Information, Entropy, and Freedom of Choice – How the Brain Decides

28 Apr

When we work with the brain and neurofeedback, we enter a unique realm of intervention, compared with conventional modalities. Our culture has been built upon an emphasis on the physical and chemical reality within which we live. Our healers tend to be surgeons who work with bones, tissue, and organs. Mental interventions are dominated by chemical diagnoses and medical treatments to “put things right.” Neurofeedback appeals to the “soft” concept of information, rather than the “hard” concepts of chemistry and physics.  Neurofeedback can produce lasting change at the synaptic level, but the mechanism of change is one of information management, not direct physical effect.  It is appropriate to ask, “what does it take to make a decision?” In the most abstract sense, the following things are needed: The ability to discern, the energy to make a change, and the intention to choose. These three factors, discernment, energy, and intention are sufficient to cause any individual or system to change, and to use that change to lead in a particular direction. If any of these factors are missing, directed change is no longer possible.  Neurofeedback operates by making the unseen seen, and by making the unfelt felt. By providing information to the  trainee, neurofeedback provides the key element of discernment (of brain state, via the EEG).

Because we are not normally aware of our brainwaves, this information is missing in everyday experience. Given that brain state can be discerned, what are the factors that allow positive change to occur? Quite simply, they are the presence of the intention to change, and the energy to make that change.  The amount of energy needed to change a system can be exceeding small. James Clerk Maxwell is responsible for the concept of “Maxwell’s Demon.”  This is an imaginary agent that has the ability to determine the temperature of a particle, and to open or close a door that allows that particle to pass from one chamber to another. It can be shown that such an agent could cause a contained gas to become hot in one chamber and cold in the other. In principle, such an agent could create an unlimited amount of energy, simply by letting tiny particles selectively move. In reality, no such demon exists. However, this concept shows us in principle, the immense power of the simple ability to make a decision. And fortunately for us, our brains are endowed with  the ability to make discernments and decisions that facilitate our progress in life, given that we choose to make decisions. This capacity leads to the possibility of learning, or operant conditioning, which is the guiding principle that leads intelligent beings to understand and adapt to their environment.  In neurofeedback, each point earned, each moment of progress, constitutes a tiny decision.

Each decision produces a change in direction, and with proper care, that direction is well determined and purposeful. The presence of information, permitting change, produces no less than the freedom of choice that separates us from all other beings on earth. We  are capable of making discernments, and of making decisions based upon them. When a system is deprived of the ability to discern, or the information necessary to make a decision, free will is compromised. Freedom requires good information, and the clarity to make decisions. In summary, the power of neurofeedback lies in the simple ability of the brain to discern small events, and to make small decisions. Through the progress made during thousands of tiny decisions, great change can become possible, and significant order can be achieved. And what ar e the elements that make this possible?

Belief in change, a willingness to change, and the intention to use the information provided.  Given these precursors, only a tiny amount of energy and  effort are sufficient to reap all the benefits and progress that are there for the taking.

Cost of health care and public policy

9 Mar

I ran across this graph recently, and it underlies the main concern with health care in the U.S. We have an increasingly expensive, yet less effective, health system than any other country in the world. The factors beneath this are many of the same ones we emphasize as mental health and neurofeedback practitioners. Proper diet, exercise, life habits, and avoidance of toxic substances and medications, would do much to alleviate this situation. Yet we do not see much activism in this area. Instead, health costs spiral, and increasing amounts are fed into the insurance industry and big pharma.

Positive steps by government and policy makers to address these concerns, and to provide funding for mental health and interventions based on prevention and brain plasticity would pay off big time,

Something to think about,

Brain and Mind in a Comprehensive View of Mental Health

9 Feb

The science of mental health is converging on a brain-based model of emotional responses and decision-making into a readily accessible format. There is a need for models which can be used by counselors and other mental health professionals with or without the use of extra physiological monitoring or biofeedback equipment. The creation of such a model, however, can make use of scientific methods and processes, that reveal brain activity related to thoughts, feelings, and behaviors, in a global context.

From our perspective, the brain is a pattern-recognition and decision-making machine, that is tailored to operate in the body of an organism. Even though it is a part of the organism, it has its own goals, and its own means of seeking those goals. Whereas an individual may have goals that include safety, nourishment, comfort, social interactions, and other high-level goals, the brain itself has much simpler scope. The brain’s goals are better understood in terms of the mechanics of recognizing patterns, detecting danger, considering options, determining the safety of various options, and, finally, controlling the motor functions that allow the organism to operate in its environment.

In one sense, the brain can be thought of as a parasite, a “rider” that is using its position in the organism to pursue its own goals. The brain uses its host to implement a program that ensures that it will have adequate food, oxygen, heat, and protection. It has further goals that involve thermodynamic and physical optimization, minimization of energy expended, and the seeking of novelty and pleasure, as examples. Indeed, one of the most important roles of a therapist is to help the client get their brain’s goals in line with their own goals. Many disorders, from depression and anxiety, addiction, and compulsive thoughts and behaviors, stem from the brain’s seeking of locally optimized results, blind to the overall goals of the host. According to Gregory Bateson, “The major problems of the world are the result of the difference between how nature works and the way people think.” What we typically think is not “real” and may have little connection with reality.

This is why neuroscience provides a unique perspective on human behavior and mental health. By understanding the underpinnings of the brain’s roles and priorities, we can better understand why an individual would think, feel, and act in a certain way. The individual may believe that he or she is in control of their life, making their own decision, and setting their own priorities. But the fact that everyone is dependent on a properly functioning brain for this to happen means that what we think is going on may be far from the facts. Future posts will describe the relevance of neurophysiology, particularly quantitative EEG and neurofeedback, to understanding and working with these issues.

Noise in the Brain and Free Will

2 Aug

There is an interesting article authored a couple of years ago by Dr Jesse Bengson’s team at the University of California on how EEG “background noise” appears to be important for decision-making.  I find this particularly interesting because it is consistent with one of my ideas about how neurofeedback works.  I believe that in order for the brain to learn, it must spontaneously explore its operating range, and this only happens when there is chaos or noise.  We all have found that  a “stuck” brain will not learn, and that is one reason we tend to apply “unsticking” interventions such as pEMF, EMDR, ISF, and other methods.  So this article not only shows how “noise” is important for decision-making, but that it may be essential to the very existence of choice, or free will.

I hope you will “choose” to read this, and ponder its implications.

 

EEG Imaging and Biofeedback in the Traumatized Brain

3 Jun

screen.2013.09.19_13.31.53The attached talk was presented at the 27th Annual Psychological Trauma Conference in Boston on June 2, 2016.  These results show brain activation patterns that found in individuals experiencing traumatic and emotionally charged stimulation and experiences.  We find that the responses of the frontal lobes demonstrate specific positive and negative emotional responses, and underlie decision-making processes.  The frontal hemispheres are lateralized, in that the left hemisphere and right hemisphere perform different functions, and that both are necessary for healthy, flexible, adaptable responses.  Depending on past experiences, particularly trauma, this balance of reactivity may be affected.  The left hemisphere takes care of sequential, logical processing, and produces positive, or “approach” responses.  The right hemisphere takes care of parallel, recognition-based responses, and produces negative, or “avoid” responses.  Both of these are important, so that the individual is able to respond appropriately to positive or negative stimuli and situations.  Examples are given of both adaptive, flexible responses, as well as fixed, inflexible responses.  Inflexibility is associated with reactive, fixed, and maladaptive responses.  Imaging an biofeedback of brain activity according to this model can be applied to counseling and other clinical activity, to help to empower and enable clients to have healthy responses, that are consistent with goals and produce beneficial mental states and behaviors.2016 Trauma Collura EEG

Toward ecologically valid studies of innovative therapies

23 Mar

A key concern in the development and deployment of innovative therapeutic technologies is the availability of validation studies that support clinical practice. Specifically, the fields of biofeedback and neuromodulation have undergone significant evolution in the past 20 years, with emerging methods including advanced analysis of signals from the heart and brain, and increasingly elaborate feedback schema. These are often based on clinical experience, professional judgment, intuition, and repeated experimentation and variations in techniques.

Controlled studies have been put forth as a “gold standard” in the evaluation of emerging therapeutic methods. It has been put forth that a randomized, blind, sham controlled, crossover design is “the only way to go.” History, however, has shown a very different picture. The rigid RCT approach suffers from a number of critical problems that have, overall, served more to confound and obfuscate the benefits of these methods. Among the flaws in using RCT’s are a lack of ecological validity, problems with subject expectations and the experimental environment, unfamiliarity with the workings of practical therapeutic work, and at times, sheer incompetence on the part of the practitioners.

Controlled studies typically cost 100’s of thousands, even millions of dollars, and require significant planning and resources. They may lack ecological validity, and are often conducted by non-practitioners, and may be conducted in other than an active clinic. If methods are to innovate, the control group should be the existing practice standard, including medications. Studies that have taken this approach have been successful (Meisel, Duric). Hammer (2012), for example, demonstrated similar results for an emerging method, compared to a “traditional” neurofeedback treatment, for insomnia.

Another problem with RCT’s is the cost of absorbing all the treatment costs for all participants, for ethical and scientific reasons. This is then confounded with the fact that all participants are getting free treatment, which affects the level of investment and expectation, putting it outside normal clinical parameters. Studies that fit into routine clinical work can be much more flexible, in that the “control” group, which would be treatment as normal, could be conducted and paid for as usual, and compared with an experimental treatment. This would improve the ecological validity, in that clients receiving actual treatments have the same expectations and costs as encountered in actual clinical work.
