Dr. M’s Women and Children First Podcast #69 Repost – Stephen Porges, Ph.D. – Polyvagal Theory


This week I sit down with Dr. Stephen Porges, a Distinguished University Scientist at Indiana University where he is the founding director of the Traumatic Stress Research Consortium. He is Professor of Psychiatry at the University of North Carolina, and Professor Emeritus at both the University of Illinois at Chicago and the University of Maryland.

He served as president of the Society for Psychophysiological Research and the Federation of Associations in Behavioral & Brain Sciences and is a former recipient of a National Institute of Mental Health Research Scientist Development Award. He has published more than 400 peer-reviewed papers across several disciplines including anesthesiology, biomedical engineering, critical care medicine, ergonomics, exercise physiology, gerontology, neurology, neuroscience, obstetrics, pediatrics, psychiatry, psychology, psychometrics, space medicine, and substance abuse. In 1994 he 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 theory is leading to innovative treatments based on insights into the mechanisms mediating symptoms observed in several behavioral, psychiatric, and physical disorders.

He is the author of multiple books on his Polyvagal Theory: including the Neurophysiological foundations of Emotions, Attachment, Communication, and Self-regulation, as well as Polyvagal Safety: Attachment, Communication, Self-Regulation. His newest book cowritten with his son is called Our Polyvagal World, How Safety and Trauma Change Us. Dr. Porges is the creator of a music-based intervention, the Safe and Sound Protocol ™ (SSP), which is used by therapists to improve social engagement, language processing, and state regulation, as well as to reduce hearing sensitivities.

This is such a fascinating conversation. He brings the worlds of psychiatry and anthropological physiology into union for us to understand the why of trauma reactions and the future unwinding that is now possible. This is a must listen to conversation if you know anyone with trauma history.

Please enjoy my conversation with Professor Porges,

Literature Review
1) In a first of its kind study in mice, we see concrete evidence for how the mitochondria in obese individuals are a root cause of disease based on nutritional input. This fascinating animal translational study gives us insight into how a high fat diet is also a major component of mitochondrial damage through fission and fragmentation leading to worsened cell bioenergetics. The cells have reduced fatty acid oxidation or fat burning capacity due to a single gene’s actions. The end result is a tilt toward fat cell production, fat storage and fat cell inflammation which are associated with diabetes and insulin resistance and ultimately metabolic syndrome. This starts to explain the paradox that is obesity where the person has a ton of stored energy, but has limited capacity to utilize it. It is like having a gas tank of fuel with a gas line that only allows for 1/10th of the flow required for optimal function. Science Daily has an excellent review of this paper. Link below. 
2) Women’s brains change during pregnancy as per a new study. The authors looked at brain changes before and after birth as well as with or without a vaginal delivery route. Their study findings noted transient changes in some brain regions as well as permanent changes in other brain regions that turn on self-reflection and empathy for others…… and a recipe of the week.
Enjoy,
Dr. M
