FUNCTION AND EXPERIENCE, IN LEARNING, THROUGH THE FELDENKRAIS METHOD Monica Meilleur Let’s begin with the understanding that behavior is an emergent property of the brain. Here, “behavior” means two things. In one sense, it is human behavior or, how we act in the world. In another sense, it is how brain cells behave to act out the biological mechanisms within the brain itself. In both instances, structure and function are intertwined in a non-linear relationship that emphasizes the dynamic nature of the brain and supports the emerging understanding that the brain is highly plastic and capable of change. If the structure of the brain is capable of change then, too, is human behavior. Why would we want to change human behavior? To ask indicates that changing human behavior is in our makeup: the expression of our genes, the structure of our brains, etc. that goes beyond our individual histories and acknowledges the evolutionary nature of what it means to act based on experience. Moshe Feldenkrais, Israeli physicist, engineer, and judo master, understood the complexity of living systems and the functional nature of the organization of the brain. Dr. Feldenkrais noted that we act on our self-image, so to change the way we act in the world we must change our self-image. Here, “self-image” is meant to evoke the somatotopic arrangement of somatosensory inputs in the human cortex known as the “homunculus.” This image of the body in the brain represents the innervation density of the sensory nerve cells on the skin of different body parts, so that areas that are used early and often, like the mouth and hands, occupy more physical space in the brain. Sensory receptors in the skin generate receptor potentials through stimulus transduction, and the homunculus demonstrates that there is a functional organization of the cortical circuits, as cells in close proximity communicate closely with each other. White matter fiber tracts provide physical evidence that these cortical networks extend from the cortex into subcortical structures, which are also related topographically. Therefore, the nervous system continues to grow and change as we act in the world and as we encounter external stimuli. Learning can be defined as this process of acquiring information from the environment. Feldenkrais posited that “learning is latent in the natural laws which have produced our brain and our nervous system and our body and our muscles” (EO, 117). Current models of these structures reveal computational models that engage both feedforward and feedback mechanisms as a means of self-organizing within an environment. Each experience, then, is an opportunity to gather information and to decide what to do next. Dr. Feldenkrais wanted to know, do we have the capability to create environments that will enable this kind of learning? As Carl Ginsburg, a Feldenkrais scholar, put it: “[Before Feldenkrais] no one had tried to put together the evidence from physiology, psychology, and what was known from neuroscience to support a vision of how we could improve ourselves through learning rather than seeking cures” (BMB, viii). Dr. Feldenkrais designed lessons that guide individuals to become more aware of themselves through a process of learning by doing. In a sense, this means that each individual creates an environment within him or herself for learning. Known today as the Feldenkrais Method of Somatic Education, this philosophy takes into account what is going on inside the organism and in the environment (BMB, viii), and therefore invites a correlation between brain activity and behavior. Feldenkrais designed his lessons after the design of the nervous system. He reasoned that if behavior is an emergent property of the brain, then we could learn to speak back to the brain through our behavior, or through the way we function, or act, in the world. Action is an organizing principle for the nervous system. The neuron doctrine describes the neuron as the basic elemental signaling system within the nervous system. Signals are sent between individual neurons and between populations of neurons. Neurons are a diverse population of cells but are largely organized into functional components that include a cell body, axons, dendrites and terminals. Interestingly, a great distance usually separates these parts, which allows two important features to emerge: polarity and electrical excitability. Though not unique to neurons, “polarity and excitability are developed to a higher degree [in neurons], permitting signals to be received, processed and conducted over long distances” (KSJ, 67). Neuronal signaling depends on rapid changes in electrical potential across the nerve cell membrane. During an action potential, the all-or-none output signal of the neuron, the membrane potential changes quickly. (KSJ, 105) Each action potential processes information in functional neuronal networks so that every act within an environment evokes both top-down and bottom-up processes. This dynamic, multi-dimensional approach to information processing in the brain led Feldenkrais to say that human action has four components: thinking, feeling, sensing and moving.1 Though beyond the scope of this paper, each of these aspects of human It seems to me at this time that “thinking” as a biological mechanism is most likely referring to “perception.” 1 action can be discussed in terms of the biological mechanisms that generate them. However, the nervous system processes information by way of action potentials in functional networks. Function is an organizing principle for human action in a broader sense as well because we act in an environment and constantly receive feedback from our experiences. Feldenkrais posited that individual experience is more important in man than any other animal because the adult human brain has “fewer ready-made responses to external stimuli” (BMB, 54). Feldenkrais’s method of education is, in a sense, a project about creating an environment where individuals can pay attention to their experiences. Lessons in the Feldenkrais Method use movement to orient individuals toward this purpose. Why movement? In The Potent Self, Dr. Feldenkrais wrote: We learn to suck, to drink, to eat, to turn the head, to speak, to sit, and to stand, by facilitating some muscular pattern, and all the evidence of mental processes comes to us through voluntary muscular activity. Thoughts concerning realizable action are not any faster than the muscular action necessary to perform them. Every time we speak abstractly of the mind, ignoring its functional whole with the body and the external world, we reach conclusions that have little to do with reality. My contention is that learning always does involve the whole frame, and all learning that does not directly involve muscular activity is poor. (PS, 130-131) Dr. Feldenkrais used his observations of common functional movements, like the ones cited here, as a point of departure for his lessons. For instance, a lesson (which generally lasts about forty-five minutes) might have a student explore how to turn their head to look one way, or the other. Think about how often we engage this pattern to move about in the world! If somebody calls your name from behind, you turn and look. This is a functional pattern that we use to respond to stimulus and, like many behaviors within the brain itself, is a “winner take all” response. When somebody calls, we turn and look. Of all the thousands of subtle “routes,” so to speak, we choose one without thinking. The movement lessons suggest many ways to turn or, in essence, to respond to this same stimulus. Unlike classical conditioning, which relies on timing and repetition, Feldenkrais lessons introduce options and provide a context for processing this voluntary movement within the nervous system, thus strengthening neuronal pathways. In addition, that the lessons signal certain functional activities such as walking, reaching, grasping, swallowing, etc., means there is a context for the newly strengthened neuronal pathways to be put into action in a person’s life. As a system operating on a policy of “use it or lose it,” function is a key to learning. Though movement is the orienting factor, it is not really the individual movements that are important. Instead, the movements afford individuals the occasion to pay attention to how they engage themselves to carry out the movement instruction. Paying attention evokes the top-down processes in the brain, as the frontal and parietal cortexes mediate attention. Meanwhile, we experience gravity as a force through our vestibular apparatus, which evokes bottom-up processing. Remember that information in the brain is processed by the generation of action potentials. As an all-or-none phenomenon, success is measured in terms of whether or not an action potential is generated. This can have an excitatory or inhibitory action on target cells, and different amounts of excitation and inhibition can work together to enhance the stimulus and how we respond to it. To ensure successful generation and conduction of action potentials, Feldenkrais laid out two important distinctions in how to move: First, do only that which is comfortable to do and use the least amount of effort necessary. Second, rest in between each movement so they are separate and discrete. The former instruction is based on the Weber-Fechner law (BMB, 141) and allows individuals to detect much smaller differences. It is these kinds of differences that allow the nervous system to incorporate the new ideas into later action. The latter instruction provides an opportunity for the nervous system to process the information completely during the rest. Both pieces distinguish lessons in the Feldenkrais Method from repetitive exercise or classical conditioning. Feldenkrais lessons are meant to inform the nervous system and in so doing to clarify the self-image. What does it mean to clarify the self-image? It means we learn to do what we are already doing, but better. Feldenkrais wrote, “The human brain is such as to make learning, or acquisition of new responses, a normal and suitable activity. It is as if it were capable of functioning with any possible combination of nervous interconnections until individual experience forms the one that will be preferred and active” (BMB, 55-56). How well an individual functions in the world depends on how well-equipped their nervous system is to respond to various stimuli in their ever-changing environment. Works Cited Feldenkrais, Moshe.
