polyvagal theory debunked

by on April 8, 2023

This title is click bait. The worst PTSD dissociative episodes can put you into this state. The newest circuit, dependent on the ventral vagal complex, is the product of a ventral migration of cardioinhibitory neurons in the brainstem to the ventral nucleus of the vagus from the dorsal nucleus of the vagus. We would do well to remember this, although we are not encouraged to train our eye here. But that's about where its praises end. Liem Health Blog. Yes, immobilisation is the critical point of the experience of life-threat trauma events. We honour the people who have met this challenge well, they are a success story for us as therapists and we also see ourselves as successful when we render our capacity to be just so. Premise 3: Withdrawal of cardiac vagal tone through NA [nucleus of the ventral vagus, nucleus ambiguus] mechanisms is a mammalian adaptation to select novelty in the environment while coping with the need to maintain metabolic output and continuous social communication. The integration of cardioinhibitory neurons into the ventral vagal complex provided a circuit that integrated suck-swallow-vocalize-breathe processes with a newer mammalian, myelinated cardioinhibitory ventral vagal pathway that is expressed as RSA (Respiratory Sinus Arrhythmia) in the heart rate pattern. Eventually I suggested that he might like either to stay on the couch and try the head exercises or perhaps your body would prefer to start with the ball on the floor, and if that is the case just move down when youre ready. This was the perfect solution as he then easily moved down to the floor and began the session. When responding to their environment, Polyvagal Theory proposes that humans use not only the fight-or-flight and freeze-or-faint responses, but another division of the ANS. Premise 1 and Premise 2 relate to the proposed mediation of neurogenic bradycardia and RSA being dependent on different vagal circuits with the ventral vagal nucleus regulating RSA and the dorsal vagal nucleus regulating neurogenic transitory bradycardia. , Coyne, J. We see great gains when we work with close attention to the individual needs of the system while gently encouraging it to know more. Like we do in the real world, we consciously and unconsciously give higher value to the ability to be able to smile; to smooth things over; to articulate our thoughts with clarity; to use soft eye contact to soothe and engage those around us. Polyvagal Theory. Rights and reuse information. If they would just take a step back from their training and their need to fix what is not broken but is waiting for the right conditions to emerge; they would not only get further quicker, they would learn something magical along the way. The publication of the premises functionally framed the scientific questions for subsequent empirical research to evaluate specific clinical conditions and psychophysiological processes in which this paradox was observable. Sometimes you think you recognise that maybe, just maybe they have found this new point of stasis between the ventral and dorsal states and you need to let take a step back and leave the body to know and then stabilise this new information; or whether maybe it is time to press on and mobilise the body with a gentle exercise; or whether to invite the persons opinion on this and how would that best be done; or whether this will be too much for them to manage at this point. One of the leaders in this field is Stephen W. Porges of Indiana University. Consistent with their straw man argument, with this new PVT attribution, Taylor and his group highlight their finding of a myelinated cardioinhibitory pathway originating in the dorsal vagal nucleus in the lungfish as falsifying PVT. Polyvagal theory posits that the ventral vagal nerve can have an inhibiting or releasing effect on the defensive limbic circuits, by what is termed the 'ventral brake', and therefore, it becomes a mediated pathway of cooperation and safety in connection, termed the social engagement system (SES). The third is immobilized. The oldest of these subdivisions is the "dorsal vagal," a part of the parasympathetic nervous system that enables us to shut down, or "freeze" when a situation of danger feels uncontrollable and we are overwhelmed. based upon Porges Polyvagal Theory, which incorporates the principles of co-design and brain plasticity. Since the premises were dependent on my interpretations of the literature, I welcomed alternative interpretations. We now have amazing brain scans that show which networks in the brain ramp up during different activities. By encouraging this kind of deep visceral connection through 18 months, her therapy can mitigate the effects of autism. Applying a behavioural program with times and duration and intensity and therapist driven, would quickly deaden this process. Taylor and colleagues have questioned the assumption that the dorsal vagal nucleus is an evolutionarily older structure than the ventral vagus. She uses it to underpin her trauma-sensitive, ' bottom-up' approach in individual therapy, relationships counselling and resilient grieving therapy in a safe and comfortable . Premise 2: Neurogenic bradycardia associated with orienting is a phylogenetic vestigial relic of the reptilian brain and is mediated by DMNX [dorsal vagal nucleus]. When you step back and see the brain and body thinking together, the old distinction between reason and emotion doesnt seem to make sense. This show is made possible by financial support from listeners like you. Who are we serving and are we serving them well with our all too good intentions? Rather than assuming a cause-and-effect or stimulus-response model that assumes a psychophysiological parallelism (see Porges, 2022), the theory proposes that autonomic state functions as an intervening variable mediating the response. You're in such extreme danger that you're shut down. Maternal obesity alters the structure, Each year 7,400 women are diagnosed with ovarian cancer in the UK. He and his colleagues have repeatedly misrepresented the theory as stating that only mammals have myelinated cardioinhibitory pathways without qualifying their anatomical origin in the ventral vagus. Premise 4 proposes that the role of the nucleus ambiguus in the ventral vagal complex enables RSA to index the status of the system, which was later labeled as the social engagement system (Porges, 1998). In veterinary medicine, animals like cats often drop dead within the veterinarians office because of the fear and uncertainty. What SE gives us is a map of the human stress response. I think in counseling psychology it's pretty fringe stuff too. Rather than identifying points of disagreement, their straw man argument is dependent on faulty attributions of the theory and NOT on PVT. Filed under Consumer Ripoffs, Fads, Health, Skeptoid Podcast They seem to find the approach useful and it is testimony to the work that they will chose to work with me. In this manifestation of misrepresenting the theory, they have repurposed the word myelinated from being associated ONLY in mammals with cardioinhibitory pathways originating in the ventral vagal nucleus to a general feature of cardiorespiratory interaction independent of nucleus of origin (i.e., either ventral or dorsal vagal nucleus). Connect Join the Community Anita Balogh of Swan Counselling believes that understanding the Polyvagal Theory is fundamental in recovering from trauma, attachment injuries and/or addictions. Polyvagal theory is based on the phylogenic or evolutionary development of the autonomic nervous system. In polyvagal theory, Dr. Porges describes the process in which our neural circuits are reading cues of danger in our environment as neuroception. Aces is a scale that accumulates exposure to adverse experiences, such as abuse, neglect and family dysfunction. A more recent review confirms these conclusions (see attached, Porges under review). Much of this conversation is about how we are relating to others. In some cases, actually frozen and unable to move. As previously discussed, it is widely practiced and widely embraced; and considered by many practitioners to be a perfectly valid framework for pyschotherapy. It emphasizes our evolutionary perspective where we needed different physiological states to . 1 Jul. The polyvagal theory focuses on the autonomic nervous system, the part of the nervous system over which we have no conscious control. As such, what we often label as "bad" behaviors are actually fight-or-flight behaviors, adaptations of the ANS, developed to protect human beings from perceived harm. If bodily reactions can drive people apart they can also heal. It seems, therefore, high time to critically assess the value of Stephen Porges'. When initially formulated (Porges, 1995), PVT was conservatively organized upon several premises or inferences extracted from the literature. There is no evidence supporting most of Porges' proposals for the evolutionary and physiological underpinnings. Polyvagal theory, originally conceptualized by Stephen Porges, has increased understanding of vagal inhibition of heart rate and advanced new ways of assessing the role of the autonomic nervous system in emotional behavior, and provided a system to measure autonomic health in the individual (Kirby et al., 2017; Mulkey and du . Porges's Polyvagal Theory shows that the drive to avoid threat and secure safety is what guides human behavior. Deb is the author of The Polyvagal Theory in Therapy: Engaging the Rhythm of Regulation, Polyvagal Exercises for Safety and Connection: 50 Client-Centered Practices, co-editor with Stephen Porges of Clinical Applications of the Polyvagal Theory: The Emergence of Polyvagal-Informed Therapies, and creator of the Polyvagal Flip Chart. Premise 5 further proposes that the ventral vagal complex is a nexus for the expression of features of emotion (e.g., vocal intonation, facial expressions), which in turn are also mirrored in RSA (see Porges, 1998; Porges et al., 1994). The Polyvagal Theory, now over twenty years old, is used by a variety of therapeutic professions to model how we go offline when we are in a stressed state. Your heart rate may go up. Taylor and his colleagues repeatedly press their inaccurate argument, since they have incorrectly assumed that heart rate-respiratory coupling being solely mammalian is a foundational principle of PVT. Ovarian Cancer Awareness Month 2023 March. A polyvagal theory. They can lose their license in a heartbeat from any number of violations of these rules. We are trying to remind and incorporate them into the system so, as one client described I can have more gears on my bike, but we do not do so at the cost of the dorsal. The Oxford Handbook of Social Neuroscience. Misrepresentation of the role of myelinated vagal fibers in PVT. According to Porges, each branch of the vagus nerve (ventral and dorsal) is . These systems, in the context of mammalian physiology, are foundational processes through which behavioral experiences can lead to sociality and optimal health, growth, and restoration. . All content is Skeptoid Media, Inc. All Rights Reserved. Translated into more real-world terms, it is a . There is more to life than being in a happy ventral state and the deep, dorsal states offer us wisdom, ancient knowledge and an adaptability that streams from the darkness of the dorsal states that we cannot begin to summon out of trained conscious thought. Web. If you want to see a scientific debunking of polyvagal premises, please check out: https://www.researchgate.net/post/After-20-years-of-polyvagal-hypotheses-is-there-any-direct-evidence-for-the-first-3-premises-that-form-the-foundation-of-the-polyvagal-conjectures#view=62d50738ce9881faad0edf95, LATEST: Their nervous systems switch to the dorsal vagal response of numbing or. Misrepresentation of the role of myelinated vagal fibers in PVT. By proposing plausible relationships and identifying the specific metrics to map ventral vagal (i.e., RSA) and dorsal vagal (i.e., bradycardia) function, the research in these disciplines could incorporate a deeper neurophysiological understanding of the mechanisms underlying these observations. While the overall function of the vagus nerve is not in dispute, a growing number of scientists are pointing to evidence that refutes Polyvagal Theory . Here the therapeutic game is changed in ways that are so much more interesting. Society praises fight, accepts flight, but tends to attach shame to immobilisation. Are we of any use to our autistic clients coming from this unquestioned psychological sanctuary? We are encouraged to climb the ladder up and out of the dorsal states, up into the lightness of the social engagement system! When we are in a flight/fight, or more immobilised state, our physical ability to use our social system eyes, ears, voice, connection to heart becomes reduced as our body has turned its attention to safety. So one final word of caution to anyone who is seeing a polyvagal therapist or coach, or any such person. You emphasise the importance of safe spaces for the traumatised. In 1994, American neuroscientist Dr Stephen Porges proposed the Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behavior and emphasizes the importance of physiological state in the expression of behavioral problems and psychiatric disorders. The literature reviewed in previous papers outline the theory (e.g., Porges, 1995, 2007) provided conclusive evidence that in mammals, the two branches of the vagus are profound regulators of autonomic function relevant to adaptive biobehavioral reactions. According to polyvagal theory, shifts in the autonomic nervous system produces three elementary states: rest-and-digest (social and safe), fight-or-flight (mobilisation) or shutdown (immobilisation). Skeptoid Media, You've probably heard of the theory in relation to trauma and behavior, but inherently, the Theory is a biological one. Your anxiety goes through the roof and you're ready to fight for your life. When you enter a new situation, Porges argues, your body reacts. Following their logic, observations of heart rate-respiratory coupling in other vertebrate species would be inconsistent with the theory. However, Dr. Steven Porges's work shows us that there's much more to it and there are actually three . When you trigger feelings of safety, the autonomic nervous system can help health restoration. Can you explain polyvagal theory in laypersons terms? Polyvagal theory empowers parents to navigate your child's intense emotional states. The polyvagal theory explains how trauma impacts both branches of the automatic nervous system. The Polyvagal Theory is the science that underlies mammalian connection and defense responses. Skeptoid Podcast. 1 Mar 2023. The point being made here in an important one about the limits of how one my apply polyvagal theory to their work, but the title suggests a complete dismantling of the theory which is not the authors point. Often it costs them, in will, just to move from one room to the next or to ask their body to pick up a spoon to eat. If we or our client cannot do this, it is assumed that we need to get them back into the mode where they can have this ability, this control, this self-mastery. 1. Your brain then predicts your next action and speeds your heart rate and breathing to deal with it. Much of our society defines trauma by the event when the real critical issue is the individuals reaction. The average person cannot meaningfully distinguish any difference between a "certified polyvagal coach" and a licensed "polyvagal therapist". Poor neighborhoods are full of trauma victims. The criticism of polyvagal theory is equally widespread, and focuses not on its utility, but on its underlying science. A worrying trend in the upcoming world of therapy based on the Polyvagal Theory is the emphasis on the superiority of the ventral vagal states. Premise 1: Neurogenic bradycardia and RSA are mediated by different branches of the vagus and need not respond in concert. Because we have to understand that people respond differently to the same physical challenges. Untreated trauma can be found at the root of much harmful and destructive behavior. She works with families and practitioners, teaching techniques that help to restore the connection between the brain and nervous system. PVT connects biology to emotion, thought, relationships and more. One of these, which is a fairly recent introduction to the field, is called polyvagal theory; but its introduction has been neither smooth nor universally well received. Even with these strong statements qualifying the neuroanatomical structures involved in mammalian RSA, Taylor and his colleagues have misrepresented PVT by stating incorrectly that PVT assumes that only mammals have a myelinated vagal pathway (Monteiro et al., 2018). Polyvagal Theory explains the mechanism though which cues of safety down regulate threat reactions. Retrospective context. Under the old brain-only paradigm, Welch argues, we told people to self-regulate their emotions through conscious self-talk. Holly Bridges, an Australian therapist, author and keynote speaker has developed the Autism Reframe Therapy program (A.R.T.) The Aces scale was derived from Dr Vincent Felittis observations as a physician in the United States. Martha G. Welch of Columbia University points to the importance of loving physical touch, especially in the first 1,000 minutes of life, to lay down markers of emotional stability. Consequently its practice, and its use in therapy, has been fragmented with part of the market providing it as a framework for conventional psychotherapy, and part of the market offering it for sale by untrained, unlicensed providers who call themselves coaches. As a subscriber, you have 10 gift articles to give each month. That's the part of the nervous system that regulates physical and emotional acceleration. Or maybe the threat feels like a matter of life and death. All of this is accepted physiological science and is not in any dispute. The theory had traction because it gave survivors feelings of validation. The Polyvagal theory helps to illuminate the mind-body connections that influence our regulation and activation of the ANS, which can help promote healthy physiological, calm psychological, and positive social behavioral states. Polyvagal theory explains three different parts of our nervous system and their responses to stressful situations. Web. It's best described as a conjecture. You may see a bully on the playground. There is a fine art to holding the dynamic tension between moving forward or staying still in a session. Grossman, P., Taylor, E. "Toward understanding respiratory sinus arrhythmia: relations to cardiac vagal tone, evolution and biobehavioral functions." This mechanism is the basis of social connectedness and cooperation and the system that is . Even if people can use their social system often the ability to know and master the physical is another realm. Were physical viscera, deeply interacting with each other. Unfortunately, others, who have assumed that his statements were scientifically sound, have quoted him and set off a cascade of misinformation in social media. The dispute arose in 1994 when Stephen Porges gave a talk at the annual meeting of the Society for Psychophysiological Research, in which he proposed polyvagal theory. And thats what polyvagal theory described. Within the legal system, theres been a lot of issues when a person hasnt fought off a predator. But is that in fact the most common response to traumatic experiences? And so the various improvements to the science of mental health have been vital steps forward. Stephen Porges is professor of psychiatry at the University of North Carolina and Distinguished University Scientist at Indiana University, where he has created the Traumatic Stress Research Consortium. PVT is an integrative model emphasizing brainstem regulation of the ANS. Given its strong scientific foundation, there has been little criticism of the theory in the scientific literature. Thats a misunderstanding. Premise 5: Emotion, defined by shifts in the regulation of facial expressions and vocalizations, will produce changes in RSA and branchiomotor tone mediated by NA. The three primary neural systems involved in autonomic regulation form a phylogenetically ordered response hierarchy, which is mirrored in development and responds in a predictable order when under survival challenge. Of course, theories must be modified and informed by empirical research and, when necessary, replaced by alternative theories that are more effective in explaining naturally occurring phenomena. These structures are involved in nursing and develop into a social engagement system to detect and signal safety and threat to conspecifics. This circuit, which initially links ingestion through nursing with behavioral calming, provides the basic structures that enable co-regulation and connectedness through the lifespan. So when you become polyvagal-informed you have a better understanding of your evolutionary heritage as a mammal. Rather than assuming a cause-and-effect or stimulus-response model that assumes a psychophysiological parallelism (see Porges, 2022), the theory proposes that autonomic state functions as an intervening . Before we jump into how you can assess the vagal nerve, let's talk a little bit about the autonomic nervous system. 1 Apr. This has been a golden age for brain research. As someone who aligns with being on the spectrum, I resonate deeply with the dorsal state. Lower vagal tones are associated with anxiety. Scroll down to read the entire commentary, or click on any of the sections below to go directly to that section. The most important word there is shame. Dr Stephen Porges first published the theory in 1994. Instead, Grossman has elaborated on Taylors misrepresentation to position himself in social media as the debunker of PVT. Without detouring into a physiology lesson, suffice it to say that it handles the sympathetic and parasympathetic nervous system functions mainly responsible for putting you into and out of the three states. But real emotional help comes through co-regulation. From my perspective the premises were not controversial, but logically derived from the literature. The Polyvagal Theory, in essence, is the science of how mammals connect, but also how they respond to danger.
