement, no criminal activity, no dyslexia, high IQs, high EQs, listens every time and all the time, doesn’t talk back… ad infinitum…)[enter your ideals of a perfect child here].
Some caregivers have nurtured and enriched the soil; planted the seeds of education, morality, prosocial values, and communication and watered them constantly; they have pulled the weeds of negative influences, substance abuse; they ensured safety by removing predators and pests to protect their precious crops. These families have followed the law of the harvest, and they are rewarded with the results of such foresight, care and time invested.
Some families we are fortunate to serve, they expect the same results, a “bountiful harvest,” although they may not have followed the law of the harvest.
This is where we do most of our work, and as long as there are fallible human beings, there is work to be done!
We can teach families about development. We can show caregivers how to parent in developmentally appropriate ways.
We can collaborate with school personnel on “where” this child is developmentally so they can benefit from a formal academic education.
We can give the influential people in this youth’s ecology (see Bronfrenbrenner’s ecological model) the necessary and sufficient tools to scaffold successful interventions, accommodations and services so they can catch up.
Isn’t that our hope, for these children to catch up and be successful? To THRIVE?!
Neural development is the forest, understanding the various areas of development are the trees. We don’t have to be a neurobiologist or a lumberjack to understand when a forest/brain is not nurtured, or is not thriving… just look around with a developmental sensitivity.
How complex, each individual truly is… cannot be fully understood, this is a great mystery of the human condition. (But we hope we don’t stop attempting to further our understanding).
Each of us is born into a context; we are molded by an environment; this has shaped and influenced us. Born into a family system full of vulnerabilities and protective factors.
A brain nurtured and stimulated to reflect it’s surrounding circumstances.
We share this, our HUMANITY. We all have a childhood. We were once teenagers etc. Each of us has a unique brain (well, some of us… JUST JOKING!).
Hope you enjoyed these series. There is more to come. Stayed tuned!
