Syntropy (pt. 2)- The Physics of the Brain

In the last blog we discussed the fundamental assumption in classical thermodynamics- that structures move in a temporal progression from states of organization to disorganization.  This is known as the state of entropy.  While our high school experiments certainly showed that nothing contradicts the second law of thermodynamics within the realm of stable, closed systems, things are different in open, complex systems.  In complex systems, the direction is typically from disorganized to better organized.  We referred to this process as Syntropy.

Let's dig a little deeper.

Enter, Systems Theory and Systems Neuroscience,  since I, and many brilliant minds in this field (including some MIT and Harvard brains), see this as the future for research and therapeutic application of the Brain and Nervous System.

First, we must postulate.

"The nervous system is a pattern forming, self-organizing, non equilibrium system governed by nonlinear dynamical laws."


This concept of nonlinear governance of systems is not new to those familiar with Chaos Theory and its sub-branch Complexity theory.  There have been proponents of the idea that self organizing systems move towards increasing complexity and integration for years.  However, it is fair to say that most of what we know about the brain and its physiological operation has been discovered using linear methods.  The relationship between the parts and the whole has been a much debated topic (especially among reductionists and vitalists), and the field of Neuroscience is no exception.  Most studies in the past were carried out within either a top-down or bottom-up framework.

The new story of brain physics, with its new "postulatory"set of lenses, takes us on a new pioneering and groundbreaking journey.  This is because the complex behaviour of a dynamic system cannot easily be predicted or deduced from the behaviour of individual lower level entities, which is something chiropractors have been suggesting for years.  Yet now we no longer need to resort to religious entities or intangibilities to try and explain this Syntropic concept.

In open, complex systems (such as the brain) the constituents are interdependent on many levels.  The brain's emergence and evolution is based upon the cooperation and competition among it's parts.  There is bidirectional interaction between parts and the whole.  And then when this open, complex brain interacts with its environment, special things begin to happen.

The environment (which encompasses the outside world and other people) and the perturbations it provides allow the nervous system to show off its remarkable capacity for learning and growth despite being confined to relatively narrow homeostatic boundaries and simple rules.  In fact, it is this confinement where we witness certain brain "parts" gain dominance over others-  we call this inhibition.  Hermann Haken refers to this as "synergetics" or "order parameter"- essentially the simultaneous action of emergence and downward causation.  In this model, emergence through self-organization, as we have said, is bidirectional.

So now imagine the "bottom up" directional development of a child's nervous system interacting with its environment  where we have local to global causation creating novel and emerging dynamics.  As development progresses, we simultaneously create "above down" global to local determination which, essentially, "enslaves" the constituent parts and effectively governs local interactions.  There is no "agent" causing this "order", IT IS self-organized.  It is circular causation or what is known as "non symmetrical reciprocal causality".

It is this learning and growth or adaptive property of the brain where something greater than the sum of its parts can emerge and this "emergence" is thus qualitatively different from the level it springs from.  The evolving nervous system can now adapt its internal structure so that its dynamics can PREDICT more and more effectively  the consequences of the external perturbative forces acting upon it.  This has spawned some interesting papers with regards to intentionality and free will and caused some in the community to call for a reworking or novel approach to its meanings.

As a chiropractor, I am on pins and needles because  we are not only engaged in the understanding of this ground breaking  theoretical and experimental model of the brain but we have the tools and most rational application to bring it to the world and make an even bigger difference than we already have.

In my next post, I'd like to elaborate more on The Physics of the Brain and how it relates to what we do as chiropractors.  Stay tuned.

  1. Is this similar to the feed forward mechanism discussed by Activator Methods? Thanks, J. Awesome.

  2. Doug, I am not an activator doc so I am not sure how AM explains feed forward mechanism but my guess is yes they are referring to the top-down predictive aspect of the brain. I got a hold of a great pre-press paper (to be published in Behavioural and Brain Sciences) by Dr. Andy Clark out of University of Edinburgh that elaborates on this very topic. He beautifully explained that essentially the brain supports perception and action by constantly attempting to match incoming sensory inputs with top-down algorithms and expectations. He proposes a hierarchical generative model which aims to minimize prediction error within a bidirectional cascade of cortical processing. This essentially unifies perception and action. As Rodolfo Llinas would say,
    "Thinking is the internalization of Movement."

  3. "It is this learning and growth or adaptive property of the brain where something greater than the sum of its parts can emerge and this "emergence" is thus qualitatively different from the level it springs from." Jay, tell me if I'm tracking you in a more global context...Your beautiful sentence above is exemplary and analogous of/to the holographic paradigm which points to how evolutionary, creative, nested emergence has brought forward wonders of our Universe from whence it emerged: The Unified Field. You're helping to answer my questions about just how powerful the adjustment experience can be as it relates to fostering neuroplasticity in a healing process, IE, we chiropractors, with our training and intention, become part and parcel of the resourced, Unified Field for the brain to adapt and grow. Thank you!

  4. Herby, we will want to tease out a key nuance between fostering neuroplasticity and this concept of emergence. I see neuroplasticity as the brain's inherent capability to be mouldable or changed and then "ingrained"....so you can develop both "dysfunctional" and "functional" plasticity. But "dysfunctional" plasticity will never allow the system to be more integrated, which means "emergence" to higher and more sophisticated processing cannot occur. We must remind ourselves of not only our potential to, of course, optimally facilitate this process with our adjustments but also our potential to do harm or null. The power of our neuromodulatory tools is just that.....powerful. "Emergence" can only be a product of careful consideration of how this open, complex system not only produces its own self-organization but how it receives the stimulatory and perturbative nature of your inputs.

  5. Tease well taken, Dr. Whittaker. I concur categorically and have memory of wanting to make this distinction when responding to your post in pure enthusiasm. The broadest context of emergence makes room for such things as supernovae and black holes which may seem highly DYSfunctional in the more specific context you elucidate. A good argument for the here and now, Herby...

  6. Jay, I agree, categorically. Whenever I read/see the word emergence I drop it in the largest of contexts and begin my stream of consciousness adding "nested" emergence that is all inclusive, from black holes to butterflies. Something has happened to me after recovering awareness of this largest of contexts where the holographic paradigm is King and everything is a metaphor of this biggest picture. Thanks for bringing me back to here and now...
