Listened to a really good podcast on this subject recently. Highly recommend for those here as it's a much better summary of the Polyvagal theory than what I attempted in this post:

When you manipulate locations in the prefrontal cortex with rTMS the heart rate variability changes. There are trails where depressed are given rTMS while heart rate variability is measured. If there is seen changes they know it is the right location and if not the shift to other locations in the prefrontal cortex. So, there is a "Top-down" from the prefrontal cortex to the body. So, Stephen Porges is wrong. There is also a "bottom up" where the CNS and the body can effect the brain. So, there he is right. Depersonalisation disorder do not come from lower parts of the CNS but the prefrontal cortex the projects to the body. https://www.scienced...935861X19303791

Beautiful, just beautiful!

God, I can't wait to try.

A just published article in "Brain Stimulation" called "A frontal-vagal network theory for Major Depressive Disorder: Implications for optimizing neuromodulation techniques" adresses the interaction between the prefrontal cortex and the central nervous system like the vagus nerve and HRV. 

They show that there is a "top-down" from the prefrontal cortex to the central nervous system in people who suffers from major depression and these changes with rTMS. The claim by the Stephen Porges  that depression and dissociation is a "bottom-up" from the central nervous system to the brain is not true. The prefrontal cortex projects into the body and modulation of the prefrontal cortex in depressed patients with rTMS affects the parasympathetic system and HRV. I think it is the same in depersonalisation. There is likely to be both a "top down" and a "bottom up". 

 

Trauma is not in the body but in the brain that projects it to the body as changes.
